"I've owned other K&N cold air intakes on 4, 6, and 8 cylinder engines, but I didn't notice much of a difference from the stock air intake...that was running a K&N replacement filter prior to installation of the cold air intake. No real noticeable change for the 350z with this product. I've always used K&N products on all of my vehicles. However, on this particular car...not much performance or fuel economy difference. Wish it were otherwise. That's the reasoning behind my price/value rating." —James D from Sterlington, LA bought a K&N 57 Series FIPK Air Intake (Fuel Injection Performance Kit) for a 2003 Nissan 350Z.
"Good product overall.Took me about 45 min to install start to finish. Directions from AEM are good with pics to help. It looks great under the hood and sounds awesome once you get up to the 4K RPM level with the engine. This is my first mod on my Z, the performace and sound was noticeable. A little quicker throttle response in the mid-range and top-end of the RPM band." —Chris N from Revere, MA bought an AEM Cold Air Intake System for a 2003 Nissan 350Z.
"sounds great, added a bit of hp and torque, looks great as well" —Naithan S from Abilene, TX bought an AEM Cold Air Intake System for a 2003 Nissan 350Z.
"This intake definitely made my car have a deeper growl to it and i love the way it does its whistling sound when i rev it while driving or parked. I can also feel the difference in its acceleration and i love how at high speeds, the sounds it makes just gets deeper and louder" —Justin N from Round Lake Beach, IL bought an aFe Cold Air Intakes for a 2003 Nissan 350Z.
"Already had an aftermarket intake so it wasnt too much of an improvement horsepower wise, however i did notice a slight difference. Mpg increased about 2 or 3 and it sounds slightly more aggresive. It is definitely wirth it for people with stock intake systems and it will help one in the long run" —Juan G from Bloomington, CA bought a K&N 69 Series Typhoon Intake Systems for a 2003 Nissan 350Z.
"Really liked the product. Noticed an increase in performance immediately. The installation was a little more involved on the 2008 hummer h3 than I expected. I had to drill a hole in the firewall. But the instructions stated that once I recieved the filter. All necessary installation materials were included. I would definately recomend this product." —Gerald David C from Savannah, GA bought a K&N 63 Series AirCharger High-Flow Intake Kit for a 2003 Nissan 350Z.
