Product Description

The Cometic PRO2041T is a comprehensive StreetPro top end gasket kit designed for the Toyota 4A-GE 1.6-liter DOHC 16-valve inline 4-cylinder engine used in the 1984-1992 Toyota Corolla GT-S (AE86 and AE92), 1985-1989 Toyota MR2 (AW11), 1988 Toyota MR2 Supercharged (4A-GZE), and 1990-1992 Geo Prizm GSi. This kit includes everything needed for a complete top end rebuild, centered around a .040" MLS (Multi-Layer Steel) cylinder head gasket at the stock 81mm bore diameter. The kit also includes valve cover gaskets, intake and exhaust manifold gaskets, cam seals, valve stem seals, and a thermostat gasket set.

The Toyota 4A-GE is one of the most celebrated engines in Japanese automotive history, powering the legendary AE86 Corolla GT-S and the first-generation MR2. It remains a highly sought-after platform for enthusiasts, with a strong aftermarket supporting naturally aspirated, turbocharged, and supercharged builds. The PRO2041T provides race-proven Cometic sealing technology in an affordable, comprehensive package that eliminates the need to source individual gaskets from multiple suppliers, ensuring that every sealing surface in the top end is covered with quality materials.

Cometic StreetPro top end kits are designed to include all necessary gaskets and seals for a top end rebuild. Installation of the MLS head gasket requires clean, debris-free mating surfaces with a recommended surface finish of 50 RA or finer - no supplemental sealants should be applied to the head gasket. This kit fits the 16-valve 4A-GE only - the later 20-valve 4A-GE (Silver Top and Black Top) uses a different head casting and requires a different gasket kit. For overbored applications, the PRO2041T is available with 81.5mm and 82mm bore head gaskets using the appropriate bore/thickness suffix (e.g., PRO2041T-815-040 or PRO2041T-82-040).
