One of the easiest modifications on the 2.5/4.0/4.7 is a fuel injector swap. Jeep originally used 1-hole pintles on their injectors. However, Chrysler used 4-hole pintle injectors on everything else. The 4-hole pintle provides a more even fuel spray pattern, giving better atomization, making your engine work less and run smoother. Each re-manufactured set is flow-tested and lubricated, and come with a 12-month warranty. We do not recommend changing injectors on 2005-2006 models, due to different flow rates.

So, if you are supercharging your Jeep (2004 or older), installing a set of these certainly won’t hurt!

Look at your current injectors to determine if you have an EV1 or EV6 connector:

Bosch EV1: ev1     Bosch EV6: ev6
