EXPERIENCE AN OBVIOUS DIFFERENCE – Whether you are noticing a delay in acceleration, less than average gas mileage or own a higher mileage vehicle, our Max Thrust engine air filters will provide a clear & cost effective upgrade over stock performance – or your money back. | TRAP 2X THE DIRT VS. STANDARD AIR FILTERS – Our unique HeX-D pleat design creates maximum holding capacity for trapping unwanted dirt & debris without compromising airflow like standard air filters – thanks to multiple layers of progressively finer filter media that allows air to flow freely even when the filter is dirty. | INCREASED POWER & MILEAGE UP TO 15K MILES – Deficient airflow can cause your engine to work twice as hard to suck in the minimum amount of air it needs to perform regularly, resulting in poorer gas mileage and lower power efficiency. Max Thrust air filters are designed to give your engine a break by delivering as much clean air as it needs to perform optimally – up to 15K miles. | DIY W/GUARANTEED FITMENT – Replacement for Mazda 3 (2014-19) - SKYACTIV ONLY 2.0L L4 W/ENGINE VIN: 7,8,P (2013), Mazda 3 - 2.0L L4 ENGINE ONLY W/ENGINE VIN: 7,8,G (2012), Mazda 6 - 2.5L L4 ONLY (2018-19), Mazda 6 (2014-17), CX-5 - 2.5L NATURALLY ASPIRATED L4 GAS ONLY / DOES NOT FIT 'SIGNATURE', 'GRAND TOURING RESERVE', & 2.2L L4 DIESEL TRIMS (2019), CX-5 (2013-18).
