Wix Racing Panel Air Filter — Vehicle-Specific 4" Low-Profile, 675 CFM High-Flow

WIX Racing Filters Air Filter Panel is a vehicle-specific panel filter engineered to deliver smooth airflow up to 675 CFM while fitting factory intake housings.

This WIX Racing panel filter combines a low-restriction media design with a compact 4-inch profile to replace or upgrade your vehicle’s stock air filter. It’s classified as class "a" with a light-duty (ld) designation, making it suitable for daily driving and spirited road use where reliable airflow and filtration balance are required. The panel form factor ensures a direct fit in many factory airboxes, simplifying installation without modifications.

How does this filter improve airflow compared with a standard paper element?

The WIX Racing panel is built to prioritize airflow while still capturing contaminants, offering up to 675 cubic feet per minute (CFM) of airflow in its design rating. That higher flow capability helps reduce intake restriction so the engine can breathe more freely under load and throttle demands.

• Rated airflow: 675 CFM for improved intake flow.
• Panel shape: fits factory housings for minimal installation effort.
• Low-profile height: 4.00 inches to match constrained airbox spaces.

What are the key physical and fit specifications I should know?

This filter has a compact 4-inch height suited to many vehicle-specific applications and is categorized as class "a" for its construction. The product is designated for light-duty use and is intended as a direct-fit replacement — check vehicle compatibility to confirm exact fitment.

• Height: 4.000 inches for tight airbox clearance.
• Fit type: vehicle-specific—verify fitment against make/model/year.
• Duty type: ld (light-duty), designed for everyday and performance street use.

How do I install and maintain the WIX Racing panel filter?

Installation is straightforward: remove the factory element from the airbox and place the WIX Racing panel in the same orientation, ensuring a proper seal around the housing perimeter. Maintenance recommendations typically include periodic inspection and replacement according to driving conditions rather than cleaning, since panel filters are commonly designed as service-replacement elements.

• Installation: direct replacement into existing factory airbox.
• Maintenance: inspect regularly; replace at service intervals or when dirty.
• Service tip: confirm seal and orientation to prevent unfiltered air entry.

What performance trade-offs should I expect with this panel filter?

The WIX Racing panel balances airflow and filtration rather than maximizing one at the expense of the other, so you’ll gain better breathing than many stock elements without a major sacrifice in particle capture. It’s optimized for everyday and performance street driving rather than extreme off-road or motorsport environments where different media or serviceability would be preferred.

• Balance: improved airflow with effective filtration for street use.
• Not intended: extreme-duty or reusable-cleanable racing-only applications.
• Compatibility: designed to maintain factory housings and sensors alignment.

Who is this for: Drivers who want a straightforward, vehicle-specific upgrade to their stock air filter—particularly those seeking a cleaner, less restricted intake without modifying the airbox. If you prioritize a plug-and-play replacement that supports daily driving and occasional spirited use, this WIX Racing Filters Air Filter Panel is a practical choice. Confirm vehicle compatibility before purchase to ensure correct fit and sealing.
