• CNC machined sensor housing in the OEM position for correct readings and factory manners
• Tough black powder‑coat finish for a clean OEM+ look under the bonnet
• Typical increases of 12 to 20 HP without a remap

How it feels

Expect crisper throttle pick‑up, stronger mid‑range pull and a deep turbo intake note when you lean on it. Calm and civil in normal driving, purposeful when you want performance. No software required.

Why enthusiasts choose this kit

The oversized filter and straight 4 inch alloy pipe minimise restriction to the turbo for improved response and measurable power gains. The airflow meter sits exactly where BMW intended, so idle quality and part‑throttle manners remain smooth. It looks right, fits right and performs brilliantly.
