spark plug issues on S197
I see a bunch of information online stating that the S197 spark plugs get stuck in the heads due to carbon build up and no antisieze on the plugs. Have you all removedyour plugs and applied antisieze on them to prevent future problems?
There is a special service procedure instructing how to remove them properly to try and prevent the breakage of the plug in the heads. They even have a special tool to remove the broken plugs so you know this has got to be a big issue.
I am guessing I should probably do mine since I have about 14k on the clock.
What are peoples thoughts on the champion plugs? I think they can't break off in the head like the factory ones.

I gather you are refering to the Champion 7989 plugs? They would be a great replacement for any car that runs the stock plugs and stock heat range. They aren't recommended for the supercharged cars that may require a colder heat range plug.[sm=smiley20.gif]

For supercharged cars the ford autolites are good.

RE: spark plug issues on S197
great info.
I may have to go with the Champion 7989 plugs. I am thinking about going to the 3.6" Saleen pulley for higher boost and I think that pulley size is about the limit for the stock heat range plugs??
I know JDM has some autolites that are one heat range colder and they can pre-gap them.

Man guys, thanks for this info This is the first I have heard of this....I will be pulling mine out and replacing them with the Champs next winter! With only 4k on the clock I'm hoping I won't have any breakage issues to worry about []

The only two plugs that I know of that have the new solid/one piece design that eliminates the breaking issue are the Champion 7989 plugs for normally aspirated cars and the Brisk 3VR14S for 450+- HP supercharged cars. I'm sure there will be others coming to market in the future.
Brisk one piece plug design: Notice from the threads all the way to the electroide is all one piece. The Autolites and other factory plugs are crimped where that beveled area is and thats where its breakling when you try to remove it.

If anyone changes to the 1 piece Champions make sure you pull them every year and clean them up & re anti-seize them! If you leave them in to long with alot of carbon buildup below the threads you will just tear out your threads if you force them out!!!
