Cen-Cal Motorsport Silicone Front Mount Intake – BMW G-Series B46 / B48
Upgrade your G-Series BMW with the Cen-Cal Motorsport Silicone Front Mount Intake, engineered for the B46 and B48 engines. This direct-fit upgrade replaces the restrictive factory intake with a high-flow, multi-layer silicone design for better airflow, faster spool, and a louder, more aggressive induction sound.
Built from premium reinforced silicone, it resists heat and pressure while maintaining consistent boost response. Installation is simple with OEM-style fitment and all hardware included.

High-flow multi-layer silicone construction

Direct bolt-on fitment; minimal trimming required

Reinforced for pressure stability under boost

About Us
What started as a group of BMW enthusiasts tired of overpriced parts and limited options is now a brand trusted by thousands of owners nationwide.
We designed our own product lines from the ground up and built the production infrastructure to make them happen. No middlemen, no compromises. Just the parts we actually wanted on our own builds.
Now we operate out of Oceanside, California, engineering valved exhaust systems, carbon fiber, forged wheels, front-mount intakes, and more. Everything is designed in-house, tested on real platforms, and stocked locally for fast shipping.
This is just the beginning.
