What altitude are you typically riding at? How much did your need to bump up the pod mod to?I am running both, I had a little stutter on take off, fixed with the pod mod, otherwise everything is fine, plug looks good. Lots of guys run this set up, a few us needed the pod mod, a lot don't.

K&N is not a paper filter. It is a gauze filter and can be washed and dried out.the only other think i dont like about them is they are paper if they get wet u have to get another one thts y i like foam filter just dry them and roll
I think k&ns work great on na engines but using them on trucks with turbo diesel engines they actually do let too much dirt through the filter and often results in dusted turbos. I was very hesitant to run one on my griz but so far no problem. I think the issue is since the turbo is drawing in 600+ cfm the filter is not adequate for those situations.K&N is not a paper filter. It is a gauze filter and can be washed and dried out.
Over 25 years of running K&N on my toys and daily drivers and not one single problem with filtration and allowing dirt to pass.
I wouldn't say 99%. My opinion is 60%-70% or so.The tip really doesn't effect the performance much at all - it is just a slightly larger
hole so the exhaust note will be deeper. The baffles inside the muffler are giving
99% of the back pressure.
When installing any air filter stock or aftermarket it is crucial to grease the mating surface of the filter that seals to the air box . if you dont do this you are setting yourself for an epic fail . I see too many bikes with clean mating surfaces and dirt in the engine . it even tells you to grease the mating surfaces in the install instructions of every aftermarket filter I have seen . and many even supply the grease in a small tube . did your friend do this ? I have been running K&N filter on my 07 sti for over 3 years now as well as many past vehicles and she is far from factory and never had an issue or problems with maf voltage ( restrictions ) but I am only running 24psi and well over 360hp & 400ftlb to the wheels at 690 cfm with a hybrid ball bearing turbo & 780 cc injectors But you have to clean it and stay on top of it ... to each his own but I have never had an issue .ya idk what he did but alls i no is it blew hi bike and when he pulled it apart it had dirt in the head and i was just making a point about no filter but ya if i had to i would but the only other think i dont like about them is they are paper if they get wet u have to get another one thts y i like foam filter just dry them and roll
