We recommend servicing your valve every 3 years, or 20,000 miles, whichever comes sooner
The Forge Supersize valve has been specifically designed and engineered to offer extreme flow rate capability, where only the largest valve will do.
Often when engines have been tuned by installing larger turbo's, software upgrades, and many other boost increasing modifications, improved turbo response can be achieved by fitting the Industry leading Forge Supersize valve, which has the advantage of a greater internal mass air flow specification, utilising an amazing 50mm (2") internal bore, and an aerodynamic piston to direct the air through the large 40mm inlet and discharge ports (1 5/8").
- The Forge Supersize valve can be used on Turbo charged or Super charged applications
- CNC machined piston for optimal flow velocity.
- Solid works generation of enhanced internal piston design, allowing for optimum flow characteristics.
- The Supersize valve utilises Viton O Rings, this material has a very high resistance to temperature and engine vapours.
- The Supersize valve is guaranteed for life.
- Internal service kit available.
- The highest flowing, largest displacement valve on the market.
- Engineered for Performance
Available in machined alloy finish.
Please note: Where the standard valve fitted to your car was electronic (solenoid operated) the solenoid cannot be disconnected without causing a check engine light. This valve is designed to replace existing vacuum operated valves.

All Forge Motorsport products come with a limited lifetime warranty. All warranty claims must be accompanied by the original proof of purchase to enable us to help you. Failure to supply this proof will result in your claim or enquiry being denied.

Do not use aggressive (acidic) car cleaning products, particularly traffic film remover solutions or shampoos to clean your intercooler, radiator or oil cooler. The use of these products can damage Forge Motorsport cooling systems and invalidate your warranty. These are often found at car washes. A light, warm, soapy solution (free of harsh acidic cleaning compounds) should be used to clean you cooler and thoroughly rinsed away. We recommend that you should inspect your product on a regular basis for bent and/or crushed fins. Any bent fins should be carefully straightened to allow ambient air to pass through the core face. At the time of installing your Forge radiator, an approved coolant must be used and added to the coolant system. Be sure you never mix coolant and always use distilled water.
