If you are considering filtration other than OEM paper, please first read some test results.



On first glance, the tests look like anything other than paper filters will damage your engine. However, the test is also pouring dust and dirt more or less DIRECTLY into the filters. I don't know anyone who rides in dust storms and that's what you would have to do in order to get the magnitude of dirt that they report.

Also on first glance, it appears that the K&N, Amsoil, and UNI are the worst because they pass more dust. Well duh, they are open filters and that is exactly why I run an open filter. I want MORE air, not less.

One thing I do not see in there is an efficiency curve over time. Paper filters get less efficient and the 'bad' three get more efficient as far as dust goes.

Bottom line, I am going to run a filter that allows gobs of air and that is the K&N for me. Everyone else can run whatever they are comfortable with.

btw, I have been running these filters for years and I have yet to see any damage. I ran an 84 Jeep CJ7 for 12 years and put almost 200,000 on it. A K&N in it from day one and it ran just as good on the day I sold it as the day I bought it. Same thing with a 95 Ford F150 with 140,000 miles.
