An aircraft mechanics view
Purchasing the 63 series I was more so going for increased fuel economy, although the thought of extra horsepower sounded good. To my pleasure I saw an increase in both. As with most cold air intake kits there is the byproduct of noise, to my amazement K&N did a great job with their new design and use of material to lower decibles, giving you that growl only when you want it. I reccomend this kit to anyone looking for an easy quality increase to your horsepower arsenal.
