They come with K\u0026amp;N's Million Mile Limited Warranty™. These intake kits use only non-metallic rotationally molded tubes that can reduce air temperature and decrease intake sound over a metal tube. Restriction can exist BETWEEN an air filter and the engine reducing the benefit of a K\u0026amp;N Air Filter alone. The weakest link in the airflow chain robs a vehicle of its natural horsepower. Often that weak point is the factory air path leading to the engine. K\u0026amp;N Air Intake Kits virtually eliminate air path restriction by replacing the air filter and the entire air path to the engine. The aerodynamically engineered tube drives a massive amount of air into an engine, which translates into POWER. 57i Intakes are not legal for use in California and other US States adopting California emission standards.\u003c\/p\u003e Guaranteed to increase horsepower Designed to improve throttle response and engine sound Replaces entire factory air intake system Washable and reusable lifetime air filter K\u0026amp;N Million Mile Limited Warranty Lasts up to 100,000 miles before service is required (depending on driving conditions) | Easy to install, usually in 90 minutes or less","brand":"K\u0026N","offers":[{"title":"Default Title","offer_id":40394866163793,"sku":"KN57S-9503","price":364.99,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2115\/6365\/products\/57S-9503.jpg?v=1695132435","url":"https:\/\/longboostperformance.com\/products\/k-n-57s-9503-performance-air-intake-system","provider":"LongBoost Performance Parts","version":"1.0","type":"link"}
