Ive got a needswings intake and a code 3 on the way... THis seems to be a common combo. Maybe others will see this thread in the future and have their questions answered.

1. Are colder spark plugs necessary?

2. Are smaller gapped spark plugs necessary?

3. Is better cooling neccessary?

I know all of these things are a good idea but I'm curious how much of a disadvantage if you don't do them. Anything else?
