MANN‑FILTER Air Filter C 24 021 – For Passenger Cars

The MANN‑FILTER Air Filter C 24 021 is a premium engine air filter designed specifically for passenger cars that require the C 24 021 size. It delivers exceptional filtration performance, ensuring that only clean, dust‑free air reaches the combustion chamber. This protects the engine’s internal components, improves fuel efficiency, and extends overall vehicle longevity.

Key Features

• High‑Efficiency Filtration: The filter uses a multi‑layer media that captures fine particles down to 0.5 µm, preventing wear on pistons, valves, and bearings.
• Durable Construction: Made from high‑quality polypropylene housing with reinforced edges, the filter resists cracking and maintains shape under pressure changes.
• Low Air Resistance: The design balances filtration with airflow, keeping pressure drop below 5 Pa to avoid compromising engine performance.
• Easy Installation: Snap‑fit mounting system fits most OEM and aftermarket housings that accept the C 24 021 size. No special tools required.
• Long Service Life: Under normal driving conditions, the filter can last up to 12 months or 10,000 km before needing replacement.

Compatibility Overview

The C 24 021 designation is a standard size used by many manufacturers. The filter fits seamlessly into:

• Honda Civic (all variants from IX to Tourer)
• Acura models that share the same engine bay dimensions
• Other passenger cars with a 24 mm diameter and 21 mm depth requirement

Because of its universal shape, it is also used in various aftermarket and OEM filter housings worldwide.

Installation Guide

1. Locate the existing filter: Open the hood and find the air intake assembly. The filter sits inside a rectangular housing with a removable cover.
2. Remove the old filter: Unscrew or unclip the housing cover, then lift out the worn filter. Dispose of it responsibly.
3. Prepare the new filter: Remove any protective packaging and check for correct orientation (the side marked “+” should face the engine).
4. Insert the filter: Place the C 24 021 into the housing, ensuring a snug fit. The snap‑fit tabs will lock it in place.
5. Reassemble: Replace the cover and secure it with screws or clips. Verify that all connections are tight to prevent air leaks.

Maintenance Tips

• Check the filter every 6 months or after heavy driving conditions (dusty roads, off‑road use).
• Clean the housing with a damp cloth before installing a new filter to remove accumulated debris.
• Avoid using compressed air directly on the filter media; it can damage the fine layers.
• Store spare filters in a dry, cool place to preserve their integrity.
