    Doesnt need to be fitted to an S3 with a k04 if your thinking about it.

    I would of thought a fpr is an fpr...

    I am sure that as long as they bosch units then all good, but they are all different pressures so be aware of that. 4 bar from Audi A4s and Passats from 1995 to 2001 ish

    Not unless your tune calls for it !

    No benefit just sticking one in randomly

    As Mark says...not unless your map needs it.

    I tested adding one when at the Dyno with my S3 and lost power due to running too rich.

    I'm thinking of getting an mbc +diode mode.. But, I read that if I'm gonna add some psi I should fit a 4 bar fpr. Car is a S3 8L BAM. Does it comes with 3 bar or 4 bar?
