First Spark Plug Replacement

[Dave928]

i've used copper anti-seize on every spark plug for the last 30 years. 5 years of that as a dealer tech and 15 as an aircraft tech (not just spark plugs). i've never had a problem (electrical or mechanical) with a lubed plug. they only problems i've seen are from dry plugs. rusted in, pulled threads, you name it.

copper on spark plugs and lug bolts, nickel on O2 sensors. and a little lithium on those o-rings...
