How much past finger tight to torque plugs?

[vafan13]

How much past finger tight are folks torqueing their spark plugs? Quarter turn?

You want the washer to "crush", it will feel wrong tightening it but quarter turn past finger tight isn't enough. If I had to guess off memory it's probably 1 full revolution from finger tight.

Thanks. Once the washers fully crushed it's not going to crush again, so then what? (Not a rhetorical question)

Tbh idk why they made it like a crush washer, it's just the initial install but as long as the plug isn't fouled your free to reuse it.

There are torque listed for spark plugs and angle (s) past stopping for crush style plugs. Rep pretty much has the jist of it.
