Open the hood on an S55 car and the factory intake is the first thing you see. It is also one of the things holding the engine back. The Dinan Carbon Fiber Cold Air Intake for the F80 M3, F82 / F83 M4 and F87 M2 Competition replaces it with a sealed system that feeds the engine cold outside air through a straighter, freer flowing carbon fiber tube.
Dual airboxes about 20% larger than stock hold 30% larger cylindrical filters, and the intake gives the S55 a slightly more audible, sportier tone. It also turns the engine bay into something worth showing off.
Dinan S55 Intake Power Gains: What to Expect
Dinan rates this intake at up to +14 hp at 6000 rpm and +21 lb-ft at 3000 rpm when it is paired with engine tuning, and reports consistent gains over Stage 1 when combined with Stage 2 DINANTRONICS tuning where applicable. On a stock ECU, the main gains are throttle response and sound rather than the full rated number.
