MTC Motorsport BMW B46 B48 Charge Pipe Kit. The MTC Motorsport 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 port welded for those running their cars on methanol. Hard anodised in black to improve durability. It will fit the following vehicles with the 2.0L B46 or B48 engine.
