Review on Dorman 800 155 Double Bead Fuel by Matt Mosley

Automotive enthusiasts beware! When I TRIED this supposed performance fuel system solution, I was sorely disappointed. Despite the claims of increased fuel efficiency and horsepower gains i noticed no real improvements in my vehicle's performance .The only benefit I can give it is that it was easy enough to install. On the downside, it was a complete waste of money and did nothing to enhance my driving experience..
