STROM B48 Air Intake Box
The STROM B48 Air Intake Box is a purpose built intake solution designed specifically for B48 engine swaps in the E46 chassis. Constructed from lightweight and durable Nylon PA12, it offers a clean appearance along with excellent heat resistance and long term reliability.
This airbox was originally developed for Strom B46 powered race cars to eliminate the need for hand made custom intakes. The design pulls cold air from the lower right front corner of the E46, where airflow is cooler and cleaner. During testing we moved away from cone style filters after seeing higher intake temperatures and filters becoming dirty after only a few weekends. This box solves both issues by sealing the filter from engine bay heat and using a more efficient airflow path.
An optional built in port allows you to monitor air pressure between the filter and the turbo inlet to check for potential pressure drops from a clogged or restrictive filter. This is especially useful for track cars or high power applications.
The airbox is designed to use BMW air filter part number 13727843284. This filter is inexpensive, seals properly, and provides excellent filtration.
Each kit includes the two piece airbox, the inlet tube that connects to the turbo, a crankcase breather hose, hardware, and hose clamps.
