They come with K\u0026amp;N's No-Hassle Lifetime 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.","brand":"K\u0026N","offers":[{"title":"Default Title","offer_id":62791786561617,"sku":"KN57I-2503","price":589.99,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2115\/6365\/files\/KN57I-2503-K-N-22006668165207.jpg?v=1790986913","url":"https:\/\/longboostperformance.com\/products\/57i-2503-k-n-performance-air-intake-system","provider":"LongBoost Performance Parts","version":"1.0","type":"link"}
