BMW B58 Intake High Flow Kit for G20/G22 Models

The RVNG G-Series High-Flow Air Intake is a complete replacement for the factory airbox on the B58-powered BMW G20 M340i and G22 M440i. The brief was simple: build the largest, loudest, highest-flowing intake on the market.

It starts with a massive 6" velocity-stack air filter feeding a 4" aluminum pipe that mates cleanly to the turbo inlet — no restrictions. The MAF sensor sits in the same orientation as factory for accurate readings. With no extra tuning, peak gains run from 12 to 20HP (fuel and elevation dependent), and every component works together to add power and torque across the band with an aggressive, race-inspired sound.
