JB4 N55 (F -Series)

JB4 for N55 engines found in the F20, F22, F30, F32 and other F-Chass BMWs.

One of the best tunes on the market, in our experience will add 30-40kw at the wheels to an otherwise standard N55 powered car.

Comes standard with flex fuel connector and for electronic wastegate models, the ewg connector.

Most 2012 - 07/2013 builds feature the pneumatic wastegate, and 07/2013 onwards are electronic wastegate. If you are in doubt contact us and we can clarify.

Installation available at our Sydney workshop, contact us for a quote.
