If you're looking for the ultimate Cold Air Intake for your BMW B58-powered M140i I M240i I 340i I 440i, the MMR Performance intake kit is simply the most sophisticated and highest-flowing option on the market.

The dual-entry high-flow air filter is at the heart of the intake, fixed into an aluminium bell-mouth design. By removing the OE airbox's inherent restrictions, this 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 also beautifully finished with billet support fixings and stunning, real carbon fibre support rods, looking stunning 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.

Coated in our proprietary anodised finish for durability our Cold Air Intake upgrade will boost your engine's performance, enhance intake noise and engine bay aesthetics all in a matter of minutes thanks to the easy installation - which is also fully reversible with no cutting or permanent modification required. Full install kit of quality stainless steel hose clips and all fitting hardware included - to look good and keep looking good.
