Indexing spark plugs?

[midnightbluS10]

Anyone here tried it on their syty? Curious to see if there were any noticeable changes? Plugs lasted longer or shorter...anything.


Thanks.

Yes, it doesn't do anything for the life of the plug. It just ensures it's in the optimal position. Alot of headache for somthing that's forced induction.

Alot of work for little or no benefit.

Spend your time and $ on something else...
