Honda K20C1/C4 Down Pipe Gasket 18234-RPY-G02

Honda K20C1/C4 Down Pipe Exhaust Gasket, CV2, FK8, FL5, DE5

This is the OEM Honda downpipe gasket for K20C1 and K20C4 cars, part number 18234-RPY-G02. It uses multi layer steel construction, so it takes heat cycles and boost without turning into a crispy leak generator. If you have an exhaust tick at the turbo flange, slow spool, or that lovely exhaust smell in the bay, this gasket is the first thing we check. We still run these exact OEM style gaskets on our own cars because chasing a tiny leak at the downpipe is not a fun hobby.

This gasket covers what people search for under a bunch of names, Acura Integra downpipe seal, Acura Integra Type S exhaust gasket, Acura RDX exhaust gasket, Acura RDX turbo seal, Acura TLX exhaust seal, Acura TLX turbo gasket, Honda Accord 2.0T downpipe gasket, Honda Accord turbo seal, Honda Civic turbo gasket, Honda Civic Type R gasket, Honda K20C1 down pipe gasket, Honda K20C4 down pipe gasket, performance K20C4 gasket, and replacement K20C1 exhaust gasket. Same job, same spot, it seals the downpipe to the turbocharger or exhaust manifold flange so your turbo stays efficient and your O2 readings stay honest.

Fitment includes 2018 to 2022 Honda Accord 2.0T, 2017 to 2021 Civic Type R FK8, 2023 plus Civic Type R FL5, 2024 plus Acura Integra Type S DE5, 2019 to 2024 Acura RDX, and 2021 to 2023 Acura TLX. It installs like a direct replacement. Clean the mating surfaces, check for warped flanges, and torque it correctly. If your downpipe or turbo flange is rough, no gasket will save you, but a fresh MLS gasket gives you the best shot at a dry, quiet seal.
