Cold Air Intake for Mercedes Benz C300 C350 (2008-2012) 3.0L 3.5L Engines - Black

Cold Air Intake System for Mercedes-Benz C-Class (2008–2012) - Dual Filter Design & Increased Output & Airflow

This dual-filter cold air intake system is designed to replace the factory air box on 2008–2012 Mercedes-Benz C300 and 2008–2011 C350 models equipped with 3.0L or 3.5L V6 engines. The system reduces intake restriction by using aluminum intake piping and dual high-flow air filters, allowing increased air volume to reach the engine. This results in improved throttle response, enhanced airflow efficiency, and measurable gains in horsepower and torque across the RPM range.

The intake uses T6063 aluminum construction with optimized piping diameter to create a less restrictive path for incoming air compared to the factory intake system. The dual-filter configuration provides increased filtration surface area while maintaining lower restriction. The design allows the engine to draw cooler, denser air for improved combustion efficiency.

Performance & Design

Airflow Optimization: The system is engineered to improve airflow efficiency by eliminating restrictive elements in the factory intake path. Testing under controlled conditions has shown potential gains of 7–10% in horsepower and 6–8% in torque. Actual performance improvements will vary based on vehicle condition, elevation, ambient temperature, and existing modifications.

Dual-Filter Configuration: The dual high-flow air filters provide increased filtration surface area compared to single-filter systems. This configuration reduces restriction while maintaining adequate filtration for engine protection. The filters work in parallel to maximize airflow capacity to the engine.

Construction & Materials

T6063 Aluminum Construction: The intake pipes are constructed from T6063 aluminum, which provides corrosion resistance and reduces weight compared to factory components. The aluminum construction maintains structural integrity across engine bay temperature ranges while resisting oxidation.

Filter Design: The high-flow air filters use washable filter media that can be cleaned and reused. The filters provide adequate filtration while maintaining lower restriction than factory paper elements. The dual-filter design increases total filtration area for improved airflow capacity.

Installation Note:
After installation, disconnect the negative battery terminal for approximately 30 seconds to allow the engine control unit to reset. This allows the ECU to recalibrate fuel delivery and ignition timing parameters to optimize performance with the modified airflow characteristics. Professional installation is recommended to ensure proper fitment and secure connections.

Filter Maintenance

Inspection Schedule: Inspect both air filters every 5,000 miles and clean if necessary. Driving conditions such as dusty environments, urban traffic, or performance driving may require more frequent inspection and cleaning.

Cleaning Procedure: Remove both filters from the intake system. Gently tap each filter to remove loose debris. Apply an appropriate air filter cleaning solution to both the inside and outside of each filter element, working it into the filter media. Allow the cleaner to soak for approximately 10 minutes. Rinse each filter thoroughly with low-pressure water from the clean side out, continuing until water runs clear. Shake off excess water and allow both filters to air dry completely in a clean environment. Once fully dry, apply air filter oil evenly to the filter media according to product specifications. Allow the oil to wick through the filter material for approximately 20 minutes before reinstalling. Ensure both filters are completely dry before applying oil, as moisture will prevent proper oil absorption.

This dual-filter cold air intake system provides improved airflow characteristics for 3.0L and 3.5L V6 C-Class engines while maintaining reliable filtration through dual high-flow filters. The system is designed to work with factory engine management components, though professional installation is recommended to ensure proper fitment and performance.
