I don't know about the Brisk, but the Motorcrafts are made of platinum and you should not use anti-sieze on the threads. Since the Brisk are short life, they probably are not platinum.

I'm curious though, with the original plugs having so much carbon, what gas do you run? Is it a gas with a good detergent?

 

I run 87 octane. Mobile or bp. I just purchased the truck so I'm not sure what the previous owner ran. I have not put any chemicals or cleaners through it. It doesn't seem to burn any oil.

The brisk plugs are silvers. Could you explain the drawback of putting antiseze on the threads? I've put 100mi on these new pulgs and no issues as of yet.

 

my 04 has just under 70k on it. it is coming time soon to change the plugs on this 4.6L and im nervous about it. i know most of what ive read with breaking plugs is on the 5.4L 3V.. mine is not a 3V i dont think. so maybe it wont be so bad. even still i may just have the dealer do it.

 

If you put antisieze on those that do not require it, such as p;atinum, ther are two drawbacks. They may not torque down properly and might back out gradually.

 

A small dab on threads sure makes it easier when removing plugs. The grease does change the torque factor since its a lubricant its going to reduce the friction so if you torque something to its required torque there's always the possibility of over-tightening the bolt or plug when using anti-seize. But sparkplugs are not tightened all that much, maybe 15-30lbs/ft, so its doubtful that you will stretch,distort, or tear out the threads.

I have used anti-seize all all of my vehicles and have never had a problem with threads or plugs coming loose. I sold my last F150, an '01, with 205k miles. I think I changed the plugs at least four times without any issues.

 

Cool thanks for the info!

 

Double post!

 

I'll second that. I used Autolite plugs and I put some on my threads and shield.

 

Congratulations on the plug success. I am also concerned with the plugs you put in, but hopefully you won't have any problems!

 

Actually the plug itself should have nickel in the metal its made out of so they do not need anti seize on the threads at all. I would only put it on the shank as described on the Ford TSB.

 

Why are so many people down on the Brisk plugs? They have been around for quite a while and stand up to some extreme usages. Have you had a bad experience with them, or speaking only from what you have read here?

 

I'd be more concerned with the plugs you put in your truck rather than the OP's Brisk racing plugs. I've heard far too many stories here of people having troubles with the autolites.

 

Actually I've not heard of a failure of autolite in 3v engines they seem to be working ok in those. The 2v engines they were a problem in.

 

You're right.

With the past history the 2v engines have with the autolites I'd still steer clear, but that's just me. :o

 

X2! I am going to replace with MotorCrafts when it comes time!......
