S55 Turbo Blanket for BMW M2 Competition / M3 / M4 (F8x)
Your S55 turbo runs hot — and that heat radiates into the engine bay, raising intake temps and stressing surrounding components. This turbo blanket wraps your S55 turbos in a high-performance thermal barrier, cutting underhood temperatures by up to 90% and protecting everything around it.
Fitment
- BMW M2 Competition F87 with S55 engine (2018–2021)
- BMW M3 F80 with S55 engine (2014–2020)
- BMW M4 F82 / F83 with S55 engine (2014–2020)
Note: Fits the twin-scroll S55 turbos. Not compatible with N55 single-turbo variants (M2 base). Confirm your engine code before ordering.

Installation
- Difficulty: Beginner–Intermediate
- Estimated time: 30–60 minutes per turbo (cold engine only)
- Tools required: Pliers, safety gloves, wire cutters
- Engine must be completely cold before installation
- Important: Blanket will smoke during the first 1–3 heat cycles — this is completely normal as the insulation cures. Ensure good ventilation. Smoke disappears after initial cycles.

Why Fit a Turbo Blanket?
- Reduces intake air temperatures — denser air = more power
- Protects nearby hoses, wiring, and plastic components from heat soak
- Faster turbo spool-up by retaining exhaust gas energy
- Reduces engine bay temperatures for improved reliability
- Particularly effective on track where sustained high loads generate extreme heat
