So I dropped in a k&n panel filter today and just wanted to clarify something. I expected more noise from the intake, but should the engine be humming now? Definitely wasn't doing that before I put the filter in. Its a low him, but noticeable. Any input is appreciated

 

I had the same issue recently when replacing the stock filter with a new one - very noticeable (and annoying) low hum. So its not necessarily the k&n. Make the sure the filter is oriented correctly and fully seated in the air box....or simply replace the whole mess with a CAI...

 

CAI still makes noise.. just a different one.

not sure about the hum u speak of. is it all the time. or only when the car is warming up?

at idle only or all the time..?

give us the deets

 

Make sure all your screws are tight, had the same problem before but found out the clamp and screws were not tight enough

 

^Yep. Everything seems to be together and tight but in fact it's not and leaking.

CL-S, the hum is most noticeable at idle when you're outside the vehicle. In my case, it was not subtle. It was bordering on Holy Crap, What's That territory.

 

I only removed the two screws closest to the drivers side fender, lifted it up, switched them out, and re-tightened the screws. It is very noticeable at idle, especially loud when you open the hood. Sounds like a vacuum, I just wanted to see if this was normal. I don't see how I could've possibly screwed it up just by doing the process I did. If it comes down to it, I may remove it and sell it, not a fan of the noise

 

Its not normal. Did you recheck the assembly?

 

everyone's definition of a sound is different.. so the hum u think u have... some may hear ur car and tell u ur nuts.

but u are comparing it to before. so u gotta keep that in mind.

my guess is u are beating a dead horse...

did u crack anything? did u replace the screws properly? did u install it right side up? if yes.. stop doubting urself
