Upgraded 4 Holes Gas Fuel Injectors Fit For GMC: Yukon (XL)/Sierra, 1500 2500 3500, For Chevy: Tahoe/Express/Suburban/Silverado, For Cadi Escalade, V8 4.8L/5.3L/6.0L 2000-2006# 17113553(8 Pcs)

Worked like they should... Great value for the money

Solid injectors, no issues with install work great.

These triggered my vehicle ECU as faulty , setting the mis fire code

One injector was bad , had to reuse an old one they sent replacements. And handled it efficiently and expeditiously

Installed in my ‘05 Yukon Denali 6.0 and what a difference they made. Runs so much better than before. Cut and dry install on the LS engine just remember to use a little lube on the O-rings for easy installation of the injectors and to relieve the fuel pressure before removing.

7 out of 8 of these injectors works great. The 8th injector misfires. Can't find out if I can purchase a single injector to replace.

100 real 🫡✌️

Be sure to check your vehicle if it needs 4 ports for the injection. This upgrade caused rich conditions and caused P0172 and P0175 for both banks.
