Delphi FJ10594 Fuel Injector

Exact replacement for the existing injectors in a 2006 GMC Envoy SLT 4.2L i6.

Highly upset. So be warned the picture shows the full injector with everything. However, I received mine today. Ordered 4 and when I opened them to my surprise there was no retaining clip. Yes the o-rings were there in new condition, they work well so far. Just wish they had the retaining clips as well.

Firstly, let me tell you that this injector was never installed - I can't speak tot he quality of the product, but it is made by the OEM manufacturer so I don't imagine the quality is too bad. Anyhow, here's why I'm reviewing this product - if you have a Chevy Colorado and are looking to install this injector to remedy a misfire check engine code, BEWARE! For my truck this code (P0302, and occasionally P0300) was caused by failing valve seats. This is a common problem on the Colorados from 2004-2006 and requires installing a new cylinder head. Changing these injectors as a means of diagnosing a misfire issue is a terrible idea... the job is VERY difficult and time consuming, and it won't likely fix your issue. So, my advice is this: save your money, buy a leak down gauge and run a leak down test - if this test fails you'll be very thankful you didn't waste your time and money installing an injector!

Exact fit! Worked perfectly!⭐️⭐️⭐️⭐️⭐️

Injectors are fine,but be aware,unlike the pics, they do not come with the clips, had to purchase them from Rock Auto for another 35 dollars,emailed about them not having the clips like the pic,but never got a reply
