True Volkswagen TDI enthusiasts have something to cheer about as new Performance and Upgrade product releases are here for the 2009 VW JETTA 2.0L TDI Sedan and Wagon. After Volkswagen's decision not to manufacture 2007 and 2008 VW TDI'S, many TDI enthusiasts have pounced on the chance to buy a factory fresh 2009 TDI Jetta. With no TDI vehicles coming off the VW assembly line for a few years, manufacturers of VW TDI upgrades had to turn their attention to other product lines. Now, however, with the popularity of Volkswagen's new 2009 TDI Jetta's, upgrade and modification companies have taken note and are again giving car owners the types of Performance products they crave - products that until only recently had been reserved for older model VW TDI'S.
Performance Cold Air Intake Systems and Rapid Power Module's, or "Chips" as they are often called, are two of the easiest, least expensive, and most effective upgrades you can make to your 2009 TDI Jetta. Diesel engines want cold air to breathe and properly atomized fuel to burn, and an upgraded intake and module will give your TDI just what it needs. If you are interested in maximizing the full potential of your VW TDI, read on.
To give your Turbo Diesel more cold air, a high-quality choice comes from Advanced Flow Engineering, or AFE Power as they are commonly known. AFE has recently released a Performance Air Intake System for the 2009 Jetta TDI 2.0L with an impressive list of benefits and performance data. The system is 100% bolt-on, mounts to the lower airbox housing, and no drilling or cutting is required. After a simple 15-30 minute installation, you can expect air flow to increase 56% over stock. Horsepower gains average +10 at 3150 RPM, and expect Torque to increase by 23 lbs. at 3050 RPM. The system comes with a high efficiency, low restriction air filter in your choice of either a Pro Dry S or a Pro 5R. Most people choose the Pro Dry S for ease of use with filter cleaning being a simple wash and air dry.
Performance modules improve TDI fuel economy and provide extra horsepower at the same time by improving the efficiency of the vehicle fuel injection system. Performance market manufacturer and TDI stalwart Bully Dog now markets a "Rapid Power Performance Module" for the 2009 VW TDI Jetta which effectively improves fuel economy and horsepower. This module is a simple inline, between wiring harness, plug-in chip designed for safe and long lasting use. It is adjustable on-the-fly, allowing you to choose between three power levels; Stock, +10% and +15% horsepower via a simple toggle switch that can be left in the engine bay or installed within the interior of the vehicle for easy access. The total horsepower increase from this module on the highest setting according to Bully Dog's Dyno testing is +25HP and a torque increase of 30 ft-lbs. If you can keep your foot of the gas pedal you should even see some impressive fuel economy gains on a car that already gets remarkable mileage.
