Wix Engine Air Filter for Lexus & Toyota (2007–2018) — 49310 High-Efficiency Single Unit

The WIX 49310 is a high-efficiency replacement engine air filter designed to reduce airborne contaminants and help preserve engine performance for select Lexus and Toyota models (2007–2018).

WIX engineered this air filter to provide durable filtration and reliable sealing for engines that require precise airflow and contaminant control. Built with embossed pleats, pleat stabilization beads and heat-resistant plastisol seals, the 49310 targets dust and particulates before they enter the intake system, supporting consistent operation and helping extend service intervals when used with routine maintenance.

How does the WIX 49310 protect my engine?

The filter media captures dust and particles while pleat stabilization prevents collapse under airflow, keeping debris out of the intake and away from sensitive engine components. A proper seal prevents bypass so only filtered air reaches the engine.

• Embossed pleats increase surface area for dirt-holding capacity
• Pleat stabilization beads maintain shape under pressure
• Heat-resistant plastisol top and bottom seals ensure an accurate fit
• Designed to limit contaminant entry into the lubricating system

Will this filter fit my Lexus or Toyota?

WIX 49310 is specified for a range of Lexus and Toyota applications from model years 2007–2018, but fitment can vary by engine and trim. Always confirm compatibility using your vehicle’s year, make, model and engine options before purchasing.

• Check the part finder or vehicle lookup to confirm fit
• Some vehicles require two filters—this listing is for a single unit
• Compare dimensions and seal style to your existing filter if unsure
• Refer to the owner’s manual for manufacturer service recommendations

How often should I replace the WIX 49310?

Replacement interval depends on driving conditions: dusty or off-road use shortens service life, while normal highway driving may allow longer intervals. Follow manufacturer guidance and inspect the filter periodically for visible dirt, damage or airflow restriction.

• Inspect at regular service intervals or when performing scheduled maintenance
• Replace sooner if operating in dusty, sandy, or polluted environments
• Typical replacement follows the vehicle maker’s maintenance schedule
• Replacing a clogged filter can restore proper airflow and efficiency

What are the construction highlights of this WIX replacement filter?

WIX combines robust materials and assembly features to produce a filter that resists deformation and maintains a secure seal under engine bay heat and airflow. These design choices help the filter capture more particulates while remaining durable over time.

• Embossed filter media for increased dirt-holding and longevity
• Pleat stabilization beads to preserve media spacing and airflow
• Plastisol seals engineered for heat resistance and pliability
• Single-filter packaging—verify if your vehicle needs multiple units

Who is this for? WIX 49310 is meant for owners and technicians replacing the engine air filter on compatible Lexus and Toyota models from 2007 to 2018 who want an OEM-quality aftermarket option. It’s suitable for drivers looking for dependable filtration, durable construction and an accurate sealing fit—particularly those who perform routine maintenance, drive in mixed environments, or want a straightforward replacement part verified against their vehicle’s specifications.
