Product Overview
CNC-machined EGR delete block-off plate kit for 1996-2009 Chevrolet Silverado, Suburban, Tahoe, and GMC Sierra/Yukon with 4.3L V6 and 5.7L V8 CPI (Vortec) engines. The CPI engine's EGR system is a known failure point causing carbon-clogged intake passages and rough running. Our precision billet plate provides a permanent, leak-free block-off. For off-road and competition use only.
