TL;DR Disposable pleated-paper OEM replacement made by MANN+HUMMEL (the Tier 1 OEM filtration supplier behind WIX and NAPA Gold) with drop-in fit confirmed for the 2010-2024 Toyota 4Runner 4.0L V6. The >= 99% ISO 5011 filtration efficiency figure is manufacturer-published with no independent consumer-lab test for this specific SKU, which keeps the score honest rather than exceptional.
The WIX 49350 is a disposable pleated-paper filter using phenolic-resin-treated cellulose media with pleat stabilization beads; the same construction Toyota specifies as OEM. WIX is manufactured by MANN+HUMMEL, a Tier 1 OEM supplier, which is why the filtration efficiency claim (>= 99% at ISO 5011 medium test dust) carries more credibility than a typical aftermarket marketing assertion. No independent consumer-lab test for this specific retail SKU exists in the reviewed evidence base. The OEM cross-reference to Toyota 17801-0W010 is confirmed across RockAuto, AutoZone, and NAPA; community reviews spanning 2010 through 2023 4Runner model years confirm drop-in fit and a solid seal in the factory air box. Replacement interval follows Toyota's OEM recommendation: 15,000-30,000 miles depending on duty cycle.
Right pick for a 5th gen Toyota 4Runner, Lexus GX460, or FJ Cruiser owner who wants an OEM-quality replacement at below-dealer pricing; the filter's manufacturer (MANN+HUMMEL) supplies the OEM production line for the same platform. Skip if your 4Runner is a 6th generation (2025+); the newly redesigned platform uses a different engine and air box, so verify the part number against your specific model year. Also skip if you are switching from a K&N washable filter and prioritizing long-term cost savings over replacement cycles; a washable reusable filter eliminates the disposable replacement cadence entirely at a higher upfront cost.
Passive replacement component with no chemical exposure during installation or removal; no SDS applies. Environment score of 4 reflects a standard disposable filter lifecycle: a single-use paper-and-cardboard unit replaced on the OEM 15,000-30,000 mile service interval, with composite construction (cellulose media, cardboard frame, plastisol seal) that goes to landfill at replacement with limited municipal recyclability.
An engine air filter only does its job if it actually fits your car, and the same vehicle often takes a different part year to year. Before you buy, find the engine air filter for your vehicle in the CarCareTruth air-filter finder -- pick your year, make, and model and we will show the filters that fit it, ranked by our independent score and cross-checked against multiple catalog fitment sources.
Yes; the WIX 49350 is confirmed for the Toyota 4Runner 2010-2024 (4.0L V6, 5th generation). It cross-references to OEM Toyota part 17801-0W010 and is verified against RockAuto, AutoZone, and NAPA application databases. Community reviews for 2010 through 2023 model years confirm drop-in fit in the air box. Always verify with your specific year, make, model, and engine before purchase.
Yes; the WIX 49350 also fits the Lexus GX460 2010-2023. The GX460 shares the 4.0L V6 engine and air box design with the 5th gen 4Runner.
WIX is owned by MANN+HUMMEL Group, a Tier 1 OEM filtration supplier that manufactures filters for multiple vehicle manufacturers. WIX and NAPA Gold filters are made by the same manufacturer; WIX makes NAPA Gold equivalents as part of the same production line.
Toyota specifies 15,000-30,000 miles depending on driving conditions; lighter-duty highway driving can reach the longer end, dusty or off-road conditions warrant the shorter interval. WIX defers to the OEM recommendation. Check your owner's manual for the specification for your driving conditions.
The Amazon listing for WIX Filters 49350 Engine Air Filter carries a California Prop 65 warning. California requires this warning on a very wide range of manufactured goods — including rubber, vinyl, plastic, and metal automotive parts — whenever trace exposure to any of roughly 900 listed substances (commonly phthalates or heavy metals) is possible, regardless of whether the specific product poses a meaningful health risk. As a passive accessory, WIX Filters 49350 Engine Air Filter has no Safety Data Sheet, so there's no chemistry breakdown to translate beyond that.
