2016–2021 Honda Civic 1.5T Turbo Gasket Kit

FITS:

• 10th Gen Honda Civic 
• 10th Gen Honda Civic Si

If you’re replacing or upgrading the turbo on your 10th generation Civic 1.5T, this is the kit you want on the bench before the install begins.

This PRL Motorsports Turbo Gasket Kit was developed specifically for 2016–2021 Honda Civic 1.5T owners performing a turbo swap. Whether you’re installing a factory replacement turbo, a PRL turbocharger, or another aftermarket unit, this complete hardware and gasket package provides everything needed for a proper drop-in installation.

Our engineering team reverse engineered the OEM components to ensure precise fitment and sealing while dramatically reducing cost. Purchasing all of these pieces individually through OEM channels can exceed $246, while this single kit consolidates every required sealing component and piece of hardware into one organized solution. It eliminates last-minute parts runs, prevents reusing worn hardware, and helps ensure the turbo install is completed correctly the first time.

This kit will also be included with upcoming PRL 10th Gen Civic turbocharger releases.
