Wrong Spark Plugs
So I guess I wasn't paying attention when I ordered my plugs, and accidentally ordered the SP-479 plugs for the 5.4 when I should have ordered the SP-493 for my 4.6
I didn't realize this, of course, until AFTER I'd completed the full tune-up. Grrr.
So anyways, the plugs installed properly it seems, the truck runs like a champ, but what impacts may this have in the near/distant future? Is it crucial I get those out and the right ones in immediately? As best I can tell at least from basic "details" at the big box sites, the 479 have a Heat Range of 2 and the 493 a Heat Range of 3..other than that they seem very similar?
Any help appreciated...
