    I recently had my first service done and had the stage 1 done at the same time. I am wondering if I should put the split fire SE plugs and 10mm Fat Wires on it now just for the improved spark.

    Early on when Splitfire plugs came out I heard they also had problems with pieces of the "forked" electrode breaking off...any truth to that? :25:

    Don't waste your money. The theory on Splitfire plugs is good, and it looks good too.... A wider (or split) spark will offer a more complete burn. But no matter what happens, only one spark will throw at a time. One fork or the other, but not both at the same time. They have been around for years, and many independent tests have found no improvement over stock.
