F10 550i N63 Cold Air Intake & Strut Brace Kit Dinan Part #11742

Dinan Part #11742: cold air intake and strut brace combo for F10 550i (N63 engine, 2011-2013). Not for N63TU or later. Designed for fast road and track day use - not daily driver compromise.

• Engine-specific: fits only F10 550i with pre-facelift N63 (not N63TU, not F10 535i, not F07 550GT)
• Stage 1 compatible: retains OEM MAF and ECU mapping; no remap needed for basic fitment
• Two front ducts + factory inlet path: true 3-path induction - cooler air, sharper throttle response, louder induction note
• Structural benefit: integrated carbon fibre strut brace stiffens the front end - measurable on track day, noticeable in fast road cornering
