For over 40 years; Cosworth's been leader in innovative multi valve cylinder head design both racing high performance production cars. Cosworth Ported Valve Cylinder head range is latest advancement. Modified from OE cylinder head castings; substantial flow improvements upgraded valve train components offer superior performance your high performance engine.
Each original cylinder head design is carefully evaluated tested to establish improvements required to meet target performance level. Hours of testing flow bench validation used to determine best advanced port design yielding maximum usable power response. However; there is more to cylinder head design than just maximum flow. It is critical that port velocits maintained to ensure drivability valve train components matched to guarantee reliable performance. Once of these factors have been tested validated; final port contour is digitized. Using digitized program; we then reshape both intake exhaust ports using axis mill producing an accurate consistent port shape every time. In addition to reshaping enlarging intake exhaust ports; most Valve Cylinder heads feature a re-shaped combustion chamber to un-shroud valves increasing flow performance. After machining; each cylinder head receives a multiangle high performance valve on precision valve seat cutter. Then each cylinder head is ultrasonically; cleaned; serialized then hand assembled with select high performance valve train components; ready to install on your engine.

For: Subaru WRX Sti YR: 2004-2011 Cyl: 4 App: 2.5L Turbo 6-SHPeed
The versatile FX500 System uses either the Power Plus I or Power Plus II Pressure Plate along with a solid center 4,6 or 8 wing (paddle) Ceramic Button disc. The FX500 disc is designed for outstanding holding capacity and rapid heat dissipation. The FX500 ceramic paddle design creates a quick and rapid engagement as well as clutch chatter that is not recommended for the street. Learn More

For: Subaru Forester YR: 2004-2006 Cyl: 4 App: 2.5L 5-SHPeed 4WD
The FX200 System uses the Power Plus I Pressure Plate and a Steel Backed Kevlar disc. This clutch is designed for the street enthusiast or weekend racer. The FX200 offers similar torque rating and holding capacity as the FX100, however, its life expectancy is increased with the Kevlar disc. Our Kevlar friction material is non-abrasive and doesn't score the mating surfaces. It features only slightly increased pedal pressure, significantly longer life than stock, and normal clutch feel during engagement and disengagement for the smoothest operation of any stage we offer. Minimum 500 Required break in miles. Please see The Technical guide for more details Learn More
