"The kit was easy to install and looks good. It gave the truck a nice throaty sound during acceleration. There is a noticeable increase in HP and MPG. Very happy with product. AutoAnything is excellent to business with." —Chuck J from Canton, GA bought a K&N 57 Series FIPK Air Intake (Fuel Injection Performance Kit) for a 2003 Nissan Frontier.
"Installation was a snap with the instructions. All I can say is it works. better throttler response, acceleration and a nice sound under a hard acceleration." —Robert G from Ashley, PA bought an AEM Brute Force Air Intakes for a 2003 Nissan Frontier.
"I read all the reviews on this site for the K&N intake on before ordering, and decided to experiment with it for myself as the price was right. As noted in the reviews, the instructions could be a bit more clear but the install took only about 1.5 hours (a 2nd set of hands is helpful). I've gone through 2 tanks of gas with the new intake so far & I saw a 2.8MPG (Highway driving)improvement on the 1st one and 1.5 MPG (city driving)on the second one. There is a noticeable improvement in power as I can cruise at the same speed but at 300 less RPM. It also adds a throatier exhaust note. Whine from the Supercharger is more evident now when I stomp the pedal but I don't mind. I would recommend this product & just ordered a Gibson Cat Back system to complement the intake!" —Bob K from Levittown, NY bought a K&N 57 Series FIPK Air Intake (Fuel Injection Performance Kit) for a 2003 Nissan Frontier.
"Does exactly as it is supposed to, I noticed a slight increase in my MPG and a little more pickup in the horsepower. Has a great "throaty" sound to it as well. The only issue I had was during installation, the hose connector they supplied didn't fit in the hole they provided in the intake without shaving or smashing the tip. Once we were able to force it in, the connector had some "play", but my mechanic friend said it wouldn't be a problem. Seems to be working fine after 2 weeks of driving (100 miles a day)." —Scott A from New Iberia, LA bought an AEM Brute Force Air Intakes for a 2003 Nissan Frontier.
"Don't go into this expecting miracles, the truck is still underpowered with the 3.3, even the supercharged model. That said, this intake really opened things up and added a noticeable increase in acceleration, particularly in the 3000 rpm range. Should mention the truck also has a Magnaflow cat-back exhaust, another necessary addition if you're wanting bolt-on power. Quality quite good, arrived in 3 days, looks nice, took an hour 1/2 to install. The white plastic vacuum takeoff fitting is wrong, chuck it and salvage the one off the original airbox. Can't wait to do these same mods to the wifes X-Terra." —Jon T from Cedar Hills, UT bought an AEM Brute Force Air Intakes for a 2003 Nissan Frontier.
"nissan frontier 2003 crew ext. bed 4wd. i was gettin about 270 miles out of a 16 gallon tank. after installation of this Kit it went to 311 miles per tank. increase in power, small but noticable, nice sound when air is inducted, happy to remove the crap air box and ridiculous tubes that were part of the stock air system.
