K&N Induction Kit
I know there have been similar threads before but.....
Has anyone had any experience of fitting a K&N Induction Kit to an S3, is it worth it?.... do they sound better??
Re: K&N Induction Kit
open filter = sucks in hot air = bad
CAI = heatshielded = sucks in outside air = good
They make slightly more noise than the OE airbox, and really, thats the only reason to upgrade.... Very little happens in the performance department.
BMC CDA is the one to go for
