5.0 spark plugs
I went looking for new plugs for my '97 5.0, they are MotorCraft# AWSF 32E that are hard to find, they crossed over to NGK #TR55IX platinum so I bought them. When I compared the two the MotorCraft has a shorter thread section, then I saw they have a tapered seat and the seat was in the same relative place. I search here and other forums to find that Ford has abandoned the original plug design and this longer threaded plug is the approved replacement.
I just wanted to pass this along. |
I believe I'm running the same plugs in my '00 Mounty and they're working pretty good, 10,000 miles later.

I was unable to replace mine, I had the wrong plug wires! The plug wires are special to that motor and they sent me a generic set for a 5.0, the proper ones have clips for the coil pack and at least 1 wire has a metal shield near the boot.
Hopefully I'll be able to get them replaced this week. When I ordered the parts I had no idea the plugs were so expensive, I was used to paying under $20 for a set of NGK and about choked when I saw the bill. I guess they are OEM or better caliber, no problem with that. I believe I'll replace the inner fender splash skirts while I'm at it, wirebrush the rusty stuff and repaint the inside. |

Correction, I'm not running NGK plugs, but Autolite XP104 plugs (also iridium) for $4 a piece on RockAuto. I also replaced my inner fender shields for about $6 per side. For plug wires, you have some options. Motorcraft set is available, so are Taylor wires, just depends on how much you want to spend... plan on $80-130.

Yup, the plug wires are salty, as I learned. Sometimes you spend lots of money but can't see it, when you see and feel these wires you know you paid a fair price. My truck has just under 100K miles & 20 years on it, the original stuff lasted this long, best I replace 'in kind' and they might outlast me.

I dunno what all the hub bub is about with the spark plug for a 5.0. I just use the basic champion copper core cheap plugs. They work fine and since I have a hole that burns oil and deposits it on the tip I change at least that one a couple times a year. No special plug needed. You're over thinking this.
I did invest in some monster wires for my plug wires. They weren't cheap and I had to buy boots to protect the plug ends from the manifold heat. |

I understand all that and I've tried them all. No difference. 237k miles and still runs great. I'd drive it anywhere. Wore out? Nah, just broke in.
