i am thinking about buying a Zex DRy nitrous kit off my friend for $300. My question is. i am only doin a 75 shot. Is it absolutely necessary to get colder plugs like tr6's? I just changed my plugs and got a tune up. The car is a M6 and has 75,000 miles on it.

 

depends on what kind of plugs you have. you CANNOT run platinums. I'd get some tr6's or autolite 104's. They are $1.50/each.

 

It is worth it to get colder plugs. I know its a pain to install them even with headers but its way better than a blown engine. THe Zex kit is awesome btw. I have quite a few wins under my Belt that would be losses if not for the laughin gas Oh and your gonna flip when you first kick it in.
