Spark Plug Upgrade

Are there any advantages of changing the spark plugs on a C63?

Is there a higher heat range plug available?

I know that the plugs that come on the C63 are NGK - ILZKAR7A10.

Anyone here changed there plugs?

Thanks for this info, I was wondering what type of plugs we had. Iridiums are the best out there, better be for $12- $14 a plug.

I bought 16 Bosch Platinum Ir Fusion plugs for another car...final cost after $2.00 rebate about $4.50 per plug, delivered. Amazing...

if anything youd want a colder plug, but that would only benifit a highly modified car where you were trying to keep pre detonation from happening. use the stockers

Whatever we're tuning!

For modifications adding up to 75-100 extra hp from stock, you should run a step colder plug. That will take up to 150 degrees out of your combustion chamber.

Denso Iridium are the BEST plugs out there! PERIOD!
