With Shelby American’s EcoBoost kit, only four are truly functional; of those four, three bits come straight from the Ford functionality catalog. You know, the catalog available to everyone, not just Shelby. There is the $299 Ford functionality short-shift kit, the $1499 Track Handling package.
It is of little surprise that the aftermarket is responding in kind and whipping together hop-up parts for the turbocharged four-cylinder pony car. Throwing money at functionality mods months or even years after leaving the dealership with your new ride makes sense; buy the Mustang you want or can afford.
The Shelby GT EcoBoost package’s price has us scratching our heads, since it is $23,995 on top of the price of an EcoBoost Mustang, for a total minimum cost of $50,195.
We will spare you the list of 335-hpish vehicles that can be had for less and skip right to the $33,200, 435-hp, V-8–powered factory Mustang GT. Or, you know, the $49,995 Mustang Shelby GT350, which has an amazing-sounding flat-plane crankshaft V-8 pushing 526 horsepower.
Add it all up, and it is about $3787 worth of parts. So where is the other $20,208 of your money going? Well, there are some carbon-fiber bits, Shelby GT stripes and badges, plaques for the dashboard and engine cover, Shelby floor mats, and 20-inch Weld Racing wheels with Michelin Pilot Sport tires.
The kicker Shelby American goes out of its way to declare that after the build, it ‘retains all take-off parts.’ Wave goodbye to any possible savings from selling the stock wheels and suspension components.
As for those who already own a Mustang EcoBoost, our instructions are to also visit a Ford dealer, and order those Ford functionality parts. We suggest that if you want a more powerful Mustang, visit your nearest Ford dealer and ask to test-drive a GT. Even better, ask for the GT with the optional functionality package.
