RYANSTAR RACING 4-Inch Cone Air Filter 102mm Inlet, 231mm Tall — High-Flow Washable Reusable

RYANSTAR RACING's 4-inch cone air filter is a washable, reusable high-flow intake filter with a 102mm inlet and 231mm height designed to improve airflow and throttle response for many vehicle applications.

This cone-style filter is built to be a universal, clamp-on upgrade for aftermarket intakes, carburetors or custom setups that accept a 102mm (4 inch) diameter. Crafted from layered mesh and durable materials, it aims to deliver better airflow while still filtering contaminates, and it includes a stainless-steel clamp for secure, tool-free installation. The compact 231mm height keeps the filter manageable in tight engine bays while offering the conical surface area needed for increased airflow compared with flat panels or restrictive stock units.

How does this cone filter affect engine breathing and throttle response?

The conical geometry and two-layer mesh are engineered to reduce intake restriction and increase the volume of air available to the engine at higher throttle openings. Improved airflow can translate to faster turbo spool or crisper throttle response without changing engine internals.

• 4-inch (102mm) inlet fits common aftermarket intakes and carburetor necks.
• 231mm height provides increased filter surface area in a compact form.
• Two-layer mesh design balances filtration and free flow.
• Washable and reusable construction maintains performance over time.

Is the RYANSTAR RACING cone filter easy to install and maintain?

Yes — the filter ships with a stainless-steel clamp and an adjustable fitting that allows clamp-on attachment to a variety of intake necks. Cleaning is straightforward: remove, wash the mesh per the manufacturer's care instructions, dry, and reinstall for renewed filtration efficiency.

• Includes stainless-steel clamp for secure mounting.
• Adjustable diameter simplifies fitment on non-exact neck sizes.
• Washable and reusable material lowers long-term ownership costs.
• No special tools required for most installations.

What materials and construction quality can I expect?

The filter combines a durable outer mesh with an inner filtration layer to withstand road use and repeated cleanings. Corrosion-resistant hardware like the included stainless-steel clamp contributes to long-lasting performance even in wet or salty environments.

• Two-layered mesh for structural strength and filtration balance.
• High-quality materials and manufacturing techniques for durability.
• Stainless-steel clamp resists rust and maintains clamping force.
• Designed for repeated wash-and-reuse cycles without rapid degradation.

Which vehicles and setups are compatible with this filter?

The 102mm inlet makes this cone filter suitable for many universal intakes, carburetors, ducted cold-air systems and custom-fabricated setups. Because it’s a universal product, adapters or small modifications to the intake neck may be needed for a perfect fit.

• Works for aftermarket intakes and many performance carburetor necks.
• Good for bikes, cars, ATVs and custom projects that accept a 4-inch inlet.
• Ideal where compact height (231mm) is required by tight engine bays.
• Adapters can improve fit on non-standard diameters.

Who is this for? RYANSTAR RACING’s 4-inch cone air filter is aimed at DIY mechanics, performance hobbyists and anyone fitting a universal intake or building a custom induction system who wants a compact, washable filter that balances airflow with reusable filtration. It’s especially useful when you need a 102mm inlet size, reliable clamp-on mounting, and a durable, two-layer mesh design for repeated use.
