Spark Plug screw up

[rocky61201]

Just ordered new plugs on Amazon for my 06GT and got motorcraft SP515's instead of SP514's in the mail because I wasn't paying close enough attention during checkout.

I was looking foward to getting this done because I'm long overdue on changing the plugs. All I could find was SP515's are for the 5.4 3valve on the F150 and the gap is .045 instead of .054.

Are the motorcraft SP515's safe to use or should I mail them back and wait another week for the motorcraft SP514's to come in???

FYI - only mods are JLT intake and tune.

How much you want for them ? I need to do them in my 08 f150


Edit , I think those are for the old style heads .

sell em or return em , get the right plug for your application

Thanks for talking me out of a bad decision. I got amazon prime so the easiest/cheapest thing to do is return them.
