aFe Pro Dry S Cold Air Intake for Mk4 TDI (ALH, BEW)

What It Is
An aFe Pro Dry S cold air intake system for the Mk4 ALH and BEW TDI engines. It replaces the restrictive factory airbox and intake tube with a one-piece, 16-gauge powder-coated heat shield and a washable, reusable conical filter.

Why It Helps
Freeing up airflow into the engine is the whole point here. aFe rates the gain at up to 8 extra horsepower and 11 lb-ft of torque over the stock intake, which on a diesel is the number that actually matters day to day, since torque is what you feel pulling away from a stop or passing on the highway.

What's Included

• One-piece, 16-gauge powder-coated heat shield, built to need little or no assembly
• A washable, reusable conical air filter made from 100% polyurethane, rated for long life and multiple cleaning cycles rather than one-time disposal
