I'm new to the Porsche Brand, but itching to try my next mod.
My first mod consisted of a "simple to install" bolt-on plenum that replaces the original stock plenum by Peak Aire Performance, which has yielded 36 to 37 MPG highway driving ( see pic ) & 20 to 23 MPG city.
Not sure if these MPG ratings are good or bad, however the original sticker price label when the car was sold read - 20 City 29 Highway - Comments Welcomed!
Question:
Has anyone successfully increased the size of the stock TB & Intake Plenum from 68mm to 74mm?
I would like to combine the increased performance from the first mod with a larger plenum & TB from a different Porsche model.
Does anyone have the recipe for this "DIY" cocktail?
