OVERSIZED VALVES

The oversized head diameter is designed specifically for each application, significantly improving the flow rate.

WAISTED STEM

The waisted stem allows a greater volume of air/gases to enter and exit the combustion chamber as the valve extend.

ENGINE SPECIFIC DESIGN

Each valve is designed and precision machined specifically for the intended engine/application.The head, face, stem and lock groove designs have also been optimized to enhance sealing performance, efficiency and durability.

HEAT RESISTANCE & DURABILITY

• INTAKE - SUH35 HEAT RESISTANT STEEL with SPECIALLY FORMULATED COATING.

- The intake valves are made using SUH35 HEAT RESISTANT STEEL which is more commonly used to make exhaust valves. These are then coated with a special formula that further improves the valves' resistance to heat, wear and corrosion.

• EXHAUST - INCONEL 751 ALLOY

- In order to withstand temperatures of up to around 1000?, the exhaust valves are made using a nickel based heat resistant alloy, INCONEL 751.

IN&EX COMPLETE SET

Although sold as an IN&EX complete set, each valve can also be purchased individually.
