Airaid Kit Replacement Filter - 723-478

The Airaid 723-478 Kit Replacement Filter is a direct-fit replacement air filter designed to restore peak airflow performance to your existing Airaid intake system. If your current Airaid intake filter has accumulated miles of dust, dirt, and debris, swapping in the 723-478 is the most cost-effective way to bring your induction system back to like-new condition — without replacing the entire intake kit. Keeping your air filter fresh is one of the simplest maintenance steps you can take to protect your engine and maintain the performance gains your Airaid intake was designed to deliver.

Key Features & Benefits

• Direct OEM-Style Replacement: The 723-478 is engineered specifically to replace the filter in select Airaid intake kits, ensuring a precise, no-modification fit so you spend less time in the garage and more time on the road.
• Restored Intake Airflow: A fresh, clean filter removes the restriction caused by a clogged or worn-out element, helping your engine breathe freely and maintain the throttle response and efficiency your Airaid system was tuned for.
• Airaid Quality Construction: As a genuine Airaid product, this replacement filter is built to the same quality standards as the filter that came with your original intake kit — so you're not compromising on materials or filtration efficiency when you swap it in.
• Cost-Effective Maintenance: Replacing just the filter element rather than purchasing a new full intake kit saves money while fully refreshing your system's filtration capability.
• Protects Your Engine Investment: Proper filtration is your engine's first line of defense against harmful particulates. Replacing a worn filter on schedule helps prevent premature wear on internal engine components.

Frequently Asked Questions

Q: Is the Airaid 723-478 a replacement for my entire intake kit, or just the filter?

A: The 723-478 is a replacement filter element only — it is designed to replace the air filter within a compatible Airaid intake kit, not the full intake system (tubing, couplers, heat shield, etc.). If you need a complete intake kit, that would be a separate product.

Q: How do I know if the 723-478 fits my Airaid intake kit?

A: The best way to confirm compatibility is to cross-reference your existing Airaid intake kit's part number with Airaid's replacement filter listings, or contact our fitment team at ThreePiece.us. We can help you match the correct replacement filter to your specific kit before you place your order.

Q: Can I use the Airaid 723-478 as a replacement for a non-Airaid intake system?

A: This filter is engineered to fit specific Airaid intake kit configurations. Using it with a different brand's intake system is not recommended, as dimensions and mounting style may not be compatible. Always verify fitment for your specific application.

Q: Does free shipping apply to this filter?

A: Yes — ThreePiece.us offers free shipping on every order, including the Airaid 723-478. Affirm financing is also available at checkout if you'd like to split the cost over time.
