Re: 74mm throttle body upgrade
Yes, but realize that the OEM plastic IAT/MAF piece will be a restriction unless replaced with one off a model with the 74mm.
You will reuse the old sensor if the new plastic piece comes with one.
Also very important to order a couple of new O rings for the TB before starting.
The ideal scenario is : 74mm TB, NeedsWings CAI ( either single or dual ) and a Eurocharge tune.
