Siemans High Flow Standard Size 690 Blue Injector
Siemans high flow injector, blue 690 (these injectors flow 630cc at 3Bar, they will flow more at higher pressures and can be used up to 7Bar), 12.5 Ohms suitable up to 450bhp in Vauxhall, Duratec & Hayabusa engines. Direct replacement in the standard system. Used on high specification, turbo & super-charged Vauxhall & Duratec engines.
These injectors are sold singly but if you order a set of four, you will receive a set that are flow matched – we insist on this to ensure your engine receives even fuelling across cylinders. Normally charged at an additional cost for flow matched sets of 4, but we do not charge any extra for this service.
