NGK Laser Iridium Spark Plug 94201 heat range 8.
Pros and cons?
I was told the computer has a problem with the resistance of this plug.

I am looking for the Spark Plug with below features: -

>>Original equipment manufacturer approved
>>Precision laser welded platinum center electrode
>>Dual platinum contacts reduces gap erosion

I've used both. Haven't really noticed that much of a difference. My engine seems to be marginally smoother with the platinum plugs. The NGK Iridium plugs seem more readily available at a decent price. The platinum ones are more expensive. Iridium supposedly lasts longer than platinum.
