22R Carbureted Emissons Block-Off Kit
Restore performance and simplify your engine bay with the LCE Emissions Block-Off Kit. Over time, aging emissions control systems can become clogged or fail, robbing your 22R of power and causing inconsistent idling or driveability issues.
Designed specifically for off-road and competition use, this comprehensive kit provides everything needed to fully "de-smog" your engine. In addition to exhaust and EGR deletes, this kit includes specialized plates to block off water lines at the timing cover, the center of the cylinder head, and the intake manifold—perfect for builders looking to bypass the heater core or simplify the cooling system.
