Upgrading Spark Plugs

[Brichinelo]

Will upgrading spark plugs help out with vehicle performance? I know it’s not necessary but will it enhance the vehicle any ? Will driving dynamics enhance or are the spark plugs more of a protection stability thing. Thanks in advance.

You won't be able to tell the difference, unless you tune or get a piggyback. It won't hurt anything though, and if you plan on tuning, you'll be ready. Gap appropriately. Burger Tuning, for instance, recommends a .022 gap.

Not needed if you aren't going to tune of any kind.
