Re: how to quiet a K&N fitler?
thanks sarge. I hand some tiem free today, and looked into some of the new setups. It appears that those 'boxes' are actually layers of acoustic damping / plastic shell..IE, they're masking the noise, not getting around it. I've also listened to the Niva while a friend drove it down the block, and its considerably quieter outside than in ( meaning its a resonance, not just a 'noise'.)
with a 30" long hood, and future plans calling for a turbo, and intercooler, I dont have room for a huge airbox...right now I'm thinking of experimenting with a lined tube (to damp out the resonance), and a roof height snorkle, to move the noise outside the body: any suggestions or thoughts before I start cutting holes in my body shell ?
