So I finally decided to try this simple "mod" out. We have these medical grade magnets at work and when they expire it just ends up as trash. Rather than throwing it out I decided to use it for this. These are small magnets with VERY strong pull. I proceeded in covering the K&N filter with it. It took 26 of these magnets to cover the top, next time I plan to make a sleeve and fit around the filter. My concern is that will all the potential magnetized particles (hopefully very little to none), isn't it more engine damaging if those were to break loose and starts recirculating as a big chunk versus separate tiny pieces? I will have a dirty deed in a few weeks when my oil change is due and I will have to dissect the filter to see how much magnetized particles where trap. I'll try to post a picture of it then.
