SPEARHEAD Engine Air Filter MT-295 — Fits 2017–23 Subaru, OEM Fit & High Dust Capacity

The SPEARHEAD Max Thrust Engine Air Filter (MT-295) is a direct-fit replacement filter engineered to trap more dust while maintaining strong airflow for compatible 2017–2023 Subaru engines.

If your vehicle has reduced throttle response, declining fuel economy, or simply has many miles on the clock, the air filter is an inexpensive maintenance item that often makes an immediate difference. The Max Thrust design uses a multi-layer Hex-D pleat structure and progressively finer media to increase contaminant capacity without choking airflow. It fits a range of Subaru models including Ascent, Forester, Crosstrek, Impreza, Legacy, Outback and WRX for the model years listed and is sold under part code MT-295.

How does this filter improve engine breathing and performance?

The Max Thrust focuses on holding more dirt while still allowing free airflow into the intake. Multiple layers of filter media capture larger particles first and finer particles deeper in the structure, which reduces resistance compared with a single-thickness element when loaded. Better airflow helps the engine draw air more efficiently under normal driving conditions.

• Hex-D pleat geometry increases surface area for filtration without adding bulk
• Layered media traps a wider range of particle sizes
• Engine-friendly airflow profile preserves throttle response

What is the expected service interval and dirt-holding capacity?

SPEARHEAD designs the Max Thrust to provide extended service life versus many standard disposable filters; depending on driving conditions it can function effectively up to 15,000 miles before replacement is recommended. The construction emphasizes increased dust-holding capacity so it reaches service life later while maintaining acceptable airflow for longer.

• Rated for use up to approximately 15K miles under normal driving
• Higher contaminant capture than basic OE-style paper elements
• Recommended inspection whenever other routine services are performed

Will this part fit my Subaru and is installation difficult?

MT-295 is manufactured for OEM-compatible fitment with specified Subaru models and model years—always confirm year, make and model before purchase. Installation is straightforward: the air box is easily accessible on these vehicles and the replacement is a basic do-it-yourself task that requires no special tools for most owners.

• Direct replacement for listed Ascent, Forester, Crosstrek, Impreza, Legacy, Outback and WRX years
• Simple swap—pop open the airbox, remove the old filter, insert the new one
• Saves a trip to the shop and reduces maintenance costs

How does this compare to the filter that came with my car?

Compared with many factory-supplied paper filters, the SPEARHEAD Max Thrust emphasizes greater contaminant capacity and a pleat structure that preserves airflow under load. It is engineered as an affordable upgrade rather than a high-restriction performance accessory—so you get improved longevity and cleaner intake air without altering factory engine calibration.

• Higher dirt-holding capacity than some standard OE filters
• Maintains free-flow characteristics to avoid performance penalties
• Designed for hassle-free OEM-style replacement

Who is this for: Drivers of compatible Subaru models who want an easy-to-install, OEM-fit replacement that captures more dust and debris while preserving intake airflow. It’s a practical choice for daily drivers, commuters, and higher-mileage vehicles where extending filter life and maintaining throttle response matter more than aftermarket power tuning.
