Didn't nobody never tell you about Aircraft Spark Plug Service in Van Nuys? $75
would have gotten you a complete set of overhauled plugs for a 4-banger. The
drill is to send them your old plugs immediately after the annual and for about
$50 a set they will overhaul YOUR plugs and send them back yellow-tagged. You
then put them on the shelf for NEXT year's annual.

Paid alittle more than half that ($8 ea.) for a six banger from another.
Will get the contact info if anyone is interested. Can't report on how
well they perform (ordered 12) until they arrive, should be here this
coming week...
