Dinan Carbon Fibre (Carbon Fiber) Cold Air Intake / Induction Kit for BMW 135i & 335i xDrive N54 Twin Turbo (E82 E88 E90 E92 E93, 2007-2010) - Performance Airbox Lid, Ram-Air Feed, Cone Filter Upgrade

Carbon fibre induction upgrade for N54-powered BMW 1 Series and 3 Series

Give your twin-turbo straight-six the airflow it deserves with this premium Dinan carbon fibre induction system. Designed for the N54 in the 135i and 335i, this high-flow setup delivers cooler charge temps, crisper throttle response and that addictive turbo spool and whoosh. It is a direct-fit replacement for the OE airbox lid and adds a secondary front-end feed for a genuine cold-air path, all while transforming the engine bay with motorsport-grade carbon weave.

Why enthusiasts choose this intake

• Flows significantly more air than the factory airbox for stronger mid-range punch and extended pull to the redline
• Secondary front grille feed supplies fresh outside air to the cone filter for reduced heat soak
• Integrated shielding around the filter helps keep intake temps down - measured up to 40 F cooler at the inlet versus stock
• Hand-crafted carbon fibre construction - lightweight, rigid and stunning under the bonnet
• Refined turbo induction soundtrack without excessive cabin drone
• Direct bolt-on with factory-style fit and finish - no cutting required
• Pairs brilliantly with software, intercooler and exhaust upgrades on the N54 platform

Real-world results from MJ Modifications

We have installed this intake on multiple customer builds and our own N54 projects. Feedback is consistently positive - quicker spool, cooler IATs, stronger mid-range torque and a great turbo soundtrack. The fitment is tidy, the carbon finish is top tier and the gains compound nicely with a remap, uprated intercooler and a freer-flowing exhaust.
