Cometic Gasket 2019+ BMW/2020+ Toyota B58TU Gen 2 .071in DST Cyl. Head Gasket - 83mm Bore
The Cometic C14208-071 is a multi-layer steel cylinder head gasket engineered for 2019+ BMW models equipped with the B58TU Gen 2 engine and 2020+ Toyota GR Supra. This .071in thick DST gasket with 83mm bore provides strong clamping force to handle elevated boost and compression levels in performance builds. It maintains integrity across extreme temperatures and pressures for consistent engine operation.
Key Features
- Multi-Layer Steel Construction: Three stainless steel layers with a nitrile fiber core resist blowout and deliver consistent sealing under high cylinder pressures.
- 83mm Bore Size: Precisely matched to B58TU Gen 2 cylinder dimensions for stock rebuilds or mild overbore applications without trimming.
- .071in Thickness: Reduces combustion chamber volume for higher compression ratios while supporting turbocharged power increases.
- DST Sealing Technology: Enhanced bead design around cylinders and ports prevents leaks and coolant crossover in demanding conditions.
- PermaTorque Coating: Rubberized layer on outer edges promotes even torque retention and simplifies installation on aluminum heads.
Product Notes
- Confirm B58TU Gen 2 engine code before purchase as it differs from earlier B58 variants.
- Head and block surfaces must be flat within 0.002in for proper sealing.
- Packaged flat in protective envelope to prevent damage during transit.
Installation Notes
- Professional installation recommended.
- Degrease and check mating surfaces for flatness using straight edge and feeler gauge.
- Use OEM torque sequence and values starting at 22 ft-lbs then final to 70 ft-lbs plus angle.
