Forge Motorsport recirculation valve for the Fiat 500 Abarth T-Jet made from billet aluminium. This recirculation valve replaces the standard electronic valve. This offers improved throttle response and clamping load to maintain boost pressure more reliably and eliminates the chance of common diaphragm failure. The kit is complete with all fittings and includes a replacement solenoid and wiring harness to activate the valve to retain the engine management functionality. The valve itself is of piston design for longevity with the ability to be serviced and tuned with replacement springs if required. (See below) If you wish to tune this product to fit the needs of your engine, please see the spring tuning kit below. Please note: This product will NOT fit the 2012-on Abarth Multiair engine. 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.
