Anyone change their air filter or done a cold air feed?
My TDI 130pd is going in for a remap in approx 3 weeks
Before it goes in, i was thinking of improving the air flow. Does anyone have any experience of this on a TDI?
I currently have two options:
1 - Replace standard air filter with aftermarket - e.g pipercross / K&N etc - i know a few guys have done this and although theres no bhp increase the throttle response has been improved quite a bit.
2 - Keep standard filter and do a cold air feed into it? - not sure if anyones done this on a TDI yet - is it even possible or worth it?
