Direct Fit and Runs Like New
This injector assembly fit perfectly on my GMC Jimmy. Came with the bracket, plugged in without any issues, and brought the engine back to life. Idle is smooth, no more hesitation or misfires. If you're having fuel delivery problems, this is a solid replacement option.

Two week honeymoon ends in leak
The media could not be loaded. For the first two weeks or so it worked perfectly then coming home from the store I smelled fuel and then found that the new injector was leaking through the electrical plug not the fuel lines but the electrical plugs that ain't supposed to ever happen.

Great upgrade, SUPER PRICE
Better than rebuilding the original. Please find help if you have never done this. As always it's simple if you know what you are doing.

Defective
For my 1997 Chevy truck. The piece ended up being defective. Now more work and money thanks to this issue.

Plug and play replacement
We popped out the old CFI, popped in this EFI and everything went swimmingly. I can't speak to how long it will last, but I needed my truck to run now and now it does.
