This valve is for the 1.0 Ecoflex petrol engine found in the Vauxhall Corsa. It is recommended for any vehicle where the boost pressure has or is going to be increased by an ECU software upgrade,

Our alternative is a fully engineered solution, offering significantly improved reliability. Our valve and installation kit replaces the original unit with a pressure/vacuum operated piston valve, that still also retains the desirable OEM ECU control over valve actuation. This product has been thoroughly designed and tested with the expressed intent of offering improved valve response and maintaining ECU control while resulting in absolutely NO fault codes, NO check engine lights, and no adverse effects of any kind.

All of the necessary components and detailed instructions are included and everything is designed to make installation as simple as possible.
