I have misfire on cylinder two, pretty sure it's spark plugs so I wanna replace with good ones. What do y'all use? I see they have ones with three points for the spark to hit? Wouldn't the electricity just go to the spot with Least resistance? Or just stick with oem? Thanks

 

Oem nickel coated. Are trucks are VERY picky about spark plugs or they'll spit em out, literally lol

 

Ngk iridiums. that's what I'm going with next with efx coils.

 

What about those E3 spark plugs that are always on the powerblock on spike tv? Has any one used those or heard anything about them?

 

The tritons do not like E3 plugs. The are shrouded and actually inhibit correct burn patterns. I myself have been using NGK Iridium IX and EFX coils for the last 80k miles. I still replace my plugs once a year regardless of mileage. But I still would not push plugs past 50k if you run fuel with a Ethanol blend.

 

+1 ^. The 4.6 almost as a rule, needs Nickel plugs - and there are multiple threads here about that, due to heat characteristics. My stepson had a 2000 Crown Victoria, with a 4.6, that he went with so-called double platinum plugs, and 20K after the change, one was literally spit out of the head, and required the "sert" job (`$250) to fix.

 

Set of NGK Ird. and two coils, average cost would be???

 

So the Ngk are nickel coated and will work? I dont mind if there a little more costly. Theyve only been changed once and it has 170k on it.

 

Any where from 15-22 bucks a plug as for coils i know all 8 efx cops are around 500 dollars i believe its been a while since I've been on their site.

 

Holy chit
