With the e85 market and flex fuel vehicles growing every day, Stacey dives into the myths and truths that surround ethanol and whether or not it’s a good choice for your vehicle. With a little help from Advanced Fuel Dynamics, Stacey installs a new fuel delivery system on a 2017 Mustang to show just how easy it is to up your performance and keep your engine safe at the same time. After that, Stacey and the crew head out west to tell the story of Bestop and how they’ve been making removable Jeep tops for decades. From rock-crawlers to the mall crawlers, Bestops unique past allows us to see what the future of the Jeep world will be. Finally, if you’re trying to decide between a stick or automatic transmission… hang out for a while as Stacey talks about converting your boring automatic to a lively manual transmission. We’ve got all this and more on GearZ!
