after install we went on road trip for 9hrs out and 9hrs back no missfires .. i was hesitant but bought it and when i pulled out of box it looked good.. this is the updated set

On two occasions I received defective parts one being an actual use not new but used part greasy 30 and so disappointing I do not recommend this company stay away save your money and spend it elsewhere. Like holds true look at the products reviews....

Awesome upgrade to my 1st gen 5.7 Vortec. No noticeable difference in power or mileage. 800 miles so far with no issues

Tubing is shorter than OEM. In order to install the tubing, they are stretched to their limits. The injector collector is extremely hard to seat flush with the top of the manifold housing due to the shorter injector tubing. Random misfiring when diagnosed. The stressed tubing is prone to kinks. It lasted less than a year.

Good fit. 2k miles and no issues.

This product is to be used to fix my granddaughters car. It arrived in a very timely manner. It also contained everything that was supposed to be in it.

The #1 injector did not pulse at all and instead was stuck wide open making it defective and useless. Shame on me I guess.

Injector quit working 2 days after being installed...would not recommend

Installed it on my 5.7 vortex and it just leaked gas right out the bottom of it and locked up my motor had to take out my spark plugs to let out the gas from the cylinders so ALWAYS try it before putting on the plenum to see if part is detected.. I thought the gas came out the Fuel pressure regulator so bought a new one but was wrong
