BMW 435i Performance Air Intake – Dinan – Carbon Fiber (2012–2018). A sealed cold‑air system designed to reduce restriction and feed your N55 with cool, dense air.

An optimized carbon fiber tube follows the factory path with a straighter, freer‑flowing design, feeding a larger sealed airbox and an enlarged cylindrical filter. Expect crisper throttle response and a richer intake tone. Dinan cites gains of up to +10 hp and +15 lb‑ft on many N55 applications without additional mods (results may vary). Typical bolt‑on install takes under an hour. Note: some convertibles may require minor brace modification—see instructions.
