what are some good brands as far as ignition wires and spark plugs. people on here like ac delco and OEM, but if OEM was so great i wouldn't be having to buy new ones.

Do you have to buy new tires? Change your oil? Buy new clothes? Buy anything ever again? Yes, so just because your Delco plugs have worn out doesn't mean they aren't good.

i understand that but when i only get 70k out of a set of wires and plugs why stick with them. i'm looking for something that will give me more life and these plugs are roasted.

your smoking crack, i know people still running the ac delco plugs and wires at 200k with zero problems....i used mine til 100k and they worked fine until i replaced them with the same exact ones...the factory ones give great performance, the only reason they woulden't would be that they are worn out, i'm not sure what you did to toast them at 70k but thats madness

edit, dumb post

the misfires and black smoke must be caused my severe crack addiction thank you for the help! i drove my truck thats how i roasted the plugs moron.

I would just upgrade to ACDelco Platinum Plugs and wires. I think they are good for atleast 100k maybe more.

thanks for the suggestion i appreciate it

aren't we a bit touchy, if its missing and blowing smoke at 70k theres other problems fouling the plugs..i second the ac delco platinums or iridiums both are excelent, just remeber ac delco was making plugs long before other companys were even cutting their teeth

Switch brands...... If you want. I have changed my fair share of spark plugs..... Plugs in LS-1's should be ACDelco 41-110 or NGK TR55IX (as some of you have probably found screwed in your truck to start with I did on my 2500).... Iridium's ONLY....

Ford plug shooters should get champion 7989's as it is a one piece plug and the OE's are a 2 piece another dumb IDEA guys at Ford came up with.

If your truck is dead stock.... and it killed a set of plugs at 70k..... Do you idle much? Tow? Burning any oil? Possibly had the intake and upper cylinders cleaned lately? My 2500 with a 6.0l had 178k miles before I changed the plugs.......... They were WORE OUT...... But I changed them a week after I started having a miss, as I was not going to do it before it started. Picked the mpg's up a couple by the way....

Plug wires..... AC Delco or NAPA Belden wires... Lifetime warranty....... Nuff said.... Take the Ohms law on them..... THEY AREN'T a foot long. Just don't melt a wire that is the only thing that is not covered...

Belden 700-399 is for Delphi coils. (round body coils)
Belden 700-989 is for Mitsubishi coils. (square body coils)

GM SPENDS A LOT OF TIME AND MONEY, depicting the best plug to use in their applications.... AC Delco no longer makes plugs they are boxing label for spark plugs at least on platinum and iridium... That is why you will find other part numbers on some GM plugs... i.e. the AC Delco plugs with NGK part numbers.....

sounds more like a fueling issue. well change your plugs/wires and see what happens..you might find that you have leaking injector(s)

BTW..i roasted the plugs moron statement won't get you much help so..

I have to agree with the last post name calling doesn't seem appropriate here. I have used taylor spiro pros and thundervolts and i now have a set of taylor 409 on my truck. i didn't have to put 409's on but i misordered them so now i got really big wires on my truck. at less than a foot any shielded plug wire will be fine. Delco platinums is an excellent choice, pricy bu, you get what you pay for.

Magnecor KV85's and E3's

Stock plugs (A/C Delco) and a set of Taylor wires and you're good to go.

don't learn the hard way like i did
'98 GMC 1500 350cid 123,000 miles on truck
i had a miss that would come and go i fought with it
fuel injector cleaner, the miss came back
cleaned map senser, the miss came back
replaced the plugs, the miss came back
money tight had hours cut at work so i avoided buying plug wires
finally replaced the wires, it ran great that night during trip to get pizza 5 miles round trip
next morning the truck ran real bad ( it made me sick driving to work that morning )
#7 cylinder header tube is cold when it is running
drove it that week for four days that way, Sat. morning started to pull head
the exhaust valve had gummed up during all this result the valve had stuck open and punched the piston, damage - bent valve, .060 deep cresant shaped dent in piston, bent both push rods on cyl#7
had the head rebuilt, replaced both lifters & push rods, gasket sets, sanded sharp edges off of the piston, I did all the work myself
thank goodness i know some people it all cost me about $300
all this in less than a five week time frame
lesson learned Pay now or Pay more later
bite the bullet and buy the Delco plugs and wires it will be worth it

on My previous post I didn't mention that those problems happened this past Jan./Feb.
two weeks ago check eng. light was on, Auto Zone scaned it for my it was -Bank one pre-cat O2 senser
bank one is the side i had all the problems, I didn't buy a new senser right then
got home removed and checked every fuse that related to ignition/ECM/emissions, they are all good
then removed O2 senser, did tests on it that i had read to do, and a couple of the tests failed
reinstalled it in the truck, to be able to drive it and runs good now the third time i started it check eng. light went off and the truck is still running Good
i guess there was a bad connection somewhere, there was some rust/corrosion on the senser threads, wire wheeled the threads
when diagnoising a problem Start with the Basics
