RYANSTAR RACING 76mm (3") High-Flow Cone Air Filter Dust Cove — Closed-Top, Durable Polyester Protection

This universal dust cove is built to fit 3" (76mm) diameter cone filters and extend filter life by blocking coarse dirt, leaves, and grit before they reach the filter media. Made from durable polyester with stitched elastic openings, it installs in seconds and works in a variety of temperatures without losing function. The design prioritizes protecting the filter element while maintaining the performance advantages of a high-flow cone intake.

How does the dust cove protect my air filter during everyday driving?

The cover acts as a first line of defense, catching larger particles and keeping them from lodging between the metal mesh and filter material. By preventing those contaminants from embedding in the filter, it reduces the frequency of deep cleanings and potential airflow restriction.

• Blocks coarse debris, leaves, and road grit before the filter media.
• Helps prevent particles from getting stuck between mesh and filter layers.
• Reduces the need for premature filter servicing or replacement.

Will the cover affect engine airflow or performance?

RYANSTAR designed the cove to preserve high-flow characteristics while screening out large contaminants. It covers the outer surface of the cone filter without compressing the pleats, helping maintain intake velocity and throttle response where the original filter flow matters.

• Fitted to 3" (76mm) diameter cone filters for minimal flow restriction.
• Thin, breathable polyester allows air to pass while stopping debris.
• Closed-top shape keeps the crown area protected without blocking intake.

How easy is it to install and care for the RYANSTAR dust cove?

Installation takes seconds — simply stretch the elastic opening over the cone filter’s outer edge and smooth it into place. The stitched elastic keeps it secure under vibration, and the polyester fabric is simple to rinse or brush clean when necessary.

• Slip-on design with stitched elastic for quick fitting.
• Durable polyester is washable and dries quickly.
• No special tools required; reuse after cleaning.

What sizes and environments is this cover suitable for?

The product fits most 3-inch (76mm) cone-style intake filters and performs in a wide range of environments, including dusty roads and colder climates where the material remains functional. Its universal sizing and stretch allow compatibility with many aftermarket filters used on cars, motorcycles, ATVs, and other small-engine applications.

• Designed for 3" (76mm) diameter cone filters; length ~6.26" overall compatibility.
• Works in cold temperatures without losing protective function.
• Suited for street, off-road, and mixed-use conditions.

Who is this for? Vehicle owners and mechanics who use aftermarket cone-style intake filters and want a low-cost, easy-to-fit way to reduce filter contamination and extend service intervals. Ideal for daily drivers in dusty areas, weekend off-road riders, and anyone looking to protect their intake without sacrificing airflow or performance.
