[s-cars] Spark plug poll

[Theodore Chen]

i've never had my plugs (F5DPORs) come loose.  i've checked a few times and they're always tight.  i always put some antiseize on the threads when installing them, and i also tighten them by feel rather than with a torque wrench, since my torque wrench doesn't go that low.  i torque them against steadily increasing resistance until i feel a sudden rise in resistance.

When I was still in the UK, I had issues with the F5DPORs coming loose
 but I think I managed to resolve it by tightening the plugs with the
 engine slightly warm though I didn't put in enough miles to confirm this
 once and for all.

My reasoning was that, with the engine warm, the plugs go in easier and
 seat better so when the engine gets hot, they don't tend to back out.
 I don't remember ever having a loose plug problem since then. I think
 they were actually hard to remove.

Try cleaning the threads in the cylinder head then installing the plugs
 with a warm (not hot!) cylinder head.

Oh, I've also switched to NGKs. BKR7Es in there at the moment but am
 switching to Iriway 8s (BKR8EIX) at the next change.
