SPEARHEAD Max Thrust Engine Air Filter MT-343 — Direct-Fit for Toyota LX570/Land Cruiser & Sequoia/Tundra, High Dust Capacity

The SPEARHEAD Max Thrust MT-343 is a direct-fit replacement engine air filter engineered to trap more dust while maintaining strong airflow for compatible Toyota V8 models.

If your LX570, Land Cruiser, Sequoia or Tundra has lost throttle responsiveness or fuel efficiency, a clogged or undersized air filter is often the culprit. The Max Thrust MT-343 replaces the factory unit with a higher-capacity pleated media element designed to hold more debris without restricting intake air, helping the engine breathe more freely for up to recommended service intervals.

How does this filter improve everyday driving?

This replacement uses a multi-layer, hexagonal pleat construction that increases surface area for trapping contaminants while preserving unrestricted airflow. Drivers can notice steadier throttle response and more consistent engine performance compared with a worn or standard paper filter.

• Hex-D pleat pattern increases filter area and dust capacity
• Progressive fine media captures both large particles and fine dust
• Designed to maintain airflow as the element collects debris

Will the MT-343 fit my vehicle and is it easy to install?

The MT-343 is manufactured to match OEM dimensions for select Toyota V8 models, providing a snap-in replacement for the original air filter. Installation is a simple, do-it-yourself service that usually requires only opening the airbox and swapping the element—no special tools required.

• Direct fit for LX570 and Land Cruiser model years 2008–2011 and 2013–2021
• Compatible with Sequoia 2008–2013 and Tundra 2007–2009 (4.7L/5.7L) and select 2011–2012 Tundra applications
• Not compatible with Tundra 4.0L V6—verify year/make/model before purchase

How long does the filter last and how does it affect maintenance intervals?

The Max Thrust is designed to perform reliably through normal driving cycles and is specified for service intervals comparable to or better than many stock filters. While lifespan depends on driving conditions and environment, the filter’s increased holding capacity helps extend useful life between changes under typical conditions.

• Engineered for extended dust-holding versus standard filters
• Recommended replacement is based on driving environment and mileage
• Inspect at routine service intervals and replace when heavily soiled

What performance benefits can I expect after fitting this filter?

Replacing an old, restricted filter with the Max Thrust can return lost responsiveness and stabilize fuel economy by restoring proper intake air volume. The design focuses on holding more contaminants without sacrificing airflow, which supports smoother combustion and throttle feel.

• Helps restore throttle response lost to clogged filters
• Supports consistent engine breathing and efficiency
• Offers a cost-effective maintenance upgrade over stock elements

Who is this for: The SPEARHEAD Max Thrust MT-343 is for owners of compatible Toyota LX570, Land Cruiser, Sequoia and Tundra V8 models who want an easy, direct-fit air filter upgrade. It’s especially suited to drivers in dust-prone areas, higher-mileage vehicles, or anyone seeking a higher-capacity replacement without changing intake hardware. Always confirm fitment against your vehicle year, make and model before ordering.
