Skunk2 Spring-Type Lost Motion Assembly Kit - Honda/Acura B-Series VTEC

Skunk2's Lost Motion Assembly kit replaces the factory piston-style LMA in Honda B-series DOHC VTEC engines (B16A, B17A, B18C) with an improved spring-type design that resists the seizing and rocker rattle common when contaminants foul the OEM piston. Each chrome-silicone steel spring uses a hardened tip for durability and is intended for camshaft lift above 0.490 in. Sold as a set of 8.
