  • Fits 2015 Yukon XL Denali
Size: 1 FIR + 1 IH + 1 Rail Press Sensor
Works great and was OE. Label on the rail was correct and wire harness good. Make sure you replace the harness if you order a rail without one. These get brittle and the wire insulation with fall apart causing drivability issues.

  • The Injectors were used not new.
Size: 1 FIR + 1 Rail Press Sensor
The rail label was scratched, and the bolts had dirt on them. There was also a yellowish gunk on the threaded inlet port of the rail, and the injectors appeared to be slightly machined at the end that connects to the head. Additionally, there was a slimy residue on the outside of the rail. It looked like the seller may have replaced the seals on the returned injectors and resold them as new. I've purchased injectors from this seller before, and their quality has been inconsistent. The last set of Bank 1 injectors I bought failed within six months. Now, cylinders 1 and 3 are reading low 20 PSI, and cylinders 5 and 7 are showing 38 PSI. The injector drop is much higher than 20%. I wish they would replace the set I bought in June, but they won’t. So, I ordered this new set, only to find they are used. While the price is good, it’s not worth it if the parts don’t function properly. The cost of replacing these injectors every six months will end up being much higher than what you save upfront. Overall, I’m pretty disappointed. ... show more

  • Fit my 2014 chevrolet silverado 1500
Size: 1 IH
Great product.. it is a little pricey but out there in the market it’s more expensive. So it is worth buying it.

  • The vehicle fitment list is wrong - It does fit!
Size: 1 FIR + 1 Rail Press Sensor
As of writing Amazon says this won't work with a 2016 Yukon XL Denali (6.2L). It does! Direct plug and play. Also comes in handy because you're not supposed to reuse the fuel pressure sensor. Saves me the headache of trying to find and install one to spec.

Defective parts they wouldn't return my money. Then, when they did, they charge me a $150 to restock them, they are complete rip-off. Do not buy.
