every second and can withstand acceleration orces o 8500g. Theseone-o-a-kind high perormance orged pistons have been designed and

manuactured using the same methods as our winning Formula 1 pistons.

Piston Features:

Skirt prole & oval technology engineered to increase lie &

perormance Oil and combustion gas control eatures reduce blow-by and oil

consumption Polished crown reduces carbon build-up and relieves stress Patented anti-detonation bands Specially designed under-crown milling that reduces weight while

maintaining strength and durability

Piston RingsCosworth perormance ring sets are designed to meet the demands omodern high perormance engines.

Piston Ring Features:

Higher power output Improved sealing

Lower riction Longer lie

Connecting RodsThis vital link between the piston and power can make all the dierence

when it comes to ensuring engine reliability in all conditions. Trust theCosworth orged connecting rods that utilize high strength steel and

precision machining to exact tolerances.

Head GasketThe Cosworth head gasket is constructed rom stainless steel witha olded stopper layer to ensure superior sealing under the most

demanding conditions. The Cosworth high perormance head gaskets aremanuactured rom pre-coated die cut stainless steel resulting in uniorm

coating distribution while maintaining a consistent shape.

Head Gasket Features:

Pre-coated stainless steel with a 0.25 micron layer o nitrile rubber

ensures consistent distribution o coating with no high or low areas Manuacturing dimensional tolerance o +/-0.001 Die cut manuacturing process ensures smooth edges Folded stopper layer

Thermal Composite GasketThe Cosworth thermal guard composite intake gasket is designed to aid inthe reduction o inlet air temperature by isolating the intake maniold rom

the heat generated by the engines cylinder head.

Thermal Composite Gasket Features:

Reusable with no deormation Precision CNC manuactured Sae with all uel types

Engine BearingThese are one o the most vital components within an engine and are oten

overlooked when considering high perormance upgrades. Cosworthsperormance engineered bearings generate less heat than normal

bearings by reducing riction.Engine Bearing Features

Specially treated bearing surace or better oil control and less riction Hardened steel backing on all connecting rod bearings

Tight consistent wall tolerances

CamshatCosworth has been engineering camshats or nearly 50 years. Thatcoupled with years o innovative multi valve cylinder head design ensures

our camshat designs are the most efcient in providing maximum usablepower across the widest power band.
