my dad has a 95 ford f150 with the 4.9 5speed and tomorrow we plan on checking and possibly replacing the spark plugs and wires but i am not sure what would be the best brand to use or what the gap should be? also any tips for changing the plug? we have been talking about doing it for years but the job just looks like such a pain in the @$$. the truck is already broken enough without us braking even more so any tip would be greatly appreciated. thanks

 

anyone? would champion spark plugs work or i there other brands that the engine would be much happier running. should the gap be set to .044?

 

Motorcraft. The six is the easiest engine to change plugs on.

 

What Sean said, 15 min job at most, and you're right 0.044" gap. I use Champion copper plus an it runs beautifully, better than my iridium NGK ones that it had when i got it.

 

ended up finally changing the plus and wires and they were long past needing to be replaced but i think the big problem was solved after we found the gas leaking out of the fuel filter that was almost completely hidden behind the gas tank. to get the one plug out we had to run the engine for about 5 minute. good thing the thing don't have aluminum heads or i would be in trouble.

 

Jeeeez sure let em go didn't you? Gap on those almost doubled from stock.

 

Anything but platinum. Copper is best.

 

Ah man you had lawnmower plugs in it! Lol Yeah I’d say you got the best out of those. And always use anti-seize when you put in new ones along with boot grease saves time and aggravation next time.

Motorcraft coppers runs best in most of these trucks.

 

I use champion copper plus plugs, work great for me with NGK 8mm plug wires

 

there is less than 300,000km's on the engine and those are not the stock plugs so who knows exactly how many km's there were on them. my dad has never done much maintenance on his vehicles. just fixed the stuff that breaks. we just used what the parts store had which was champion plugs and wires. i was actually a bit surprised that the champion wires were 8mm. the ford dealership would have had to order plugs in so just stuck champions back in. the thing passed emission testing with flying colors last time it had to be done so it couldn't be too bad of a plug. i also made sure to use to use anti seize on the new plugs. i hopefully never have to take them out again but they should not be as hard next time.
