Airaid Kit Replacement Filter - 721-472

The Airaid 721-472 Kit Replacement Air Filter is a direct-fit, universal clamp-on performance air filter designed to serve as a replacement for compatible Airaid cold air intake and performance air intake systems. Whether you're refreshing an aging intake kit or upgrading your existing filtration, the 721-472 delivers the dryflow filtration technology Airaid is known for — no oil required, no mess, and long-lasting reusability. If your current Airaid intake system calls for this filter or you're building a custom intake setup that accepts an oval tapered clamp-on filter, this is a high-quality, purpose-built solution.

Key Features & Benefits

• Dryflow Filtration Technology: Airaid's dry synthetic filter media requires no oil to function, eliminating the risk of over-oiling and potential MAF sensor contamination — a common concern with oiled aftermarket filters.
• Washable & Reusable: Unlike disposable OEM-style paper filters, the 721-472 can be cleaned and reinstalled, making it a long-term investment rather than a recurring expense.
• Oval Tapered Clamp-On Design: The oval tapered shape is engineered for compatibility with specific Airaid intake kit housings and universal clamp-on applications, ensuring a secure, airtight seal.
• Multi-Layer Construction: The filter uses a multi-layer media design to balance airflow with filtration efficiency — helping your engine breathe more freely while still protecting internal components from harmful debris.
• Made in the USA: Manufactured domestically, the 721-472 is built to Airaid's quality standards with materials and construction overseen in American facilities.
• Lifetime Filter: With proper maintenance, this filter is designed to last the life of your vehicle, reducing long-term ownership costs compared to disposable alternatives.
• Not CARB Legal: This filter is not California Air Resources Board (CARB) compliant and is not for sale or use in California — an important consideration if you live in or regularly operate in CA.
