DynoTune's fully automated nitrous bottle warmers are built to perform. This bottle warmer is one of the best available and uses the smallest most accurate pressure switch available. Unlike the competition, DynoTune's is fully adjustable! Competitor's bottle warmers hold the pressure within 300 PSI, but DynoTune's holds it to 50 PSI. It comes with all the components to install and is made out of superior components! It will work with your existing bottle adaptor. It will keep your bottle at an optimum pressure 900-950 PSI (adjustable from 550-1250 PSI). The heater is a full silicone flexible heater with velcro straps for quick bottle changes. Team this up with the digital nitrous pressure gauge you have the most sophisticated nitrous pressure control system available.
