Description
Product Overview
The COMETIC C4313-030 head gasket is a high‑precision component designed for the 2.0L VTEC engines found in Acura RSX (2002‑2007) and Type‑R models K20A1, K20A2, K20A3, and K24. Constructed from a .030 inch multi‑layer steel (MLS) stack, it offers superior sealing capability, heat resistance, and durability compared to traditional composite gaskets. The gasket matches the 89 mm bore specifications and conforms to OEM dimensions (17.5 x 8.5 x 0.3 in), ensuring a perfect fit without modification. Weighing only 8 oz, it is lightweight yet robust, supporting high compression ratios and aggressive tuning.
Usage
Designed for both professional mechanics and dedicated enthusiasts, this gasket excels in engine rebuilds, performance upgrades, and routine maintenance. It is ideal for street‑driven RSX owners seeking reliability, as well as track‑day racers demanding consistent compression and heat dissipation. Installation requires standard torque specifications; no special tools are needed beyond a torque wrench and proper cleaning of mating surfaces.

FAQ
Is this gasket compatible with the 2005 Acura RSX?
Yes, the C4313-030 is specifically engineered for the 2002‑2007 Acura RSX models equipped with the K20A1/A2/A3 engines.
Do I need to replace the head bolts when installing this gasket?
While not mandatory, it is recommended to use new torque‑to‑yield head bolts or re‑torque existing bolts to the manufacturer’s specifications for optimal sealing.
Can this gasket be used for a turbo‑charged build?
The MLS construction handles increased pressure and heat, making it suitable for mild to moderate boost applications when installed correctly.
What torque sequence should I follow?
Follow the OEM torque sequence: start from the center, work outward in a criss‑cross pattern, and finish with the final torque pass as specified in the service manual.
Is the gasket reusable if I need to remove the head again?
MLS gaskets are not designed for reuse. For best results and to avoid compression set, replace the gasket each time the head is removed.
