I could use some help with this. I have an 06 LJ, found the OEM fuel injectors - 53013690AA. They are crazy expensive, like $70-100 per piece… only replacing because I was investigating a ticking noise and found my fuel injectors have cracks…

Also going to do myself a favor and buy the insulation kit since the PO must have removed it.
DEI insulation kit
I bit the bullet and bought 6 Mopar injectors (they sent single jet which I wanted) from Rock Auto a few weeks ago. Also the DEI kit. No complaints and the DEI kit had no problem installing on my 2006.
Try Precision Auto Injector. Great folks. I bought a balanced set.

Looks like this is my only option on their site. Says rebuilt but also says lifetime warranty
Bosch 3rd Gen 4 Hole Injectors

I didn't think the newer TJs switched injectors...I have a 97...but yeah I guess it makes sense.
Go for it... Precision is a great company.

I guess I'm confused. There's no practical upgrades to Jeep stock fuel injectors. If you get more holes the computer just adjusts.
You might get something if you stroke your block to a 4.7 or upgrade your injectors as long as they're attached to an LS, 5.2 or 5.9. Or maybe incremental gains with a dyno tune.
Precision is a great source for stock injectors.
