–  NOTE: Early B5-S4 cars with the Bosch MAF Sensor,  will need to purchase a Hitachi MAF and wiring pigtail to convert the car to Hitachi. purchase SKUS 034-701-0000 and 06C133471A both available on our website.

NOTE for Exhaust Components: For this tune and fueling kit to perform well, we recommend at least 2.5 inch downpipes paired with at least a 2.5 inch, true-dual, cat-back. For optimal performance of the kit, we recommend 3 inch downpipes going to a single 3.5 inch or 4 inch cat-back. We recommend 034Motorsport’s Downpipes and 3.5 inch Cat-Back, both of which can be found on our website.

NOTE for Intercooling Components: For this tune and fueling kit to perform well, we recommend at least having Evolution Racewerks Side Mount Intercoolers (ideally, with carbon fiber shrouds).
