I'm thinking of changing to a sports panel filter. Would it be recommended to do the exhaust at the same time or is the filter on it's own for a while going to cause a disadvantage?
Hey guys. I'm new here and I know pretty much nothing about improving car performance.
I own a Citroen C3 1.6 VTR. Are there any worthwhile gains with this car without spending loads or increasing fuel consumption by a silly amount?
Hope to hear from you guys soon :)
