Am I right in thinking that the same plug number with -11 at the end are the larger gapped plugs which should be used on new Splitfire coils?

Do I need a torque wrench when installing plugs or can I just hand turn and then tighten?

Cheers

theres instruction as to tightening on the box. of crush washer is now crushed (new) turn it about 200 degrees after it is hand tight. if its already been crushed (tightened adn loosened a few times) about 20-25 degrees.

Not too tight is the answer I think. Changed mine at the weekend... the old ones didn't even need a socket to turn them :shock: but when I put in the new ones, I tightened them as much as I could be hand, then gave them each a third of a turn with the ratchet just to tighten them a little. Felt OK I think.
