BOSCH Injector – Z28 / B284 – 550cc

Z28 / B284L upgrade Bosch 550 CC Multi orafice injectors

We have used these injectors succefully in many tuned Vectra VXRs , with most of the upgrade injectors being a similar price then it makes sense to upgrade to one that has a reasonable size increase. The larger than requires size increase does not cause any harm at all if the ECU is recalibrated correctly then these injectors will work perfectly and fit perfectly too – without any wiring adaptations.

Typically we can istall these prior to ECU calibration on the day , fitting these takes around 2 hours , we also recommend swapping the spark plugs and any suspect ignition coils at the same time. This will not add any further labour time - only parts cost.   If you are interested in a calibration session for your Z28 engine then please get in touch :)
