Airaid Kit Replacement Filter - 720-476

The Airaid 720-476 Kit Replacement Filter is a high-flow performance air filter engineered to help improve horsepower and torque by optimizing airflow and reducing restriction through the powerband. Designed as a direct replacement for Airaid intake kits that originally spec this filter, the 720-476 makes it easy to restore your cold air or short ram intake system to peak performance without replacing the entire kit. Whether you're refreshing a high-mileage intake or simply staying on top of preventative maintenance, this SynthaFlow-style filter from Airaid delivers the same performance-oriented filtration your system was built around.

Key Features & Benefits

• High-Flow Performance Filtration: Engineered to increase airflow compared to a restrictive OEM paper filter, helping your engine breathe more freely and supporting stronger performance across the RPM range.
• Designed to Improve Horsepower & Torque: Airaid's filter construction is specifically optimized to reduce intake restriction — a known limiting factor for power output — making this an upgrade-level replacement, not just a serviceable swap.
• Drop-In Kit Replacement Fitment: Built to replace the filter in compatible Airaid intake kits, so there's no modification, adapter, or fabrication required. It installs exactly where your original filter lived.
• Reusable Construction: Unlike disposable paper filters, Airaid performance filters are designed to be cleaned and re-oiled, reducing long-term cost of ownership and keeping landfill waste down.
• Proposition 65 Compliance Noted: This product carries a California Proposition 65 warning and is not CARB legal — it is not intended for sale or street use in California.

Fitment

The Airaid 720-476 is a universal kit replacement filter intended to service or replace the filter element in specific Airaid cold air intake and short ram intake kits. It is not a universal bolt-on for every vehicle — it is designed to match the filter housing dimensions used in compatible Airaid intake systems. If you're unsure whether this filter fits your specific Airaid intake kit, use the fitment checker on this page or contact the ThreePiece.us team directly before ordering. Because fitment depends on your existing Airaid intake kit rather than your vehicle's year/make/model alone, verifying the original kit's filter part number is the most reliable confirmation step.

Important: This filter is not CARB legal and is not available for sale or street use in the state of California.

Frequently Asked Questions

Q: Is this filter a direct OEM replacement or an aftermarket performance upgrade?
A: The Airaid 720-476 is a kit replacement filter — meaning it's designed to replace the filter element inside a compatible Airaid performance intake kit. It is an aftermarket, high-flow filter, not an OEM paper filter. If your vehicle still has its factory airbox, this filter is not a direct drop-in for that application.

Q: Can I buy this filter if I live in California?
A: No. The Airaid 720-476 is not CARB legal and is not for sale in California. This is a Proposition 65 product. If you're in California, please contact our team to discuss compliant alternatives.

Q: Is this item in stock or does it require a lead time?
A: The 720-476 is a regularly stocked product at ThreePiece.us — no special order wait time required.

Q: How do I confirm this is the correct replacement filter for my Airaid intake kit?
A: The best way to confirm fitment is to check the part number on your existing Airaid intake kit documentation or the filter itself, and match it to MPN 720-476. You can also use the fitment checker on this product page or call our team at 813-535-5801 — we're happy to help verify compatibility before you place your order.
