Great Price, Delivered FAST!!
Everything about the order was great. They come without the clip that holds them to the Fuel Rail though. It didn't say they were sending them in the order... but wouidn't you know it, I lost several and cannot seem to find them anywhere online. They fit pretty tightly so their purpose may be unnecessary since they can't come out of where they're put into the fuel rail and the intake manifold. Maybe they're irrelevant... Not sure where to get them or what they're called other than maybe Injector metal clips. Aside from that, everything was great.

By far exceeded my expectations!
1A aftermarket injectors.... $700 cheaper than OEM and the quality is more than what I expected. No problems with installation. After almost 3 weeks of hard driving I've had no issues at all. I just had to remove them again to install new knock sensors. Definitely exceeded my expectations! Write your review here. It must be at least 50 characters long. Consider whether you would recommend this product and what you like or dislike about it.

8 pkg fuel injector kit 1AEEK00745
they look brand new, made in china. they are of the new 4 pin hole design. I think my 2004 avalanche is of the 2 pin hole design. I have not put them in yet. Keeping them handy for the day. My truck has 215,000 miles on it.

Not compatible with gmc 2005 sierra 5.3L V8
Not an OEM replacement. Form and Fit, but not FUNCTION.
These injectors have 4 ports at the bottom, not 2 as seen on the 2 website pics. So the sysytem runs extremely rich to the point you get check engine codes for system too rich. I tried resetting the computer, it didnt help.
1AAuto was very good about the return, but fact is i cannot recommend these as a true OEM replacement.

The injectors showed up within a couple of days as expected. They fit without a problem however they don't come with new clips . The fact that they don't come with new clips is my only complaint and it's because I was delayed a day from fixing my truck because I can only get the clips from the dealer . However I would still recommend to a friend.

Very Disappointed
I bought my first item from 1A auto because of the great videos you guys do online. It was a replacement mirror and it it looked just like the OEM mirror and it was cheaper than the OEM price. I appreciate that because my car is at 200k, so any cost savings is great. These injectors were disappointing though and it kind of bummed me out because I thought I had found a great source for online parts. I decided to replace my injectors as part of a 200K service since a bad injector can ruin the 6.0L Yukon motor. They made my truck run rich and start throwing misfire codes. I replaced the ones that were throwing misfire codes with AC Delco injectors. Once I replaced the 4th injector, I just pulled them all. $1200 later plus the cost of the 1A injectors and a ton of my time, no more problem. You cannot sell these if they do not adequately replace the OEM injectors.

Fuel injectors bad
When i received the fuel injectors, I installed them and my motor got even worse. My original fuel injectors have 2 escape holes and the one i bought from you has 4 and I think it was giving to much gas.
