X-1 Carbon Fiber Air Intake

The X-1 Intake was developed to deliver the cool, dense, fresh air this tuning requires. Since any turbocharger works on a pressure ratio, the more cool dense air at the compressor's inlet the faster it can achieve requested boost for less lag. The less work the turbo has to do maintain this pressure the less it will HEAT the intake charge. An intake's efficiency can be measured by the amount of pressure drop ahead of the turbos at wide open throttle. The X-1 Intake system measured HALF the pressure drop of an RS4 airbox (-1psi vs -2+psi).

Many already realize the benefit of a large, open element filter. Unfortunately with unshielded designs that benefit is somewhat compromised, especially at lower speeds as the engine may be getting less pressure drop through a big filter, but it's aspirating hot air that's already gone past the intercoolers, radiator, and exhaust manifolds. The X-1 Intake's unique heatshield gathers fresh air from the stock snorkel feed, around the headlight, and in front of the radiator and intercooler; all high-pressure sources of fresh unheated air. The weatherstrip on the top seam of the airbox seals to the underside of the hood when it's closed.

Previously an ITG filter was used with our design, but it was found that the newly available AEM Dryflow filters provide both superior flow and lessened contamination of the mass airflow element.

Fitment and Installation:The air filter and piping can be sized to fit the stock S4 MAF housing, RS4 MAF, or ANY aftermarket MAF housing. The install job takes some basic tools and the courage to drill two holes in your firewall to mount the Ignition Control Module heatsink. All included hardware is either aluminum or stainless steel, all made in the USA.

AWE Tuning Sport Pedal Covers

The shortcomings of all the pedal sets out there really frustrated us, so we decided to design a set with a clean sheet of paper. Inspired by some of the high dollar pedal kits available from Europe, we melded all our favorite pedal cover features, situated the bolt hole placement to provide proper and easy installation, and offered them at a price that can't be beat.

Key features that set our Sport Pedal Covers apart from the rest:

  • Pre-installed rubber nubs for grip with wet shoes
  • Hard anodized finish for long appearance life
  • Stainless steel hardware, included installation wrench
  • Radiused corners on clutch and brake pedals for shoe clearance
  • Accelerator pedal "bump out" for easier heel and toe driving

APR Boost Gauge

**INSTALLED**

The APR Boost Gauge utilizes a VDO boost gauge contained in a vent-replacement pod. The pod was designed on the computer with Pro-E for the best in fit and finish and is injection molded in plastic, giving you factory-like look and feel. The gauge itself is a 52mm mechanical VDO gauge giving very accurate and reliable boost and vacuum readings. It reads from 30 in. Hg of vacuum to 25psi of boost. For higher boost systems, a 0-30psi gauge without vacuum reading is available.

Rear 21mm H&R Swaybar

H&R swaybars are another solution to further controlling bodyroll over springs and coilovers. They can also be used with the factory original suspension, offering greater roll control with little sacrifice in ride comfort. All H&R swaybars use a teflon mesh lined bushing to eliminate squeaking under movement and the need for periodic lubrication. Trust us when we say that this is a terrific idea!
