ive been searching and you cant search for k+n because its only 3 letters or some bull**** like that....well i was searching, and mostly 5th gens were having my problem so i thought id post here (im a 4th gen)....well yesterday after chaning my fuel filter, i got a hissing sound....but it wasnt from the fuel filter....came from my k+n...anyone know what a cause of this is....it sounds like there is a leak in the K+N itself, making the "SSSSSSSSSSS" sound.....should i be concerned about this?

 

do u just have the filter or did u replace the whole intake system with a midpipe

 

if you have an intake... you may have bent some of the fins on the k/n. the k/n filter on our 4th gen project car has soooo many fins bent, the car has hissed a different tone every time we work on it. Oh well, the air flow and filtering capabilities are not going to be affected so much that you should take notice.

some hissing is normal though i know on my car, friends tl, my 97 the intake hisses a little

 

ive got the filter with the removed resonator and custom upper intake....so its nothing i should be worried about?

 

No. It's normal

 

Ive got it to, only at a certain range of the throttle, almost sounds like a whistle
