Avoid gimmicks. Splitfire, Thisfire, Thatfire, it's all junk.
Just get good quality plugs that are rated for your engine, gap them properly, and spend your mental energy on other things. You'll have far more effect on your mileage by how you use the skinny pedal than any gimmick spark plug has ever even claimed.

The SP546 is for a 3 valve.
