Complete TBI Throttle Body Gasket Seal Kit for 1985-1997 Chevy GMC Truck Van SUV 4.3L 5.0L 5.7L V6 V8 | O-Rings, Base Gasket & Regulator Seals | Replaces 219-607, 1704
COMPLETE SEAL KIT — EVERY GASKET & O-RING YOU NEED: Includes throttle body-to-manifold base gasket, fuel meter body gasket, upper and lower injector O-rings, fuel line inlet/outlet O-rings, and regulator diaphragm seals. One kit covers the full TBI rebuild.
ELIMINATES VACUUM LEAKS THAT CAUSE HIGH IDLE & ROUGH RUNNING: Aged, heat-cycled gaskets are the #1 cause of erratic idle and poor fuel economy on GM TBI trucks. The speed-density ECM cannot compensate for unmetered air entering through failed seals — this kit seals every potential leak point
DIRECT FIT — COVERS V6 AND V8 TBI ENGINES 1985-1997: Fits Chevrolet and GMC C/K pickups, Suburban, Tahoe, Yukon, Blazer, Jimmy, R/V trucks, G/P vans, S10/S15, Astro/Safari, Camaro, Caprice, Cadillac Brougham/Fleetwood, Buick Roadmaster, and Isuzu NPR.
OE-SPEC MATERIALS — BUILT TO HANDLE THERMAL CYCLING: Engineered rubber O-rings and precision-cut paper gaskets withstand the extreme heat cycling between the aluminum throttle body and cast-iron manifold that destroys cheap universal gaskets.
