I have always been strongly against Splitfire spark plugs.  Their wires aren't bad, but they're not the best either.  But their plugs... they blow.

Just go with the stock NGK plugs.  Best bang for the buck.  I went to napa and got all 4 of mine for ~$5.  All the product numbers can be found in the owners manual.  There are minimal if any gains to going with a better plug on a stock engine.  If the bug bites you, replace your wires, cap and rotor at the same time if they haven't been done in a long time, if ever.  All those items are about $75 total.

15.9 sounds pretty good on a fouled plug (pretty good in general I think for a mostly stock 240).  I haven't made it out to the track yet, but hope to soon.
