Tomei 93.5-1.0mm Head Gasket Subaru WRX | STI EJ20 02-07 - TA4070-SB01B

Tomei began operations in 1968 as a race car tuner in Japan. Over the last 40 years, Japan has emerged as one of the leaders in automotive research, racing, and culture. Tomei products have been utilized in nearly every motor sport imaginable. Tomei's racing heritage means their research and design team have first-hand knowledge of the extreme demands racing puts on an engine. Using only the highest quality materials means that Tomei's products can handle the intense strain and heat a purpose-built engine will experience, whether it be on the street or the track. Tomei's attention to detail is second to none. All of their products are thoroughly researched and engineered to achieve optimal efficiency. Because even minuscule differences in measurements can cause catastrophic engine failure, all Tomei products fall within strict tolerances. Tomei machines all of their engine components to enhance airflow and ensure proper fitment and seal.

With the increase in combustion pressure from performance engines in recent years, the burden placed on the head gasket has grown tremendously. To maintain the highest precision possible in a high-performance assembled engine, strict measurements and maximum sealing are required. The right torque values on each head stud and bolt are essential to keep everything together and gain the most out of your engine. When bolts are screwed into place, regardless of the bolt type and strength qualities, the pressure is always on the first three threads of the screw, which takes the most stress. If the cylinder block is badly distorted, then the screw threads can be damaged as well. Stud bolts with dynamic designs allow the screw bolt to take on equal stress on all threads, which will greatly secure maximum sealing pressure for race and airplane engines. Since the cylinder capacity can fluctuate with the thickness of the gasket used, the compression ratio can be adjusted with the gasket's thickness. This thickness will help with the final adjustments to get your setting closest to the target compression ratio.

Stainless steel was chosen as the head gasket material because of its heat conductivity efficiency, which evenly distributes heat and aids with cooling. This will greatly improve reliability and reduce the chances of a blown head gasket.

The natural high tensile qualities of stainless steel greatly increase the joint rigidity of the cylinder head with the cylinder block. This helps minimize the chances of the engine warping under severe stress loads that performance engines undergo when running high power applications. The result is improved durability and added power gains.
