I use Champion plugs on the Prowler --- OEM

If Prowler has aluminum heads is anti-seze compound used?
Read it was used between different metals so they wouldn't
grow together.

I was just looking at the book and it does not mention anti-seize but I don't think it would be a bad idea to use it.

I use anti seize compound when ever I change any car, truck & especially boat plugs. I had also heard years ago that metals do react when two different ones are in contact with each other, especially aluminum. Also it will protect the threads in the future when you decide to remove them. I also use it on other threaded items to insure they come apart in the future. Ford had major problems with their V 10s. The threads would come right out of the heads when you removed the spark plugs. Before I retired , I had an account with several of these engines, and tons of miles were put on these trucks. Using anti seize thru out the years on them, I never had a thread failure on these engines. Use it on any threads that come in contact with water or where you would like to protect them from outdoor elements, as it works very well and leaves a thin coat for protection. It is also a great idea to use it if you own a boat where you can get a lot of damage from electrolysis. Use it on any bolt or especially the propeller shaft and you will always have an easy time when the prop needs changing. The best use I have had with it is exhaust manifolds as bolts break off in the heads often on older engines. On a lot of engines, there is not a lot of space to get a drill down there to get the broken pieces out. It does eliminate a lot of nightmares.

I used a small amount of anti-seize in the middle of the threads.

For any of the NEW Kat owners, if the plugs haven't been replaced yet, change them out with: Bosch +4 platinum spark plug, no gaping required. You'll feel a little more pep.

I didn't have a long enough extension with me, so made it more difficult but still got it done

Have no clue what I used or if I put anti seize but hope I did ( think I did)

Think a 5/8 spark plug socket and 6" extension is needed plus the toris bit for coil pack

As others said, if you are unsure, pay someone, while at it change the water pump, timing belt & hoses.

The aluminum block 99 & newer are interference engines and breaking the belt can do major internal damage.

I changed mine out this past year with the Bosch +2, they seem to work just as great as the +4's.
