Re: intake for a tdi (speedR)
Well, in my case and after some experimenting on the dyno with my car and a friend´s TDI, we both recahed the same conclusion: no gains at all, even if well vented and heatshielded..
It seems to me that the stock airbox is not restrictive at all, even the new PD150 engine uses the stock A4 airbox/snorkel..
On the goodside, a cone filter has a cool induction sound and the the turbo lag seems to improve a bit..it´s your choice!
