Original MANN‑FILTER Interior Filter CU 3360 – For Passenger Cars

The MANN‑FILTER Interior Filter CU 3360 is a premium cabin air filter designed to deliver clean, healthy air inside the vehicle’s passenger compartment. Engineered with advanced filtration technology, it protects occupants from dust, pollen, and airborne pollutants while maintaining optimal airflow for climate control systems.

Key Features and Technical Specifications

• High‑Efficiency Filtration: Utilises a multi‑layer media that captures particles as small as 0.5 µm, ensuring superior protection against allergens and fine dust.
• Active Carbon Layer: Integrated activated carbon reduces odors, volatile organic compounds (VOCs), and harmful gases for a fresher cabin environment.
• Durable Construction: Made from high‑quality polypropylene housing that resists moisture, heat, and mechanical stress during installation and operation.
• Optimised Airflow: Designed to minimise pressure drop across the filter, preserving HVAC efficiency and preventing strain on the vehicle’s blower motor.
• Standardised Dimensions: Fits a wide range of passenger cars with a compact footprint, making it compatible with many OEM models.

Compatibility Overview

The CU 3360 is engineered to fit numerous popular passenger car platforms. While the exact model list varies by manufacturer, the filter is widely recognised for its compatibility with:

• Porsche models such as the 911 (996/997), Boxster, Cayman, and related variants.
• Peugeot vehicles including the 406 series (8B, 8C, 8E/F) and other passenger cars that share similar cabin air intake geometry.
• Other European passenger cars that employ a standard interior filter mounting location behind the glove compartment or under the dashboard.

For precise fitment, consult your vehicle’s service manual or the manufacturer’s part number list. The CU 3360 is often referenced by OEM codes such as 99657121901, 99657221901, and similar identifiers across different brands.

Installation Guide

1. Locate the Cabin Air Intake: Open the glove compartment or access panel behind the dashboard. The filter housing is typically situated near the rear of the passenger side cabin.
2. Remove the Old Filter: Gently pull the existing filter out, noting its orientation. Dispose of it responsibly.
3. Insert the CU 3360: Align the filter’s edge with the housing slot and slide it in until fully seated. Ensure that the airflow arrows on the filter face the correct direction.
4. Secure the Housing: Replace any retaining clips or fasteners, then close the glove compartment or panel.
5. Verify Operation: Start the vehicle and check for proper HVAC function. The cabin should feel cooler and less dusty after installation.

Maintenance Tips

• Replace the filter every 12–15 months or sooner if you drive in heavily polluted environments.
• Avoid using compressed air to clean the housing, as this can damage the filter media.
• Inspect the filter for visible debris before installation; a visibly clogged filter indicates it is time for replacement.

Benefits of Using the CU 3360

• Improved Air Quality: Reduces exposure to allergens, dust, and pollutants, enhancing driver and passenger comfort.
• Odor Control: Activated carbon layer neutralises unpleasant smells from exhaust, food, or environmental sources.
• HVAC Efficiency: Maintains optimal airflow, preventing the blower motor from working harder than necessary.
• Longevity: Durable construction extends filter life compared to lower‑grade alternatives.

Material Composition and Environmental Impact

The CU 3360’s media consists of a blend of high‑density polypropylene fibers combined with activated carbon granules. This composition offers a balance between filtration performance and environmental sustainability, as the materials are recyclable under appropriate waste management protocols.

Quality Assurance and Compliance

MANN‑FILTER is renowned for rigorous quality control processes. The CU 3360 undergoes:

• ISO 9001 Certification: Ensures consistent manufacturing standards.
• Performance Testing: Validates particle capture rates, airflow resistance, and durability under simulated operating conditions.
• Compliance with Automotive Standards: Meets or exceeds OEM specifications for cabin air filters in European markets.

Conclusion

The Original MANN‑FILTER Interior Filter CU 3360 stands out as a reliable, high‑performance solution for maintaining pristine cabin air across a broad spectrum of passenger vehicles. Its blend of advanced filtration media, active carbon technology, and robust construction delivers lasting protection against airborne contaminants while preserving HVAC efficiency. For drivers who prioritise comfort, health, and vehicle performance, the CU 3360 is an essential component in any routine maintenance regimen.
