Set of 6 flow matched 125 lb/hr injectors (Bosch). These are high impedance injectors, so they will work fine with the stock 86/87 Buick ECM, with a matching chip. Great for E85 down to around 10.0's in the 1/4. No more worrying about whether you have a specially modified ECM to run these! These are flow matched. Depending on what car these are used on, you would require a new chip, or ECU programming to work correctly. These are the stock injector length and have the stock EV1 connector, no adapters necessary. Fit fine with stock fuel rails.
