Will fit 5.0 4.6 and 5.4 engines with the Bosch EV1 type injector which was used from the 1990’s thru the mid 2000’s. Kit contains both types of Pintle cap – the shorter 6.25mm height and the longer blue 7.60mm height. We have found that either size pintle cap was utilized depending on the year of the vehicle. Utilizing the proper size pintle cap is important so as to not corrupt the fuel spray pattern.
