MTC Motorsport BMW N55 M135i M235i M2 Charge Pipe Kit. These charge pipes fit the latest N55 single turbo petrol engine. The BMW part number is 7515387. This also won’t fit any of the older N55 engined E chassis cars. The MTC Motorsport N55 charge pipe features. Made from lightweight 6061 alloy pipe which is mandrel bent for a smooth flowing bend. Very easy connection to the throttle body as it keeps the same CNC connector. The pipe is 3″ diameter which is matched to the size of the throttle body and down to 2.5″ to meet the intercooler. Beaded ends and mikalor clamps included so that there is no chance of hoses blowing off. Massively increases throttle response and eliminates a lot of lag. Meth ports welded in for those running their cars on methanol. Hard anodised in black to improve durability. They will fit the following vehicles. Does not fit LHD X-Drive models as it touches the steering rack. Included in the kit. This is a direct bolt on to the car. You can use the standard clip on both the throttle body and intercooler. If you have lost the clip on the throttle body because the pipe has cracked and blown off then we also sell the clip. If you have any doubts at all that this won’t fit your vehicle you can send me a picture of the standard charge pipe on the right hand side of the engine and I will confirm which charge pipe you need as there are around 4 different variations.
