ok i did a search and find nothing about what brand/type of spark plugs to use for a 3.0L i want to change mine am i want to know what works best so i dont waste money on junk that doesnt last very long.

 

motorcraft, dont use anything else!! you can get them at the dealer or autozone, which is a little cheaper.

although you shouldnt have to change them this soon, how many miles do you have

 

2004 3.0

Autozone

Plug
AUTOLITE_DOUBLE_PLAT AUTOLITE_PLATINUM CHAMPION_DOUBLE_PLAT DENSO IRIDIUM AUTOLITE_RESISTOR CHAMPION_DOUBLE_PLAT DENSO PREMIUM
I recomend Autolite Double Platinum. You can also buy them from the dealer for a comperable price, maybe even cheaper.

You can thank me later

 

Yea, no need to change your plugs out already. I changed mine at 38K, but don't remember what I went with, lol.

 

i guess autozone switched over to autolite, i would get those, you may also be able to find them at wally world for a good price.

 

thanks for all the info i think i go with the motorcraft and according to the dealer they said it was time to change the fuel filter and spark plugs and a bunch of other things but i didnt have enough cash on me to have it done and i ask if i i could just do it my self at a later time and they said that could do the fuel fiter and spark plugs my self but i would have to take it in to have the other stuff done in order to keep the lifetime powerterain warranty and i have 31000 and according to the service book that they gave me it says to change them at 30000 miles.

 

thats crazy when i had some things done i paid the 50 bucks(Deductible) and that was once at 40,000 miles and that was my trucks first time back to the dealer since i bought the truck had some drivetrain stuff worked on they never questoined me about anything hell all the mechanic said to me was "hey that's a nice trickflow diff. cover i see you like to play in the mud too" i said hell yeah no mud puddle exscapes me and he laughed

 

hmm, if you have a lifetime powertrain warranty through your dealer, you may want to go through them and KEEP the reciepts. that way you cant get burned down the road.

 

Maybe it's time I did it. I have 48k on my 3.0 now.

 

yeah i keep every reciept just incase they were to ever give me any s***

 

Go with Motorcraft. And even at 31,000 miles you don't need to change them. I would wait until 40,000.

 

I threw in some motorcraft double platinums at around ~20,000. Got them for free, they were used out of another 3.0 for about a week.

 

i kinda figure that they were trying to sell me something that i didnt need yet. but when i do decide to change them i will stick with motorcraft

i was thinking same thing

 

whao.. an 04 with 30K!
