Key Features:

This K&N Drop In Air Filter combines advanced filtration technology with user-friendly design. Key features include:

• High airflow capacity of up to 900 cubic feet per minute (cfm) for improved engine breathing
• Potential power gains of up to 15 horsepower by reducing intake restriction
• Reusable and washable design for long-term cost savings and environmental benefits
• Pre-oiled surgical cotton fabric that captures contaminants effectively while maintaining airflow
• Aluminum mesh support structure that protects the filter media and maintains shape
• Direct-fit replacement for the factory air filter, requiring no modifications
• Can tolerate up to 1/4 inch of debris buildup before cleaning is necessary
• Improves airflow by straightening tumbling air inside the intake system

Construction & Design:

The K&N Drop In Air Filter features a multi-layered construction that balances filtration efficiency with airflow enhancement. The core filtration media is a surgical-grade cotton fabric that is specially treated with oil to trap dirt and particles effectively. This cotton layer is sandwiched between a sturdy aluminum wire mesh, which provides structural integrity and prevents deformation under airflow pressure.

The design also incorporates a unique airflow straightening effect. As air passes through the filter, the cotton’s porous structure catches tumbling air currents and aligns them into a straighter flow path. This results in faster-moving air entering the engine, which can improve combustion efficiency and overall performance.

Performance & Sound

By reducing intake air restriction, this K&N air filter can deliver noticeable power improvements, with gains of up to 15 horsepower reported on compatible setups. The enhanced airflow also contributes to a more responsive throttle feel. While the filter itself does not significantly alter engine sound, improved breathing can subtly enhance the induction noise, providing a sportier driving sensation.

Installation & Fitment:

Installation is straightforward and designed to be a direct replacement for the factory air filter in the 2003 to 2005 Dodge Neon SRT-4. No special tools or modifications are required, making it an ideal upgrade for enthusiasts of all skill levels. Simply remove the old air filter and insert the K&N Drop In Air Filter into the existing airbox. The filter comes pre-oiled and ready to use right out of the box.
