My opinion for what it's worth, is that exotic spark plugs are a waste of money unless it's what was oe for the car or you have a modified engine and ignition system that requires their use...or you're trying to address a specific problem and even the the best solution is to diagnose and remedy that problem.
For a stock engine all one needs is a spark plug equivalent to what the factory installed...right reach, gap and heat range. Brand is a subjective thing, so whatever you like.
Spark plugs and items like coils are greatly hyped and buying them usually accomplishes little more than lightening your wallet and increasing the bottom line of the exotic spark plug maker and their ad agency.
