Gaskets Fail, Fuel Injectors giving check engine light.
I have not been happy with these fuel injectors. Its been absolute waste of $130 I say $130 because I also had to buy a new set of Gaskets because the ones that came on these fuel injectors do not stay inplace when you put the injectors in. I have had my truck pulled apart like 8 times now chasing a to Rich check engine light I never had prior to swapping my fuel injectors. I have bought a new O2 sensor and a new Mass Airflow sensor, spark plugs are already new. I have no vacuum leaks. So the only thing left here is the fuel injectors themselves. The amount of time and money I have now spent on this job all for 1 miss fire has been insane. But now I will be forced to buy another set of fuel injectors. This is a lot of money to be out all because I cant trust the parts I buy these days.

BEWARE OF SELLAR, and PRODUCT!!!!
Injectors were junk! Here’s the story, my truck had a slight miss before finally just going through and replacing all plugs and wires. Seemed to run just a little better so I changed out the coil packs, no change. Finally I just said “I’ll buy injectors” (As I should have know not to buy cheap injectors) I went on here and got theses. Pulled the old ones and and replaced it with the ones listed, changed all seal and ensure they were properly seated correctly. As I went to start the truck, it seemed like the system needed bleeding. Continue to start it. After starting it over and over it never bleed. I went to start it again only for the truck hit once then lock completely up! After tearing it back apart I found the one injector stuck open firing just to destroy the piston. Beware of this company! Do not make the $5,000 dollar mistake I made.

Fixed my P0219 and P050D codes
was a bit skeptical but decided to take the plunge on these given the huge price difference between OEM injectors and these. I was hesitant to sink a lot of money into my error codes cause a lot of times it seems like you just end up throwing money and chasing problems. Needless to say these worked perfectly. My GMC Sierra 5.3 error codes immediately went away. OEM injectors only lasted less than 60K so even if I get 30K before the codes appear I'll be more than happy

Good customer service
I installed these fuel injectors on a 2015 Chevy Silverado. I did have quite a bit of difficulty getting the fuel rails removed, but everything else went fine. I started the truck after installation and right away had misfire on cylinder 2, a real disappointment! After checking all my work, spark plugs, and coils I just had to assume it was a bad injector. The company did trust me and sent me a new injector right away (which did correct the problem). While I waited for the new injector I pulled the fuel rail out to get ready, and when I did I noticed the Teflon seals at the bottom were out of place and damaged. I ended up pulling the other rail and it was the same story. So this is the real reason I am writing this review. If you do decide to go with these remanufactured injectors, you should also use the seal tool on the Teflon seals to make sure they are sized properly. Just because the seals are installed doesn't mean they are sized. My truck is running fine now, but it was a lot of down time for me and if I had to do it again I would go with new injectors.

If it's too good to be true it is. Figured it couldn't be worse than mine and I was wrong
