Radix Retro Supercharger: 2003-2009 Avalanche, Yukon XL, Silverado, Sierra, and Suburban
Radix Retro may sound like a DJ's name, but it's an MP 1900 TVS supercharger system for 2003-2009 4.8-, 5.3-, and 6.0-liter 1500 and 2500 Avalanche, Yukon XL, Silverado, Sierra, and Suburban. It replaces the MP 112, and part of the redo meant moving more air and making more power over that model. Parts include an equal runner length intake manifold with integral water-to-air intercooler, the MP 1900 TVS supercharger itself, high-flow fuel injectors, and everything else needed for installation. It starts at $5950.
MBRP Black Series Performance Exhaust: Most Diesel Pickups
The Black Series performance exhaust from MBRP features a high-tech coating that the crew developed specifically for the exhaust system, making it resistant to chips and discoloration. The Black Series will fit most turbo-back, cat-back, and filter-back diesel pickups in single and CoolDuals configurations. Pricing starts around $377.
Rugged Ridge Cold-air Intake System: 1991-2006 Jeep Wranglers
The Rugged Ridge cold-air intake system for 1991-2006 Jeep Wranglers features a polished-aluminum, mandrel-bent intake tube, which replaces the factory airbox, improving fuel economy. A black-powdercoated heatshield separates the filter from engine heat and debris, while cold air makes its way through a high-flow conical air filter. The dry-panel design of the filter won't require oiling. Depending on how your Jeep is set up, you can expect an additional 10 horses and 12 pound-feet of torque. Each 1997-2006 kit includes a billet-aluminum throttle body spacer. It's around $200.
