Critically Correct..
I went to get a set of plugs for my R.S. Hyundai, they have a ridiculous array of plugs for it. two prong, four prong, Platinum, Irridium, Copper this, wonderful that..
16.00 for a couple of those plugs. EACH...
Hmmmm, so I rang up the dealer. He says Champions come with it, replace em with NGK V-Power. Said the Champ plugs it came with suck, wouldn't hurt to get em out early. Claims when peeps come for the 30K the Champions are a mess, all eroded and cruddy. He thinks they use a lousy heat range for them.
$1.19 each then some discount, got out the door for $3.67..
Nice silvery plug, Resister. Even got the guy to let me gap em to OEM spec with his nice wire gapper tool (never bothered getting one lately, always lost em). Sometimes, I like Advanced. Can't argue the price of the plugs!
Now. IS there a difference in a Dollar plug vs. the 10, 12, or 16 dollar plug? Or is performance the same, and the expensive plugs just LAST longer? My RS recommends 30K, which tells me they want the old plug out of the threads more frequently than other cars..
Surely a Hyundai doesn't stress plugs, other than cheapies?
