Manifold torque

Does anyone know the torque for intake manifold to cylinder head bolts.

Don't .. You will snap an ear off.. Just snug. I use a 1/4" ratchet with an extension and a swivel socket and just snug them up. Then check for leaks and done. Trust me or you will be sending me the intake for welding..

Hmm,

15.5 ft lbs, replace the thin M8 washers with Porsches update, an M8 that's much thicker, 12x 999-025-152-02. If you're doing an intake reseal, or fuel line replacement, I also recommend replacing the six insulator plates.

What is the benefit of the thicker washers?

Probably less distortion under the applied torque and more even distribution of that torque
