To anyone that has this product how does it performe and have you had any problems with it.

 

It performs great, such a product you'd expect from a prestigious company like K&N. It makes a low, resonant tone in your engine bay that impressed my girlfriend. as far as performance, it does the job for $60 with better throttle response and noticeable fuel economy improvement, but if you got the money to spend, I suggest you wait for the K&N SRI thats suppost to be released soon.. rumor has it that it should run about $350 with a few HP gain. and PKG includes heat shield.. if you look up K&N in one of the threads, someone has a pic of it..

 

thanks

 

If your hearing a "resonant tone" then your airbox isnt sealed properly at the bottom. When you removed the stock filter the clips that lock into place on the bottom of the air box probably came "unlocked" causing the resonant tone you are hearing.

I know this for a fact because I am on my 2nd lancer (have 08 and 09) and my 08 was real loud after the oil change place checked my air filter, I never bothered to look into it. I recently got the k&n filter for my 09 and i put it in (in my dark apartment parking lot) and i heard that resonant tone. I was on the way out so i didnt bother to check it.

When I took the stock air filter to my dad (who now owns my 08) to put into his car I installed it with better lighting and noticed that his air filter wasnt sealed properly so i removed the old one which had 32k miles on it and put my stock one from my gts. once i fixed the air box and drove around in it there was no resonant sound anymore.

I then went to my gts and did the same to my k&n and the sound was gone.

Fix your filter before more dirt gets in there, else you will be buying a k&n filter cleaner/oil kit in about a month.

 

hahaha, your girlfriend is not really used to be being impressed is she?

 

she loves me for my car. lol. j/k. I just fixed it. you were 100% correct.. I miss my resonant tone but better to have a clean engine than nice sound. I appreciate the heads up. Time to look for an exhaust to make up for the lost note. any suggestions? im kinda on a student budget but I love to show the brands on my car.. max spending limit is $350 any thoughts or ideas are appreciated

 

good nice to know it helped ! if you miss that sound I would have bought a SR intake but k&n is good and dealers dont get all pissy about them.

try RRM for the exhaust they have a dcent one, or Greddy TI-C .
