Longest lasting spark plugs

Okay, who makes the longest lasting spark plugs? I've got one of those vehicles with hard to reach plugs and I don't want to change them every 30,000 or 50,000 miles.

What do the cars use that boast of 100,000 miles between tune ups?

    Bosch Platinum and AC Delco Platinum have given me excellent results. Expensive though.

    dont know the answer to your question as my pickups are diesel..... i'd rather change glowplugs than sparkplugs. i do have an intrepid that fars as i know had the original plugs in it when i changed then at 140,000 miles they where just about all used up dont remember what it had in it our what i put in.

    I went to look and see where the plugs were on my Ford F-150 2002 with the 4.6L V-8 and I couldn't see them anywhere. Tuneup is at 100,000 miles- maybe I'll find them by then.
    I've always used AC Delco- those fancy high dollar plugs don't do any better.

    I use Bosch platinum tip and change them at 50,000(they could go considerably longer, I suppose). They don't cost that much. A standard plug's electrode protrudes from its insulator and over time begins to melt away, increasing the gap. The Bosch's is flush with the insulator, and remains that way -from what I've seen. And I've changed them a few times, so I'm not entirely ignorant(Others around here can probably help more, though).

    Daddo: Those new Ford V-8 engines, and most all new engines I guess, don't have conventional plugs anymore. Or a coil, or distributor, or plug wires. They have ignitors for each cylinder and the coil is incorporated in with the plug. They just have light-gauge wire running to each cylinder's ignitor. There's something basically anti-American about a vehicle without a distributor cap and plug wires.

    I use Accel platinum plugs in my Jeep and my Harley.

    judge dread- now that I'm 48, I may beleive that, but if I were 18, I may not. Carbon won't build up? If you have a bad cylinder- is the lifetime still good? One can't expect a part to do well with other bad components. An oil burner will foul a new/good plug in miles- no?

    Just changed a distibutor on a 96 Chevy S-10 V-6. It was easy! Takes hours longer to change the damn plugs.
