FilterMAG Oil Filter Magnet (SS365) $60
The FilterMAG SS365 Oil Filter Magnet fits oil filters with a diameter from 3.50" to 3.90" (which covers all Land Rover V8 applications including the Land Rover Genuine Parts ERR3340 Oil Filter and K&N Performance Oil Oil Filter). The eight Neodymium magnets attract and trap metal particulates as small as 2 microns in size and holds them tightly against the oil filter's walls. The SS365 will immediately begin cleaning your engine's oil without restricting or otherwise affecting oil's flow.
FilterMAG Transmission Magnet (TM360) $58
The FilterMAG TM360 Transmission Magnet snaps onto your transmission pan and will attract and hold the countless steel particulates that are circulating in your transmission fluid, particulates that are too small to be stopped by the transmission's filter. Snap TM360 onto the bottom of your steel transmission pan. The TM360 will immediately begin cleaning your transmission fluid without restricting or otherwise affecting transmission fluid's flow. The TM360 is equally suitable for use on your engine's crankcase sump, where it will attract and collect the countless steel particulates that are circulating in your engine oil. The TM360 will immediately begin cleaning your engine's oil without restricting or otherwise affecting oil flow.
Modern oil filters remove particulates by forcing the oil through paper-based media with very small pores. The pores are small enough to trap most particulate matter in the oil but are large enough to permit the oil to flow at sufficient rates to lubricate the engine. The technology behind this filtering medium is an inherent compromise that has remained relatively unchanged since the 1930s. While it is necessary to filter the oil to remove harmful contaminants, it is equally important that the oil flow back into the engine quickly enough and with sufficient volume to lubricate all of the engine's moving parts. A "perfect" oil filter would trap all particulates down to 1 micron in size (about 1/70th the thickness of a human hair). Unfortunately, a filter with ports that small would also starve the engine of oil and cause engine failure. Filter medium developments over the years have increased the efficiency and life cycle for oil filters, but fluid dynamics still require the ports in the oil filters to remain at about the 25-micron size or larger to maintain sufficient oil flow. In other words, particulates smaller than 25 microns in size flow right through the oil filter.
The countless tiny particulates that would otherwise flow through your oil filter to exacerbate wear on your engine are caught by FilterMAG's powerful Neodymium magnets. The patented FilterMAG Oil Filter Magnet Technology removes steel particulates as small as 2 microns in size from engine oil, yet does not interfere with oil flow in any manner.
To remove minute steel particulates from the oil system, magnets must have enough energy to attract and hold the incredibly fine particulates against the velocity of the oil flow. FilterMAG's patented design employs a focused magnetic force field that amplifies its powerful Neodymium magnets to generate the immense force needed to attract and trap minuscule sub-20 micron particles from the oil flow, as well as retain the smaller particulates as small as two microns in size against the pressure of oil flowing through your engine's lubrication system. FilterMAG's patented magnetic flux amplifier technology redirects the magnetic energy normally present on the far side of the magnet towards the inside of the filter canister. The flux amplifier has to be of a precise thickness to maximize the magnetic field. The circumference is adjusted to allow for manufacturing variances to result in a precise fit & alignment of the series of magnets to the filter canister. This focuses the maximum amount of magnetic energy within the oil flow.
Simply place the FilterMAG on the outside of your oil filter housing, where the FilterMAG's powerful magnetic forces automatically snap it into place. Shown for illustration purposes is the FilterMAG attached to the K&N Oil Filter on John's Defender. Once mounted, the FilterMAG will not slip off. In fact, removing the FilterMAG is quite difficult and the FilterMAG must be slid off. It cannot be pulled off using hand force.
The ultra strong magnetic forces start to work immediately, forcing countless microscopic metal particulates to be "locked" against the inside walls of your oil filter.
Above is a synopsis of several different tests conducted by Predictive Maintenance Services on a Chevy diesel engine that has a Harvard Bypass System. Test numbers 88532, 88069, and 79299 were conducted WITHOUT a FilterMAG placed on the oil filter. Test number 95049 was performed WITH the FilterMAG in attached to the oil filter. While the spectro Fe (iron) stayed largely the same, there is a huge drop in the particulate count (350 on test number 88532 without the FilterMAG and only 58 on test number 95049 with the FilterMAG). The symbols ">2" and ">5" refer to particulate sizes: 2 microns and 5 microns, respectively.
The SS365 FilterMAG is designed for the oil filtration needs of both automotive and truck applications. The SS365 fits oil filters with a diameter from 3.50" to 3.90".
The eight Neodymium magnets act in concert to trap steel particulates as small as 2 microns in size.
Here is a typical oil filter showing the particulates trapped by the FilterMAG after 1,500 miles of use on a 1999 Lincoln Navigator. These particulates are small enough that they would have bypassed the vehicle's oil filter medium and never filtered out of the Navigator's engine oil. Without the FilterMAG, these particulates would still be floating in the vehicle's motor oil.
Here is a Land Rover Genuine Parts ERR3340 Oil Filter pulled from Ho's Discovery. The oil filter was fitted with a FilterMAG and then the vehicle was driven around for 3,000 miles.
Here is a close-up of the same oil filter. The silver-colored bits are larger chunks of metal that the FilterMAG caught before they even reached the filter element. These larger pieces would probably have been caught by the filter element. The countless black pieces are smaller metallic particulates that were floating in Ho's crankcase oil. These smaller particulates are the type that are small enough to pass right through the filter and are never filtered out of the crankcase oil. The FilterMAG captures both large and small particulates. The amount of particulates on Ho's oil filter was not inconsiderable. The build-up of particulates on the inside of the oil filter wall was such that the accumulated debris formed raised mounds.
