104+ Octane Boost

The 104+ brand was America’s first octane boost. And since 1975, it remains to be the best octane boost out there, hands down. Why are 104+® octane booster products the best? Because 104+ was made for powerful, muscle-bound, high-performance engines that need to scream at the top of their lungs, so to speak.

104+ octane boosters are not for those red-blooded American muscle and collector car owners who kid around. It’s made for those who demand the maximum performance out of their engines, like you. And for you, only 104+ will do.
