I have a question for everyone out there in F150 land,

Has anyone used the ford Racing Zero degree spark plugs on their truck ??
they are a Bit Expensive, $141 set of 8, @ summit Racing.

If so how do they work, any problems, Etc, etc.

Thanks for your help

I have not used them I just do the oem replacement plugs when I change them. However I am subscribing to this to see if someone has I may go to them if they have good reviews.

 

I bet they work great.
Have some hesitation though.
Looked them up at summit and didn't like what I saw in the description.
It said "copper tip"
OEM tips are "platinum"
So if someone uses these you might be in the same boat as a "brisk" plug. Changing them out every 15K-20K.
