Drive Enhancers

The inventive products for trucks and SUVs are one of the best aspects of the automotive business. New or old, gas or diesel, there's always something different out there that makes driving more enjoyable. We did a survey of manufacturers who specialize in bolt-on performance products. As you can imagine, these items are popular--especially the ones made for diesels. What we found ranges from supercharger kits to brakes--and a few things in between.

AIRAID's intake system ($299) for 2005 Ford Expeditions with the 5.4-liter V-8 is said to add 19 rear-wheel horsepower and 28 pound-feet of torque. AIRAID; 800/498-6951.www.airaid.com

V-8 Supercharger
Whipple Superchargers' intercooled supercharger kit for 2004-2005 5.4-liter engines produces nearly 60 percent more power (475 horsepower/550 pound-feet) across much of the rpm range.

Turbo Kit
The S300 Air Werks turbo ($1245) is designed by BD Diesel Performance for 12-valve 1994-2004 Cummins 5.9-liter engines. The turbo provides low engine rpm spool-up, resulting in a 75-150-pound-foot increase in torque. It also reduces smoke emissions with 100-250 degrees F drop in exhaust temperature at peak load levels. BD Diesel Performance; 800/887-5030.www.dieselperformance.com
