Enhance your Audi A4's performance with the K&N Engineering 69-9505T cold air intake system, designed specifically for 2009 to 2013 models. This system features a mandrel-bent aluminum intake tube that ensures smooth airflow, resulting in a guaranteed increase in horsepower and torque. Its premium washable, reusable high-flow air filter with oiled cotton media allows for up to 100,000 miles of service under normal highway conditions, reducing maintenance costs and improving engine efficiency.
The oversized, conical filter design maximizes airflow intake while the included custom heat shield or air box helps protect against engine bay heat, maintaining optimal intake air temperature for better combustion. The entire installation can typically be completed in less than 90 minutes, making it a convenient upgrade for enthusiasts seeking immediate performance gains. Designed to meet EPA standards, this system is compliant with environmental regulations, though some versions may not be legal for sale or use in California on pollution-controlled vehicles, so check the CARB status for your specific model.
Built by K&N Engineering, a trusted name in performance air intake systems, this product is backed by the No-Hassle Lifetime Limited Warranty, ensuring durability and customer satisfaction. Whether you're looking for improved throttle response or increased horsepower, this cold air intake system offers a reliable and efficient upgrade to your Audi A4's existing intake setup.
