Oil Filtering Cover for KTM’s

These Oil Filtering Covers have been developed with a magnet manufacturer with a doctorate in material engineering. It’s a replacement oil filter cover that contains a strong magnet to filter out additional ferrous particles from the oil as they pass through the filter. The magnets are manufactured and licensed to fit this application. They have a higher pulling strength than normal rare-earth magnets enabling the size to be in keeping with the original OEM covers.

On the newer filters for all the KTM Adventures, SM’s, Dukes, all RC8’s and LC8’s, there is a release valve, so if the filter blocks it opens. For example, if the water pump seal seeps or due to high mileage service intervals the filter collapses, the valve will open. BUT, there will be NO oil pressure warning light – madness!

If this happens, all the oil will flow past the cover at its strongest point, continuing to filter the oil and trapping any hard, ferrous particles. So it’s an added protection, additional peace of mind.


On all the LC8’s there is a pressure release valve in the oil pump housing. When the pressure is too high, a piston moves held by a spring which then dumps oil back into the sump. So the bypass valve in the filter must open before the oil pump release valve. In our opinion this has not been thought through correctly.

The filter cover has been designed to highly magnetize the steel cap and steel centre core of the oil filter. The magnetic field extends deep into the oil filter chamber filtering the oil circuit, not like a sump magnet.

It is critical not to have any possibility of corrosion or any contamination in the engine, so the magnet is fully encased. You’ll never struggle to get your oil filter out again, but keep the cover at least 3 inches away from your phone, credit cards etc!

We have manufactured two types for the most popular KTMs:

Round – p/n. 75038041200 and Chamfered – p/n. 59038041000

This is a pair of big pliers, only on the steel cap of the bypass valve style oil filter, so you can see how much it magnetizes it, and a selection of metric sockets illustrating how strong they are.


They are machined from solid billet 6082 aluminium and anodized, with the correct sized high quality nitrile O-ring, two M5 flanged bolts and fitting instructions. This is a premium, high end item and is not mass produced. Though it doubles the cost of one oil change, it will help keep the engine’s oil cleaner, extending the engine’s life and will not deteriorate over time.  Follow its developement on the UK KTM Forum.

The Round Cover 75038041200. Fits the 690, Adv’s, RC8, SM, Duke most of the 990’s, all the new 1**0 LC8’s Adv’s, Superduke, 09 onwards 450 XC-W, 09 onwards 500 EXC. And many more.


The Chamfered Cover 59038041000. Fits all the 950’s, early 990’s, 450SMR, 450SX, 505SX, 525, 450XC, 525XC, RFS 250. And many more.


Please double check your bike’s part number before ordering. Some models of the same year can have either cover depending on the manufacturing year of the engine cases and not the year of the bike’s registration.
