SPEARHEAD Engine Air Filter MT-242 — Direct-Fit Replacement for Ford/Lincoln/Mazda with High Dust Capacity and Improved Airflow

The SPEARHEAD Max Thrust Engine Air Filter (MT-242) is a direct-fit replacement filter engineered to deliver higher dust-holding capacity and improved airflow for select Ford, Lincoln, Mazda and Mercury models from 2007–2023.

This high-capacity replacement air filter swaps in where the original filter fits and is built to trap more dirt without choking airflow. SPEARHEAD’s Hex-D pleat design and layered media aim to extend service intervals and help restore throttle response and fuel efficiency lost to a clogged factory filter. The MT-242 is sized and shaped to match OEM mounting points so installation requires only basic tools and minimal time.

How does the Max Thrust filter improve engine performance?

The Max Thrust filter focuses on maintaining steady airflow while capturing greater amounts of contaminants. Cleaner air reaching the intake helps the engine run with less restriction, which can improve responsiveness and consistency during acceleration.

• Hex-D pleat geometry increases surface area for airflow and dirt storage.
• Multi-layer media traps progressively finer particles without blocking flow.
• Designed to reduce the load on the intake system compared with clogged stock filters.

How long will one filter last and when should I replace it?

SPEARHEAD designs the MT-242 to maintain performance up to typical service intervals; many drivers will see effective filtration and airflow up to around 15,000 miles under normal conditions. Replace sooner in dusty or heavy-stop driving environments or if inspection shows significant debris buildup.

• Typical useful service: up to 15,000 miles in normal driving.
• Inspect at each oil change for heavy dust, oil contamination, or damage.
• Shorten interval for off-road, dusty, or commercial service use.

Which vehicles and engine types does MT-242 fit?

The MT-242 is manufactured as a direct OEM-style replacement for a wide range of Ford, Lincoln, Mazda and Mercury vehicles across multiple model years. Check the compatibility notes carefully for engine-specific and hybrid exclusions to ensure a correct fit.

• Fits Ford Edge (2007–2014), Explorer (2011–2023) with noted exceptions.
• Compatible with Flex, selective Fusion 3.5L V6, Taurus, Aviator, MKS, MKT, MKX, MKZ models listed by year.
• Also fits Mazda 6 3.7L V6 (2009–2013) and CX-9 (2007–2015), plus Mercury Sable (2008–2009).

Is installation difficult for a DIY person?

Installation is straightforward for anyone comfortable opening the airbox and swapping filters; the SPEARHEAD MT-242 matches OEM dimensions so no trimming or adapters are needed. Typical replacement takes only a few minutes with common hand tools or even just by hand in many vehicles.

• Direct OEM-style fit — no modification required.
• Simple airbox access on most compatible models; follow vehicle manual if unsure.
• Designed for easy inspection and replacement during routine maintenance.

Who is this for: The SPEARHEAD Max Thrust MT-242 is intended for owners of the listed Ford, Lincoln, Mazda and Mercury vehicles who want an OE-fit replacement with increased dirt-holding capacity. It suits drivers seeking an affordable, higher-capacity alternative to stock filters—especially those noticing reduced throttle response, poorer fuel economy, or who drive in dusty conditions and want a longer useful service interval.
