I was curious if anyone knows the differences between the fuel injectors in the 3.2l vs the 3.6l Pentastar. I had one fail (I believe) on my 2016 V6 with about 88k miles. The 3.6l parts are $25-$35. The ones in the 3.2 are $128! I also believe the new 3.6 uses an “upgraded” injector, but assume it wouldn’t work on our engines? Thanks for any and all help.

3.2 injector, part # 4627794AA

Go to moparonlineparts.com or your local Jeep dealer, give them your VIN and they will give your the correct fuel injector part number.
I have been driving fuel injected vehicles for 50 years and never needed a new fuel injector.

I have the same question. Looking for an answer as well. Mine is 2014 Cherokee 3.2 V6 and I think our cars use the same fuel injectors
Hi @2014cherokeelimited , good question and one that comes up every now and then. Some of the Cherokee 3.2 injectors run upwards of $100 whereas the Grand Cherokee are like $30! What's that about???? :unsure:

While I don't know the specific differences (I've never had both in my hands to examine them in detail - their dimensions, ohms across the leads etc.) I can say that my recommendation would be absolutely get the ones for your Cherokee based on the VIN. Pretty much every story of someone using an alternate injector ends with a CEL and Pxxx code for fuel/air ratio or similar on the cylinder with the different injector. The ONLY exception I've heard of is that Napa Parts does offer an aftermarket injector that's about $20 less than the dealer and it seems to work fine as a replacement but for the minimal price difference, I'd go with the Mopar.

A couple things:

1. Shop around. For example, for a 2014 it can be had on some Mopar online parts sites for $88.

2. One reason the Grand Cherokee may be different is that the 3.6 got an enhancement in 2016 with upgraded injectors, a cooled EGR, variable valve lift and a bunch of other changes etc. It lost its flex-fuel capability in the process. A bunch of differences from our Cherokees so that injector is different because the engine itself is significantly different.

3. Definitely choose your model/year and preferably VIN. You'll notice for example, even for the 3.2 Cherokee, the 2018+ injectors have a different part number.
