Injen 20-22 BMW M240i/M340i/M440i/xDrive Evolution Roto-Molded Air Intake System W/ SuperNano-Web

Injen has been making performance parts for a long time, and they're known for their well-built intake systems. This Evolution Roto-Molded Air Intake System, part number EVO1108, is designed specifically for a range of BMW models like the M240i, M340i, and M440i, all equipped with the Turbo B58 or Turbo Hybrid B58 engine. It's built to let your engine breathe easier, unlocking more of the performance you're looking for.

What sets this intake apart is the massive SuperNano-Web Dry air filter. It uses Injen's Twist-Lock system, which lets them use the largest filter possible for this application. More filter surface area means more air volume, which translates to noticeable power gains. Injen has dyno-tested this system and found it can add up to 13 horsepower and 11 lb-ft of torque. The one-piece roto-molded housing seals well against the factory air scoop, making installation straightforward and helping to ensure only cool air gets drawn into the engine.

Installation is designed to be simple, often taking around 20 minutes, thanks to the Twist-Lock filter mounting and minimal parts. The kit includes quality hardware like stainless steel clamps with protective liners and automotive-grade silicone couplers for a secure fit. You'll also notice a more aggressive intake sound when you accelerate.
