Decent, but it's tough on the environment.

TL;DR Disposable OEM-spec panel filter from Toyota's own supplier, confirmed to fit the 5th gen 4Runner via community reviews spanning 2013, 2018, and 2022 model years at meaningful savings vs. dealer pricing. The 143-3025 preserves the original Toyota 17801-38051 specification (full depth plus pre-filter layer) that Toyota itself downgraded when they switched to the shorter YZZ13 replacement.
The 143-3025 is a disposable pleated paper/synthetic multi-layer panel filter built by Denso to OEM specification for Toyota 1GR-FE 4.0L V6 applications (5th gen 4Runner, FJ Cruiser, Lexus GX460). It replaces Toyota part 17801-38051, an OEM number Toyota has since superseded with the shorter YZZ13 variant. Community owners document that the YZZ13 omits the pre-filter layer and is physically shorter; the 143-3025 matches the original full-depth spec. No named test standard (ISO 5011 or SAE J726) has been published for this SKU. The 15,000-mile OEM service interval is confirmed across a well-rated owner base with no documented premature clogging. Fitment is confirmed at sixityauto.com against the Toyota 17801-38051 OEM cross-reference; community reviews confirm correct installation in 2013, 2018, and 2022 4Runner models.
Right pick for a 5th gen 4Runner (2010-2018 confirmed; 2019-2024 community-supported but cross-reference database verification for those years is incomplete), FJ Cruiser, or GX460 owner who wants the original OEM specification at roughly half the dealership price. Skip if your 4Runner is a 2025 or newer (6th gen TNGA-F platform with a turbocharged four-cylinder and a completely different air box) or if you want independent ISO 5011 test data before purchase; a published-data OEM-supplier alternative (Wix or equivalent with spec sheets) would satisfy that requirement.
Passive replacement filter with no chemical exposure during installation or removal; no SDS applies. The environment score of 4 reflects the disposable lifecycle: this filter generates physical waste at each 15,000-mile replacement interval, with composite media and frame construction that is not recyclable in standard municipal programs. For washable reusable alternatives that eliminate multiple replacement cycles, see K&N or aFe filters listed for the same application.
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'll show the filters that fit it, ranked by our independent score and cross-checked against multiple catalog fitment sources.
Multiple owners confirm fitment in 2022 4Runner. The 5th gen 4Runner uses the same 1GR-FE 4.0L V6 and air box throughout its production run (2010 onward). However, independent cross-reference database confirmation for 2019-2024 model years has not been verified against RockAuto or AutoZone separately from community reviews · check a parts database for your specific year before purchasing.
The 143-3025 replaces Toyota 17801-38051. Toyota has superseded that number to 17801-YZZ13, which is physically shorter and does not include the pre-filter layer. Community reviews document that the Denso 143-3025 preserves the original 17801-38051 specification · full depth and pre-filter included.
A 2022 Lexus GX460 fitment is community-confirmed. The GX460 uses a different engine (1UR-FE 4.6L V8) than the 4Runner · fitment for the GX460 application is community-confirmed but has not been independently verified in a cross-reference database. Confirm against RockAuto or AutoZone for your specific year.
This is a documented discrepancy. Community comparison between the China-made Denso filter and the original Japan-made version found construction to be equivalent except for slightly lower density on the pre-filter layer. The community assessment is that build quality is effectively identical to OEM despite the origin discrepancy.
