Technical Data

As part of our expanding BMW product range, AIRTEC Motorsport is proud to launch our intercooler upgrade for the E46 320d model suitable for track or fast road use.

In order to ensure there is no noticeable loss in performance during extended periods of hard driving, we have developed a larger, freer-flowing intercooler that is a direct replacement for the smaller and more restrictive OEM item.

Our solution to increasing the intercooler’s size and performance within the confines of the limited space behind the bumper is based upon a taller core with an increased 110mm depth. 

Together with our high-flow, moulded one-piece cast end tanks to ensure flow is directed correctly and efficiently, the AIRTEC Motorsport intercooler offers much greater efficiency and volume over standard.

Available in a high quality powder coated black finish, the comprehensive kit is a direct replacement comes with all fixtures and fittings, as well as detailed fitting instructions.

Please note: your original boost pipe flanges/fittings will need to be cut in order to fit this intercooler.

Height: 140mm
Width: 676mm
