Wix Racing Filters high-flow panel air filter — 4.0" low-profile, 675 CFM, vehicle-specific fit

WIX Racing Filters Air Filter Panel is a vehicle-specific high-flow panel filter engineered to deliver up to 675 CFM of airflow in a compact 4-inch height package.

Designed for drivers and tuners who need a performance-grade intake filter that fits specific airbox footprints, this WIX Racing panel balances unrestricted airflow with a durable construction suitable for light-duty applications. The product comes classified as Class A with a low-duty (LD) rating, and its panel style ensures compatibility where original equipment requires a flat, rectangular element.

How does this panel filter affect engine breathing during spirited driving?

The WIX Racing panel increases airflow capacity compared with many OE paper elements, helping the intake system draw air more freely under load. It supports higher volumetric flow without a bulky height profile, which can improve throttle response in engines matched to its flow characteristics.

• Rated maximum flow: 675 cubic feet per minute (CFM) for strong air delivery.
• Compact 4.000-inch height fits low-profile airboxes and tight engine bays.
• Panel geometry preserves a broad filter area for steady airflow at higher RPMs.

Will this filter fit my vehicle and how easy is installation?

This WIX Racing panel is manufactured as a vehicle-specific fit, meaning it matches the dimensions and sealing surfaces for select applications rather than being a universal element. Installation is typically straightforward: remove the old panel, place the WIX element into the airbox, and re-secure the lid—no modifications required when matched to the correct part number.

• Fit type: Vehicle Specific—confirm compatibility before purchase.
• Panel shape designed to align with factory seals and clips.
• Tool-free or basic-tool swap depending on the vehicle's airbox fasteners.

What are the construction and duty characteristics of this WIX Racing panel?

The filter is built to meet Class A standards for filtration performance while carrying a light-duty (LD) designation, making it well suited for everyday driving and occasional spirited use. Although listed capacity in grams is shown as 0.00 in the specification sheet, the crucial measurable here is airflow and fitment, with the panel optimized for unrestricted intake flow.

• Class: A — intended for consistent filtration performance.
• Duty type: LD (light-duty) for street and mild performance driving.
• Compact dimensions maintain factory intake packaging and placement.

How does the panel compare to other filter types for maintenance and longevity?

Panel filters are typically easier to replace than some conical or cylindrical aftermarket filters because they sit in the same orientation as OEM elements. Service intervals depend on driving conditions; in dusty environments swap intervals shorten, while clean-road driving extends usable life.

• Simple replacement process mirrors stock element changes.
• Recommended inspection during routine service; replace when visibly dirty or according to vehicle maintenance schedule.
• Designed to preserve airflow with minimal added intake restriction over time.

Who is this for: The WIX Racing Filters Air Filter Panel is aimed at vehicle owners and performance-minded drivers who need a direct-fit, high-flow panel element for specific car or truck models. It suits those who want improved intake airflow without altering the intake packaging, prefer OEM-style replacement serviceability, and require a Class A, light-duty filter for street and mild-performance use.
