well made injectors look sturdy

Decent quality set of injectors at a budget priceI bought this set to replace the original {injectors iny 2004 Xterra's VG33E engine that had a bad stumble at idle.When they were first installed, one initially failed to operate properly and bled sending a ritch mixture out the exhaust. I was gutted, thinking that I had made a bigistake buying this set. I was about to return them but decided to run the engine a few days later and was pleasantly surprised to hear the engine come to life with a smoothe idle and clean exhaust smell. The injectors are not lubricated at manufacture and one was probably partially sticking. The fuel apparently freed it and now the engine runs properly. It is now at about 200 miles with no issues. They are still new)and I will do an update on about 2 months. By then they should have miles on them. Be aware that they don't come with the lower seals that fit into the manifold

Truck runs like new. Has 234,000 miles and you can’t put your hands on it and feel it running.

At first injectors worked great. After 20 miles on injector stuck open causing misfire had to change it out with another one. There does not seem to be anyway to get a replacement for faulty product.

It's ok for the price
