K&N air filter? Right choice?

[Visionary]

hey guys i have a 07 1krr and have a pcv, full akra exhaust, and K&N air filter on the way. Ive been reading through some threads that the BMC filter is much superior...i was wondering if i should return the air filter and get a bmc? I'm planning on tuning the bike as soon as the parts are installed..any thoughts?

**It seems like the BMC filter reduces engine life from what ive read (i could be wrong..?)

both k&n and BMC make two version filters. high flow & race filters. IMO both are good quality and gets the job done.

I got my k&n filter from http://www.superbikesupply.com/...and it didnt give me an opt for the race filter...

Some people have had fitment issues with the K&N when reinstalling the air box lid, seem the filters are a little to tall.
Running BMC race filters and do not have any issues.

When you say "some" do you mean "all", now im worried...

I have read about this here and on other forums, some people say they just pushed down hard on the lid and tighten the screws extra tight.
While other people say when they do this the lid bows up in the center and the lid does not seal correctly.
I don't have first hand experience with the K&N but you shouldn't have to force the lid to get it on

I have k&n airl filter and i love it.bmc is great filter, but when you ride behind somebody and he makes dust everything will be sucked in the engine.the very small parts from the dust are not filtered.

I have an 07 with K&N filters and there are absolutely no fitment issues if installed correctly. Great filter, I have been using K&N on all my bikes for over 25 years.

OEM provides fantastic protection, and just as much performance. The others are great if you want a filter you can clean, or if you put a priority on have a longer mod list. In day to day riding you will NEVER notice a performance bump with aftermarket.
