What mileage do you guys recommend for plugs?

 

around 40k. Depends on plugs though. DO NOT GET E3's.Bosch Platinum's are trash too. Buy Motorcrafts or NGK's. They should also come pre-gapped. I would recommend doing your wires too at the same time.

 

I would do them around 60k-70k. Thats when I did mine. They are pretty hard to change if you dont have a lift.

Thats why I say wait to 60-70k.

 

Lord of war has a point lol. I don't know how hard it is to change plugs on a 3.0 but on a 4.0 its easy on the drivers and hard on the passenger side. With headers its damn near impossible. Even with a lift....

 

They are rated for 100 but that seems too long. 60 is good.

 

^^ ditto what he said....i used the bosch platinums because the guy who sold me the truck left them in the console....when the weather got cold....(50's) i started getting misfire codes... threw in some Motorcrafts and it cleared up

i'd say the 60k mark would be fine to change them

 

What plugs and wires would be the best performance combo?

 

Motorcraft Platinum plugs or Iridium. NGK Platinum or Iridium.

would the plugs and wires go well with the screamin demon coil pack?

 

I changed mine at 40K and found half of them severly worn. HUGE gaps.

40-60k sounds like a good deal to me.

 

When I changed my OEM plugs at 85K they were done. The electrodes were very unevenly worn and the platinum was gone. My truck has used a lot of E85 though, which is hard on plugs.

I used Motorcraft plugs from the parts store. The ones I got were not pregapped for a Ranger. They were at around .054 out of the box, so I regapped them to .044.

 

Did mine at like 60ish-k

Autolite Double Plats and Underdog wires. Wasn't that hard, just a little time consuming to route the wires. You don't need a lift, I had one but didn't use it.

 

I did mine at 60k and the gap was terrible. I used the Underdog wires and Motorcraft Plats and it ran great. Prepare for some bruised knuckles though

 

I have the screamin Deamon coil pack. I think it was worth it. My plugs are gapped to .065 and I know I get consitant spark.

 

Thanks for the replies, yeah im prepped for bruising and all.

 

Anybody use the denso Iridium's yet?

 

Rich(wydopnthrt) has. He likes them over the NGK Iridium plugs. I was going to a set of the Densos but I'm selling so no need for them.

 

Oh alright thanks

 

I replace mine at 91k with autolite platinums. I still haven't got wires yet,
