Summit Racing™ Direct-Fit TBI Fuel Injector Wire Grommets

Summit Racing™ direct-fit TBI fuel injector wire grommets are factory-correct replacement seals designed for General Motors throttle body injection systems. They securely seal the electrical wiring harness where it passes through the throttle body housing. These grommets serve several vital functions for your engine:

* Seal Vacuum Leaks: They prevent unmetered air from being sucked into the intake, which could otherwise cause rough idling and poor engine performance.
* Protect the Wiring: By holding the wires tightly, they shield the delicate injector harness from harsh under-hood temperatures, oil, and chafing against sharp metal edges.
* Restore Reliability: Original factory grommets are notorious for hardening, cracking, shrinking, or deteriorating over time. These replacements restore the seal and prevent shorts.

The grommets are manufactured to exact original equipment specifications from high-quality, oil-resistant materials like thermoplastic elastomer or rubber, ensuring they perfectly match the correct wire-hole configuration (usually a 2-hole or 4-hole design) for specific GM models.
