FUJI Racing 14mm Cylinder Head Studs – Subaru EJ Engine
Designed for the ultimate in engine performance and reliability, Fuji Racing’s 14mm Head Stud Kit is a must have component for any EJ engine build where 500bhp+ power output is expected. It is essential to have the most reliable system for clamping the cylinder heads onto the block assembly to avoid the heads lifting under load at high levels of boost. The Fuji Racing 14mm Head Stud kit provides this peace of mind.
Now used in many engine builds from fast road cars to full on Group A rally cars, the Fuji Racing 14mm Head Stud Kit is used by many engine builders/tuners. Replacing the 11mm Subaru cylinder head bolts with their 14mm precisely manufactured super high tensile, aircraft grade S99 steel stud and nut system offers many advantages when building your engine. With a tensile strength much higher than that of the OEM bolts and the increased stability provided by the Fuji Racing studs larger diameter. When further combined with the more uniform clamping force provided by the stud and nut arrangement, it is clear why so many successful engines run these kits!
