Precision Sealing for High-Performance K-Series Engines The TODA Racing 12251-K20-016 is a high-performance, multi-layer steel (MLS) head gasket designed specifically for the Honda K20A engine. Unlike standard gaskets, the TODA version is engineered to provide a superior seal under high combustion pressures while slightly increasing compression for improved power output.

Why Choose the TODA Metal Head Gasket?

• Optimized Compression: With a thickness of 0.6mm, this gasket is thinner than the standard OEM unit. This effectively reduces combustion chamber volume, resulting in a bump in compression ratio—ideal for maximizing Naturally Aspirated (N/A) horsepower.

• Superior Sealing Power: Constructed from high-grade stainless steel with a specialized coating. This design prevents "blow-by" and coolant leaks, even in high-revving engines frequently seeing 9,000+ RPM.

• Precise Bore Match: Specifically designed for a 86.0mm bore (up to 86.5mm), ensuring a perfect fit for the K20A, K20A2, and K20Z engine blocks without interfering with the combustion path.

• Essential for Engine Builds: Whether you are installing high-lift camshafts or high-compression pistons, this gasket provides the reliability needed for circuit racing and spirited driving.
