The aFe Stage 2 Si Cold Air Intake System with aFe’s maximum flow rate Pro 5 R filter is a simple yet powerful performance upgrade for 2009-2015 2.0L VW Jetta, Golf, Beetle and Passat TDI’s (through 2014 on the Golf) as well as the 2009-2013 Audi A3 TDI. It features a CAD designed intake tube for optimal airflow and a high-efficiency, low restriction air filter. No drilling or cutting is required – the 100% bolt-on system mounts directly to your lower airbox housing!
This performance Air Intake System out-flows the factory intake by a whopping 56%! That massive cool airflow increase translates to 23 lbs. x ft torque at 3050 RPM and 10 extra horsepower at 3150 RPM. If you’re planning to upgrade your TDI’s exhaust or add a power module, you’ll get the maximum benefit out of those upgrades when combined with this sealed intake system.
The improvement in air flow and air temperature of the Stage 2 Si intake will help your VW TDI breathe better and will lead to fuel economy gains in addition to increased horsepower and torque. Our testing of this cold air intake has shown gains of 1-2 mpg in improved mileage.
Your new TDI cold air intake system features aFe’s Pro 5 R filter media. The Pro 5 R filter is a washable and reusable oiled filter constructed with five layers of cotton gauze layered progressively more tightly for strong protection and superior flow rates. Filtration efficiency rates are in the high 98% range.
Engineered for maximum airflow and maximum performance, the Pro 5 R provides the highest airflow rates of all aFe filters. If you’re looking for maximum performance with maximum airflow, the Pro 5 R is the filter for you. This intake is a great choice for street racing and higher horsepower TDI applications.
