Bosch 0280150431 race rally upgrade injector sets of 4 (these are priced per pack of 4)
These are matched sets of 4 so that when you receive them you are guaranteed these to be within 1% linear deviation of each other, this makes for perfect cylinder balance and no drop in cylinder efficiency because of mismatch or usual manufactures 3-5% deviation. Nobody matches sets like this, only Mr Injector UK.
