DONT, BUY I REPEAT DON'T WASTE YOUR MONEY ON THESE!! If there was a no star review option, I would use it. I bought these about months ago and it ran well for 2 months then my truck started smoking really bad and leaking gas out the muffler. I spent countless hours trying to figure it out and was clueless. it couldn't be the brand-new injectors, right? took it to the shop and they said it was the PCM because everything else that it could be, was all brand new. I bought a new PCM it did the same thing. After weeks of buying and waiting for the parts I thought hmm maybe I'll look up the injector I bought and look at the reviews and it gave the idea that the injectors could have failed. I went to the parts store and spent 700 on new injectors. and BOOM there was the problem all along. the brand spanking new injectors that I just put in failed. Thank you so much for wasting my time and money.
