So as some of you know my engine is currently being rebuilt and should be finished tomorrow!!! Issues began after a valve adjustment at a very well known shop. The same shop replaced coilpacks and spark plugs. I've just learned this very well known shop put accord spark plugs in my s2000. Would this cause issues?

Decreased performance and a shorter lasting plug, just make sure the plugs are properly tightened.

I don't know what plug the Accord uses without a search, and there have been many engines over the years in the Accord.

I am willing to bet the heat range is incorrect as the S2000 has colder plugs than other Honda models, so don't use them even if they are the proper size plug.

New plugs are being installed.

If it's a late model Accord --- heat range is 7, like S2000. Other parameters differ:

Once again, be sure to torque the plugs properly. Billman recommends, as I recall, 22 ft ibf but here is a thread on it. Bad things happen if they start to unwind.

Torque setting if for new OEM plugs which have lubricant on the threads. Do NOT add more.
