I installed a K&N airfilter in my 2000 legacy gt limited a few months ago. Is it nornal to be hearing a rattle noise when the accelerator is pushed now? Is there a fix for this? This noise only started once the K&N was installed. Or is there another brand of air filter that people would recommend and not make the rattling noise?

 

Thanks for the help

What's rattling? Is it a panel filter?

The ones from the dealer or the Purilator ones from Auto Zone work fine, and they don't have big holes in them like the K&N, so there is less chances of larger dirt particles getting into your engine.

it sounds like a panel rattling...and continues to you let off the gas at high speeds. it is a panel filter.

do foam filters work very well? I was thinking about trying one

Does only happen when the engine is cold? COuld be piston slap. Which is noraml for a cold Sube engine.

 

You might want to check that the filter box is closed properly.

i have checked the filter box already.

I think it also does it when the engine is hot

FWIW, I put a K&N in my '97 OB maybe 30k miles ago and am happy with it, no rattle for me. I did find it a little tricky getting it in there and closed up nice and tight.
