My A4 is going in for a Full Service with Audi and they wany £59 for a replacement Air Filter.
Would it be cheaper/better to get a replacement K&N or similiar brand?
Also where is the best place to get one from. I can't find any on the net.
Whats best and what kind of benefits are there?
If any improve the noise it would be a benefit!
Thanks in Advance!
