                               I checked that site and checked plugs for my 02 Chev and one brand came up as $24.95 per plug.  $200 a set is just a little rich for my blood

i did a search for my 04 and came up with probably the same brand for 24.95 EACH

clicked on the link and came up with this

Pulstar Pulse Plug

Pulse plugs are the latest in performance ignition technology. They are essentially a spark plug with an internal pulse circuit which increases peak spark current by up to 20,000 times as compared to a traditional spark plug. Their physical dimensions are the same as your stock spark plug. But this is where the similarity ends. Pulse plugs incorporate a pulse circuit, which stores incoming electrical energy from the ignition system and releases it in a powerful pulse of power. Instead of 50 watts of peak power, typical of a spark plug, pulse plugs deliver up to 1,000,000 watts of peak power. This allows Pulstar Pulse Plugs to burn fuel more efficiently than traditional spark plugs. Pulstar plugs generate a much larger spark than spark plugs and at twice the speed. This faster ignition generates more power you will feel in a livelier throttle response, more horse power to the wheels and increased gas mileage.

yes those are the ones. Slick you say your truck doesn't idle as well What about the claim for power and mileage?

My 02 is a 2500HD with an 8.1. I bought it new and have around 82,000 on it. It's done everything I ever asked of it. Including pulling our 30  ft travel trailer over the Rockies on I-70 at speed rather than crawling up. The platinum seem to work fine. No problem off idle it'll turn the tires fine

82k and you put plugs in it!?!?
they're good for a 100k+ before you need plugs
and many tanks of gas;)


what're you getting for milage?
the bosses 8.1 don't get any (milage)
his son'e 6.0 ain't much better but the ARE both X cab 4x4 2500hd's...

I replaced the plugs at about 70,000 before I left for my western parts hunting trip last spring. The very best I've ever gotten was 15mpg usually around 13mpg this is running empty. Pulling our travel trailer 7-8 1/2mpg, pulling the car trailer 10mpg. You're right about the 6.0L my son had a 6.0L  identical truck to mine except for motor/trans, both ext, 4wd, 2500HD. Didn't really see any better than my 8.0 and of course didn't have the guts mine does for pulling. In 06 he traded it on a new Duramax because the 6.0 wouldn't do the job he wanted pulling his 24" enclosed
