K&N – Cold Air Intake: Guaranteed To Increase Horsepower, With Million Mile Air Filter (Part No.57I-1001)

Cold Air Intake: Guaranteed To Increase Horsepower, With Million Mile Air Filter

from

$399.99
K&N 57i Generation II Induction Kits are built primarily for European vehicles. 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&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&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.

Product Features:
  • GUARANTEED INCREASE IN HORSEPOWER: Dyno-tested with up to 50% more airflow than restrictive factory box air filter and intake tube
  • BETTER TOWING: Improves acceleration and uphill performance when towing by improving throttle response.
  • IMPROVED ENGINE SOUND: Hear the power under the hood.
  • WORLD CLASS PROTECTION: Pushing the limits of engine protection by protecting your engine from harmful contaminants
  • EASY MAINTENANCE: No filter cleaning required for up to 100,000 miles
  • EASY TO INSTALL: Bolt-on power in less than an hour with basic hand tools. K&N air intake systems are one of the easiest ways to guarantee an increase in horsepower.
  • DYNO TESTED: Dyno-tested for a guaranteed increase in horsepower and acceleration with no ECU tune required
  • HIGH QUALITY: Made in America.
