Wix cabin air filter WP10320 — pleated micro-glass media, Viton seals, racing-tested durability

The WIX FILTR LD cabin air filter is a high-performance replacement filter featuring pleated micro-glass media and Viton seals for improved particle retention and long-lasting dirt capacity.

Built by WIX Racing Products and track-tested across demanding motorsports environments, this cabin air filter brings robust filtration technologies from racing to everyday vehicles. Its pleated micro-glass construction captures smaller particles more efficiently than standard paper filters, while Viton seals improve resistance to heat and ozone for a secure fit and extended service life. The WP10320 part is made in the United States and comes in packaging sized 11.75" x 6" x 6.67" with a lightweight 0.1-pound shipping weight.

How does this filter improve air quality inside my vehicle?

The pleated micro-glass media is engineered to trap a wide range of airborne particles, increasing the filter's dirt-holding capacity and maintaining airflow. Unlike basic cellulose filters, the micro-glass fibers are arranged to retain smaller particulates while preserving ventilation efficiency for the HVAC system.

• Pleated micro-glass media captures finer particles than standard paper elements
• High dirt-holding capacity reduces frequency of replacements under dusty conditions
• Maintains consistent cabin airflow to support HVAC performance

What makes the Viton seals important for fit and durability?

Viton seals are a synthetic rubber known for resistance to heat, ozone and many automotive chemicals, which helps keep the filter seating tight over time. A stable sealing material prevents bypass of unfiltered air and reduces the chance of leaks, ensuring the cabin receives filtered air through the life of the part.

• Viton resists deterioration from heat and ozone exposure
• Provides a reliable, long-lasting seal to prevent air bypass
• Improves fitment consistency across service intervals

How does this WIX Racing-derived filter hold up in demanding conditions?

Designed with technologies proven in stock car, dirt track and off-road racing, the filter’s construction emphasizes durability and capture efficiency under high dust loads. The pleated design increases surface area, so it can trap more contaminants before airflow becomes restricted.

• Racing-tested materials and design adapted for everyday vehicle use
• Pleated construction increases surface area and service life
• Resilient components reduce performance degradation in harsh environments

Will this part WP10320 fit my vehicle and how do I install it?
