The aFe Stage 2 Si Cold Air Intake System for the 2009-2012 VW Jetta and Golf TDI’s 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 Jetta’s exhaust or add a power module, you’ll get the maximum benefit out of those upgrades when combined with this sealed intake system.

A STAGE 2 Si Cold Air Intake System comes with a sealed airbox for a clean factory look and less intake noise than traditional open systems. To see a Dyno Sheet and a picture of this product installed, click here.

The improvement in air flow and air temperature of the Stage 2 Si intake will help your VW Jetta TDI breathe better and will lead to fuel economy gains in addition to increased horsepower and torque. The sound difference is also noticeable and makes for a nice improvement in engine noise.
