Does a K&N Filter improve sound?
 

I used to have an LS400 and there was a cheap air intake mod to add a dramatic intake noise on WOT.

I now have an ES330 and realize that such a mod is not possible, but was wondering if I did replace the stock filter with a K&N would it make a difference in the sound?

I would assume not as the stock airbox is likely very muffling.

And yes, I completely understand that there are negligible or negative improvements to actual power most intake mods, but I'm willing to sacrifice a few ponies for a better noise on WOT

Thanks for any replies

If you want more intake noise remove the resonator inside the fender.

Agree on the resonator, the K&N filter alone won't do it. To get some real noise you do need the intake.

I may be asking too much, but is there any instruction to do this?

thanks!, i'll keep this in mind if i decide to mess with it

This is a picture of that resonator.
