This is a replacement o-ring for your N54/N55/S55 BMW.

Designed with 3M Viton, the only material which can last against heat and the harsh environment of the charge pipe.

This is not the same as the nitrile material used in other kits and by the OE, which is prone to failure.

If your BMW has a N54, N55 or S55, this will replace your existing/worn throttle body o-ring that sits inside the charge pipe.

Fits all BMW’s with an N54, N55 & S55 engines.