The metallic particulates ranged in size from visible bits to almost invisible pieces. The smaller pieces were small enough that they felt almost like grease instead of a metallic paste. The FilterMAG attracts and traps particulates that small. These are the same particulates that are so small that they go right through the oil filter.
After cutting open the oil filter to check it, we removed the FilterMAG and placed it on Ho's new oil filter. It's that easy.
Here is the oil filter from a Baja Bug after only 45 minutes of race use. Just as with the oil filter from the Lincoln Navigator and Ho's Discovery, the particulates adhered to this oil filter are small enough that they would have bypassed the vehicle's oil filter medium and never get caught. Without the FilterMAG, these particulates would still be floating in the vehicle's motor oil. With the FilterMAG attached, all of these particulates are trapped and cannot harm the engine.
The K&N Oil Filter has a diameter of roughly 3.7" and accepts the SS365 FilterMAG.
The Land Rover Genuine Parts ERR3340 has a diameter of roughly 3.8" and, like the K&N Oil Filter, accepts the SS365 FilterMAG.
Also available from FilterMAG is the TM360 Transmission Magnet, which snaps onto your transmission pan and will attract and hold the countless steel particulates that are circulating in your transmission fluid (particulates that are too small to be stopped by your transmission's filter).
The TM360 features two very large Neodymium magnets. Snap the TM360 onto the bottom of your steel transmission pan. The TM360 will immediately begin cleaning your transmission fluid without restricting or otherwise affecting transmission fluid's flow. The TM360 is equally suitable for use on your engine's crankcase sump, where it will attract and collect the countless steel particulates that are circulating in your engine oil. The TM360 will immediately begin cleaning your engine's oil without restricting or otherwise affecting oil flow.
The TM360 is very thin in profile and will not affect ground clearance. You won't even know it's there.
Just snap it onto your engine or transmission pan. The very powerful neodymium magnets will hold the TM360 securely in place.
The TM360's benefits are very real. Here is a transmission pan removed from a Range Rover Classic to show the TM360's effectiveness. The Land Rover transmissions are fitted with magnetic drain plugs. Land Rover owners who do their own gearbox maintenance know that the magnetic drain plugs catch only the larger particulates. This is because the factory magnetic drain plugs do not have the drawing power of neodymium magnets.
Here is a close-up view of the same particulates. Note how fine the particulates are. They are so fine that they resemble grease when mixed with the transmission fluid. These fine particulates are not caught by the factory magnetic drain plugs or transmission filter and would be floating around inside the gearbox. But with the TM360 fitted, they are stuck to the side of the gearbox pan.
Don't be misled by the numerous copycat versions out there. There is only one FilterMAG. Nobody else utilizes the patented technology that FilterMAG does.
FilterMAG is also the only magnetic oil filtration device on the market today that uses Neodymium magnets. These high-intensity rare-earth magnets produce five to 10 times the magnetic force that ceramic magnets do. That is what separates FilterMAG from other copycat designs. FilterMAG's patented technology enables it to collect ferrous particulates as small as 2 microns in size, even though these particulates are extremely small in size and are moving quickly through the oil filter with the oil. Other copycat designs cannot do what FilterMAG does.
Neodymium magnets are for real, and are used by top-quality toolmakers in the automotive industry. These telescoping pick-up tools are manufactured by Ullman Devices and sold through professional-quality tool sellers like Snap-on Tools, Matco Tools, and MAC Tools under various private labels.
The large magnetic pick-up tool is about the size of a Sharpie marker, yet easily picks up a Land Rover front halfshaft. Such is the power of Neodymium magnets. Standard ceramic magnets do not have this kind of pulling power, which is why companies like Ullman Devices, Snap-on, and FilterMAG use only Neodymium magnets. The large magnetic pick-up tool is especially suited for fishing out vehicle carnage in the field.
The small magnetic pick-up tool is pen-sized and designed for picking up misplaced screws and other bits, but will easily pick up this Snap-on 3/8" Locking Flex Ratchet. This is very impressive performance for a magnet as small as this.
All of the foregoing premium tool companies use Neodymium magnets because they are several times more powerful than ceramic magnets of the same size and perform their task better than standard ceramic magnets. For the same reason, FilterMAG uses only Neodymium magnets in all of its units. Only Neodymium magnets have the power to attract and trap the smallest of microscopic metal particulates that are floating in your engine oil. These microscopic particulates flow through your oil filter with the oil at a high rate and would otherwise pass right by a conventional ceramic magnet.
We also highly recommend replacing your differential drain plugs with the Land Rover Genuine Parts Magnetic Drain Plugs. The Magnetic Drain Plugs come standard on the Disco2, but also fit the front and rear differentials on Land Rover vehicles with solid axles such as the Defenders, Disco1, and Range Rover Classic. A large magnet on the tip attracts and traps metal particulates inside the axle casing and prevents these particulates from causing additional wear to the differential, gears, and bearings contained within the axle. More importantly, the presence or absence of metallic particulates on the drain plug at service time gives visible indication of possible problems with your drivetrain components.
These drain plugs do not have the power of the neodymium magnets used in the FilterMAG, but they are better than nothing and do trap a considerable amount of particulate matter.
