MMR Performance Air intake Kit – BMW B58 M140i/M240i/340i/440i – MMR11-0502FK
The dual-entry high-flow air filter is at the heart of the MMR intake, fixed into an aluminium bell-mouth design. By removing the OE airbox’s inherent restrictions, our intake will support the increased performance outputs that a highly-tuned B58 engine can produce, whilst unlocking a truly addictive soundtrack at the same time. You’ll hear the rich induction noise from this race-bred intake the first time you accelerate hard!
The heat-shield is a very important part of this intake kit. It retains the factory cold-air entry feed, plus ensures that this cold, fresh air is shielded away from the heat generated from the turbo and exhaust manifold. The heat shield is beautifully finished with billet support fixings and stunning, real carbon fibre support rods; looking great in the engine bay.
Meanwhile, we’ve incorporated rubber-mounted billet fixing mounts to allow for compliance under engine-rock and prevent any undesirable NVH (Noise, Vibration, Harshness) from entering the cabin. In other words, every aspect of this intake has been considered and obsessed over in the minutest detail.
