what is the best for my 300ex a uni, k&n, or other im looking for the most gains. i was also thinking about taking my lid off?

 

If your looknig for the most power kn N but they dont protect as well if u wont somthing that will last is like a foam liek uni or twins, but ive heard if u you run pre filters or somthing with KnN its just as good as foam

 

I don't really trust K&N. They are so thin, even with an Outerwears I can't see how they are ever going to catch everything that nature is going to throw at them. Leave them for the street, or racers who are going to do frequent rebuilds anyway.

Go with engine protection, over a littel gain in performance! I like the foam UNI or White Bros. filters for the 300. The foam is thick enough that you at least have some backup against failure.

Think twice about pulling the lid off if you ride in the wet! If you take it off, I highly recommend the EHS Racing lid with an Outerwears cover (http://www.ehsracing.com/).

 

I had K&N for a while, but then I found some particles of dirt in my intake boot. I immediately switched ot UNI. I recommend you buy the Uni.

 

Same here I raced go karts and the K@N let dirt in. ANy foam kept it out. THe HP gains with a K@N were minimal and not worth it at all. UNI all the way.


If you ride one trip with a K@n fliter and you ride behind someone on a dusty road you will have tons of dirt in the motor.

You want see any pro dirt riders using K@N.
