BimmerWorld Silicone Throttle Body Boot - E46 M3 (S54)

Our BimmerWorld Silicone Throttle Body Boot is a considerably better option than the stock plastic intake elbow on the S54 6-cylinder engine in your E46 M3. While the stock piece is obviously functional, it leaves potential power on the table. The sharp corner creates flow turbulence, and the overall shape of the stock part is less than optimal.

Designed using the same features as the intake sections on our professional race cars in World Challenge and IMSA, this high-quality silicone replacement hose adds real power and throttle response. With a reshaped profile, more filtered air volume is available, essentially increasing plenum volume. This boot is the perfect add-on for a performance panel filter or performance intake systems that don't replace the factory plastic boot. The high-quality, 4-layer silicone construction will withstand anything you can throw at it for years to come. 

Important Fitment Notes:
Our throttle body boot is intended to fit everything from the stock intake plenum/air box to many aftermarket applications, and therefore the ends will likely require trimming to fit properly and provide smooth airflow for your specific application. If the boot is too small at the end or too long for the space, it will need to be trimmed back to fit. This is especially true for S54 swaps (in E30 or E36) where more trimming is required. We suggest a new snap-blade knife and straightedge for this task. Remember: Measure and mark twice, and cut once. 

Fits all E46 M3 Coupe/Convertible (2001, 2002, 2003, 2004, 2005, 2006).
