xUpgrade your engine breathing with Spearhead Max Thrust
Your engine relies on a steady, clean flow of air to perform reliably. The Spearhead Max Thrust Engine Air Filter Replacement (MT-259) is engineered to fit select Mazda models and to deliver a consistent supply of clean air to the intake. Compatible with Mazda 6 from 2012 to 2023, Mazda 3 Skyactiv variants, and CX-5 equipped with naturally aspirated 2.0L or 2.5L engines, this filter aims to support smoother response and steady operating behavior across varied driving conditions.
Design and filtration play a crucial role in everyday driving. The Max Thrust filter uses a Hex-D pleat design that increases dirt holding capacity, helping to trap more particles before they can impact airflow. Add in multiple layers of progressively finer filter media, and air is guided through a path that minimizes restrictions even as the filter collects dust. The result is a filtration system built to maintain steady intake performance rather than dropping off as debris builds up.
Performance and durability are at the core of this replacement. By delivering clean air the engine needs, the Max Thrust design can support consistent power delivery and efficiency across typical daily driving and longer trips. With an optimized balance of filtration and airflow, the filter is designed for use up to 15,000 miles in typical conditions, offering a practical alternative to more frequent replacements when stock filters begin to restrict airflow.
DIY friendly with broad compatibility, this replacement is intended for easier at-home service. The filter is designed to fit a range of Mazda models with 2.0L and 2.5L naturally aspirated engines, including Mazda 3 and Mazda 6 as well as CX-5 variants. Specific compatibility includes Mazda 3 (2012–2018) and Skyactiv 2.0L variants, Mazda 6 (2014–2021) with 2.5L NA, and CX-5 (2013–2018 and later NA 2.5L). Some turbocharged engines or certain trims may require a different part number, so it’s wise to verify fit with your vehicle’s VIN or OEM specifications before installation.
Key advantages
- Higher dirt holding capacity thanks to the Hex-D pleat design

In short, the Max Thrust filter presents a practical upgrade path over typical stock filters by emphasizing cleaner air, easier maintenance, and compatibility across a broad Mazda lineup. While results can vary with driving conditions, many users find this design offers a sensible balance of performance potential and value.
