GM Genuine Parts 217-3021 (12608632) Multi-Port Fuel Injector Kit with Fuel Injector, Clip, and Seals

I knew there was one bad injector but no way I was going to tear it apart for only one. Running great, must have been a few others that were weak as well. Running better than I expected after install. Pain to get to, replace the plugs while you have the upper intake off and tape the intake gasket to the upper intake otherwise you will never get it on without damaging the gasket - unless you have the engine out the firewall makes it a challenging job.

Best price and fast delivery

Great product, much cheaper that having the dealership do the repair.

Good quality
