Relocation kit for expansion tanks with a B48 setup in E46 chassis. Uses the existing old air box threaded holes in the chassis. Can also be used with other engine swaps but only fits an E46 and gives it a factory look.
Mounts both the engine and intercooler expansion tank
Does not include expansion tanks - for use with part numbers 17138617045 (intercooler) and 17138677649 (engine)
Pre installed hardware makes it super easy to install
