K&N Air Intake Systems for Infiniti

We feel a high quality performance intake system is one of the best dollars to horsepower investments you can make and once again K&N is the clearly defined leader when it comes to cold air intakes. 

BOLT-ON HORSEPOWER GUARANTEED! K&N Performance Air Intake systems are built for horsepower. If K&N can’t increase a car or truck's horsepower K&N won’t build a cold air intake for it. It’s that simple. K&N establishes a stock baseline horsepower with their in house dynamometers and then designs K&N air intakes to get the largest horsepower gain attainable without causing a “Check Engine Light” to come on. K&N horsepower numbers are not based on the single biggest gain from one particular vehicle but are an average of runs and vehicles. Many times an identical vehicle will perform differently so K&N wants to ensure repeatable numbers you can count on. In today’s market place there are some pretty big cold air intake claims. K&N doesn't make claims; they present the facts, backed up by well documented tests. 

K&N invented the world’s first air filter guaranteed for one million miles. That same warranty applies to K&N High-Flow Air Intake Systems. K&N products are well engineered, built with the finest materials and K&N stands behind them 100% Buy a K&N Cold Air Intake today. You be glad you did.
