BMP Manifold 1/2 Phenolic Spacer || N54/N55/S55

Precision Raceworks Phenolic Spacer Plate – 0.5" Thermal Insulation Spacer for BMW N54, N55, S55 Engines

Upgrade your engine performance with the Precision Raceworks Phenolic Spacer, a high-quality thermal barrier engineered for serious enthusiasts and professionals. Proudly Made in the USA, this spacer is crafted from premium canvas-based fiber-impregnated phenolic material—one of the best choices for thermal insulation in high-performance engine applications.

✅ Key Benefits of the Precision Raceworks Phenolic Spacer:

• Superior Thermal Insulation: With a Rockwell Hardness rating of 100 and a low thermal conductivity rating of 2.03, this spacer drastically reduces heat transfer between the cylinder head and intake manifold.

• Lower Intake Air Temperatures (IAT): By limiting heat soak, the spacer helps maintain cooler, denser intake air, improving combustion efficiency, reducing knock (detonation), and enhancing power output.

• Optimized for BMW Engines: Compatible with BMW N54, N55, and S55 engines. Specifically designed to work seamlessly with aftermarket aluminum intake manifolds, including all BMP (Black Market Parts) intake manifolds.

• No Stud Extensions Required: Fits many performance manifolds without the need for additional hardware, simplifying your installation.

• Clean Installation with Factory O-Ring Seals: Engineered to reuse factory manifold-spec O-ring seals, eliminating the need for messy gasket adhesives and ensuring a leak-free, airtight fit every time.
