ok my truck used to be a old farm truck and they never even changed teh oil, I have it running so smooth its like new, good compression on all 10 cylinders its a 2500 1996 gas 8L, can anybody tell me the oem spark plug number I need for it? the wires are on the way from rock auto but I cant read the numbers on the plugs anymore

 

Should be printed on a label under the hood somewhere as well, usually on the radiator support. If that isn't there, local parts store should be able to look 'em up for ya, and have 'em on the shelf. Standard copper plugs only please. These guys don't seem to like the rare-earth fellers.

 

5224 Autolites(copper).

 

thanks guys, It doesn't say under the hood but I DO have the original owners manual which tells me nothing LOL except refer to my emissions label, here's a pic of it in case I'm missing anything

 

NGK 4291 spark plugs have served me well.

 

I looked them up since the emissio0n label doesn't have them , I ordered Champion QC9MC4 plugs, they came yesterday along with Federal 3230 V10 wires I prefer all stock since the ones in my truck were put there by the factory in 1996 and my truck will STILL pull two full peanut trailers and not even know they are back there

 

I had no luck Champions, Would run OK for about a year then misfires. Switched to Autolites and have been happy with them.

 

I've been running the Autolite double platinum spark plugs for years in my truck. No issues whatsoever.

 

I have never had any luck with autolite spark plugs before, on Chevys I always used AC Deloc, on Fords, I used Moorcroft, and on Chryslers I have always used Champion, or course I have also never owned a vehicle mads after the tear 20000 either
I have had minimal luck with Autolite on a Chevy before but they lasted a year
