Hey !...one guy said I indexed my plugs and noticed a big improvement. Well, this depends alot on other factors to achieve this. Normally when indexing your plugs you will only notice a Slight improvement at the drag strip during high rpm range. Go ahead and do it if you want, but don't expect to see a regular seat-o-the-pants experience !

 

Here's some visual aide to go with the explanation:

 

Nicely done! Thanks

 

anyone run iridium plugs?

Good info drukanfu and tucci. Thanks.

 

What washers do you use to index the plugs with if i may ask?

 

Great info!

So the black mark on this plug is actually that BACK side of the metal curved part on the plug? So the spark is being MORE thrown towards the engine and not outward by your leg?

THANKS!

 

I got them here:

I use Blue Lightning plugs that have a 2 year warranty and seem to give a little boost.

I'm happy running the iridium plugs.
You might want to go one range colder though, for any plugs on the 103 that is.
