I would like to get some advice from people who have used both these types of filters. Is a K&N filter any good for a two stroke engine in DUSTY dirty conditions or is the foam filter type best for this condition? I heard that the K&N's are good for 4 cycles(more tolorant of dusty air) and 2-strokes under dune/desert conditions(low dust).

Anybody ever take apart an engine that was run with a K&N or foam air filter and see any internal dirt?

Anybody ever loose an engine from dirt getting inside due to one of these filters?

Thanks,

I use a prodesign/K&N filter withg a outer wear on my 96 banshee. I run T5's also. I just tore my engine down for the 1st time. It looked super clean in the inside. Reason for taking it a part is getting some mod work done.
So I have had good luck with the K&N

What would you say the conditions you ride in are like, Sandy(dunes), dry dirt(dusty), or moist dirt(muddy)?

k&n for sand and foam for dust. was on the phone with Allen Knowles from ct racing today and he told me that a k&n will pass the smallest particles in dusty conditions. I currently run a k&n on my 400ex and have noticed that if you run a white rag through the boot between the airbox and the carb you will find dust. The reason I was asking him about filters was to get his recommendation for which one to run with his pipe. He recommends a k&n for the sand and races like the baja because a foam fister in a long race like this will plug and then everything passes through

 

I just redid the top end on my 99 bansee it had a uni foam filter on it first and dirt was gitting in to the carbs.Then I put a K&N filter with the pro designpro flow filter adaptor never seen a spec of dirt anywere not even doing the top end.I hope this has helped you. majicmike
