How does this 4-inch cone filter boost performance?

Improved airflow reduces intake restriction, allowing the engine to breathe more efficiently under load. That can lead to smoother throttle response and potential modest gains in acceleration when paired with a compatible intake and proper tuning.

• 102mm (4-inch) inlet for higher volume air passage
• Pleated filter media increases surface area for flow
• Two-layer mesh captures larger particles while preserving airflow

Is the filter easy to install and maintain?

The RYANSTAR RACING cone filter comes with an adjustable diameter base and a stainless-steel clamp for straightforward attachment to most intake pipes. It is washable and reusable, so upkeep is simple: remove, clean, dry, and re-oil (if applicable) to restore filtration performance.

• Adjustable base fits a range of pipe sizes with the included clamp
