Product Description

The Cometic C4522-030 is a high-performance head gasket built for the 1.6 L DOHC D-series (D16A1 / ZC) engines used in 1986-89 Honda/Acura Integra models. With a 75.5 mm bore and a .030-inch compressed thickness, it delivers excellent sealing under high combustion pressures while maintaining proper head-to-block clearance. The three-layer MLS construction, along with Viton-coated outer layers, offers durability against heat, warping, and corrosion - critical for both rebuilt motors and those pushed harder in performance applications.

This gasket is ideal for enthusiasts restoring factory performance, doing mild performance upgrades, or maintaining reliability in aging engines. Installation demands a flat, clean head surface, proper torque sequence, and specification adherence - given the .030-inch thickness, surfaces must be prepared especially well. Because this gasket doesn't require orientation, fitting is more straightforward.
