FUJI Racing 14/12mm Cylinder Head Studs & Gaskets – Subaru EJ Engine
ULTIMATE PERFORMANCE
Designed for the ultimate in engine performance and reliability, Fuji Racing’s 14mm/12mm Head Stud Kit is a must have component for any EJ engine build where 450bhp+ 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 14/12mm Head Stud kit provides this peace of mind and cuts out the expense of cylinder head modification.
Unlike Standard gaskets, Fuji Racing Gaskets have the ”folded stopper layer” This design reduces any chance of pressure leakage from the cylinders.
Along with the stopper layer, their gaskets also have a nitrile coating to help seal against the block & cylinder faces
Fuji Racing gaskets are stamped from dies instead of laser-cut, this helps reduce variations between each head gasket during the manufacturing process.
The gaskets are designed to fit 11mm to 14mm head bolts / studs without the need of reeming the centre gasket holes out.
RELIABILITY
Now used in many engine builds from fast road cars to full on Group A rally cars. The Fuji Racing 14/12mm Head Stud Kit is used by many engine builders/tuners.
Replacing the 11mm Subaru cylinder head bolts with their 14/12mm 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’s clear why so many successful engines run these kits!
Spec:
- Manufactured from certified S99
- Tensile strength between 180,000 and 210,000 psi ( MPa: 1230 – 1420 )

As with every FUJI Racing product; performance, precision, and aesthetics are just some of the key ingredients focused on when developing new products.
Die Cutting gives the finished edges for superior opposed to laser cut steel.
