The K&N 57-0656 is a 57i Series high-flow induction kit designed exclusively for the 2006-2008 Mazda MX-5 Miata 2.0L. It replaces the restrictive factory airbox with an oversized open-element air filter and mandrel-bent aluminum tubing for dyno-proven gains of 11.75 HP at 6301 RPM plus sharper throttle response and aggressive engine sound. This bolt-on system directs cooler denser air into the engine for power throughout the RPM range.
Key Features
- High-Flow Washable Air Filter: Captures more airflow with larger surface area than stock lasts up to 100000 miles before cleaning depending on conditions.
- Horsepower Gains: Dyno-tested 11.75 HP increase at 6301 RPM improves acceleration and overall performance.
- Mandrel-Bent Aluminum Tube: Smooth uninterrupted airflow with heat-resistant powder-coated finish for durability.
- Ships in protective box 20.25 x 12.5 x 9.25 inches weighing 5.25 lbs.
- Bolt-on design completes in 90 minutes or less using basic hand tools.
- Adapts directly to throttle body with included steel and aluminum components no cutting or drilling needed.
