The Nitro Power product is an additive, for additional power and torque. It's a 50/50 blend of nitro propane and Koolinal. Handle with care! See product spec sheet to confirm if this is for you.
The Higher Octane Booster product is a versatile fuel additive. Not only does it genuinely increase octane by ten numbers, it is also a highly effective fuel stabiliser and fuel system cleaner. At Birch Performance we keep a bottle of this handy in our car, just in case! See product spec sheet.
