What socket size do I need?

you will need a 5/8th spark plug socket,3/8th drive ratchet and extension over 8".

are these pre-gapped?? do they last much longer than non-laser iridium?

Spark plugs are pre-gapped but you should always check with a spark plug gap tool. The laser is designed to last 80 to 100 thousand miles whereas the non-laser 40 to 60. NGK are the best for Honda.

This is the price for 1 piece. If you have a 4 cylinder car you need to order qty 4, for a 6 cylinder qty 6.
