(Yes i was gonna bite the bullet and change the dreaded OEM spark plugs that everyone is scared off) My uncle works at a ford dealership so we made a deal that if we broke some of my sparkplugs or his we would help eachother out to get the broke plugs out since he has all the tools. Well long story short my coil pack boots where brown and his where black which meant mine where a different since and WAY SMALLER than the older OEM. I went on and called E3 and they said they where sorry but they have still not made a replacement for a motor that has been out going on 3 yrs.

Okay i need help guys i'm wanting to change out the OEM's for a performance spark plug. I've been looking at the Bosch Platinum +4 or the Bosch Platinum Ir Fusion, but i can't really find a difference. I'm thinking the +4 is the best one out there, but i can't find any info or ACTUALLY models #'s for my engine which is with the new remade heads w/ smaller spark plugs. (at least there a one piece..haha)

Do you guys know the model # or better spark plugs with actually data backing it up.

Thanks in advance for your info

Your truck is not meant to have those so called "performance" plugs.
Your Uncle works there did he not tell you this?

I actually have seen damage from those other plugs. They might burn hotter but that will make them seize up faster.
The technology is in your truck already, plugs are a waste.

The Motorcraft ones are the perfect ones for you.

If you want performance try gears-programmer-intake-exhaust etc...

PS.
People on here aren't normally rude unless they know you didn't look in the older posts for answers, or you just don't take the advice.

What does your uncle who works at the dealership say to use?

What makes you think using a non-OEM spark plus will burn the fuel any better than a new OEM plug?

Do you run 93 octane with the OEM tune because the 93 is "better" than 87?

I honestly used to look up to this forum for the latest and best aftermarket parts and insite on F-150's.

@ Cbmotorsports i couldn't agree with you more sir alot of "Opinions" must be taking care of this forum

You also said your Uncle worked for Ford, what did he say?
I have a friend who is a little older but retired from Ford 2 years ago and he says that OEM is the way to go on these plugs.

Does the cost outweigh the benifit?
How Long will it take you to recoop the extra $$ you spend on these plugs?

I don't care about truth i'm a very blunt person, but back with real life experiences or data sheets and not just straight beligerent bashing.

As far as the 5.4 triton engine the issue is with the two piece motorcraft plug ford used. they have the potential of breaking in half. also the 2004-2008 head design wasnt the best where the two rear spark plugs had very little thread depth for the plug. there is a kit you can get to lenghten it and avoid the blowing out and stripping and breaking of the plug. But all in all the best way to go for the 5.4 is to find a one piece design plug that is oem replacement as to avoind the feared breaking plugs.
