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.

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.
