Spark-plugs And Coolant

[therzl]

I own a '96 Cobra with 110k miles. The engine is stock and non-aspirated. It needs new plugs. Is there any particular type/brand that will provide me the best performance (e.g., platinum)? Also, the radiator is a Fluidyne and the coolant needs replacement. Is there a preferable type/brand and should I add a corrosion/rust inhibitor (also type/brand?)? Thank you very much.

The best spark plugs for performance would be copper spark plugs but, they don't last as long. The best spark plugs for longevity would be platinum spark plugs. I highly recommend using Motorcraft spark plugs on our cars. Factory torque spec is 12-15 ft. lbs using a torque wrench. That is barely more than hand tight. I would just use antifreeze and no additives. I always use Peak or Motorcraft antifreeze in my Fluidyne radiator.

If you flush and refill your cooling system on time you should not have to worry about unwanted rust/corrosion in your cooling system. I have always used 50/50 antifreeze.
