Spark plug recomendation for my 4.6
Hi need the right set of plugs for my 1998 GT 4.6L engine. I am in Phoenix AZ and I am detonating or rather just pinging a little under load. I think the proper heat range and right plug may help. Any recomendations?

Really you mean there is no benefit from using an iridium fine wire over standard construction in performance or at least wear/longevity? I don't enjoy pulling plugs (i do on my old cars and reading them) such that if I can get two years out of a set great. I have had my iridiums in my car now for 3 almost 4 years (I know I know). I think Autolite sells XP iridium Xp105 fine wires for like $6.50 which seems reasonable. Comments?

I just spoke with NGK and they recommended the TR6-IX over the TR55-IX plugs as they are the next heat range colder. They said no issues to run these one heat grade colder in terms of mpg or performance. I found a set on ebay for $6.25 per piece. I will see how these run and see if they let me go down a step in fuel grade in the summer.

Oil soaked is not good lol. Does your car use oil? Burn oil? Smoke a little bit? Are you sure they werent fuel soaked and not oil soaked?
