new fuel injectors

Part arrived in a timely manner. Further, I can't believe it is the same vehicle. The power and gas mileage are significantly better. Awesome is the closest word for the change.

Outstanding Results

Summit RacingSummit Racing Verified Purchase

Our 96 Bravada had been getting harder and harder to start, and running rougher and rougher for the past 2 years or so. I replaced the older style 'spider' in about 3 hours, and it now runs even better than like new. This job required no lift, no crawling under, no special tools, and was done with both feet on the ground, at about 1/4 of the $$ my local shop quoted us. ...read more

GREAT VALUE, GREAT FUNCTION!!

Summit RacingSummit Racing Verified Purchase

Bought this for 1998 Blazer 4.3 that was running very rich, stalling, and starting hard due to flooding. Injectors arrived quickly and were easy to install in place of old injection system. Stock bracket was used with no modifications. Routing of injectors was easy - just the way directions stated!! Came with new fuel pressure regulator, but had to buy upper plenum gasket set. Truck fired right up, idled smoothly, no more black smoke out of exhaust, no more codes for oxygen sensors or catalytic converter. Power noticeably improved as well as gas mileage!! Anyone with similar issues on these 4.3 central injection motors would be wise to try this conversion to multiport injection. ...read more
