I reached out to Aaron @5startuning and he said it was not required, but directed me to some plugs and advised it would only help, not hurt. I will probably scoop them up in near future.I would go with whatever your tuner recommends. On my Focus ST, Stratified strongly recommended I go with colder plugs, the downside with that was that I had to change them about once a year.
