Spark Plug

[T.O.Craig]

Howdy to all,
I dropped a spark plug yesterday and the porcelain came out in a bunch of pieces..I'm at home trying to reorder through ACS but I don't have the plug with me. Have a stock IO540A4D5 motor from Vans. If my memory is correct, the champion plug only had e-8 on the side. I think. I did right down a Lycoming part number from the book which was 1182-e7
Could it be a REM38e?
What do we torque the plugs to...?

Found it at ACS
Thanks

Lycoming specifies 35 ft lbs torque for plugs. Use some graphite thread lube, and new or annealed gaskets.

Auto spark plug adapters

Just a note, if you are using auto spark plugs like I do with the Pmags it?s only 18ftlbs of torque. I almost made a mistake and used 35 after switching from aircraft to auto plugs.
