"The cold air intake system was very easy to install. The instructions were very detailed and the pictures were excellent in pointing out areas of interest when installing the system. After having it installed now for approximately 3 weeks, I have been able to see about a 3 to 4 mile per gallon increase in fuel mileage. Which, in an age of $3.50 gas, any little bit helps. Also, upon my initial test drive immediately after the install, I was able to tell a nice boost in HP that was very noticable in the 3000 to 4500 RPM range. The car is also a little bit louder than stock but it is a nice "throaty" sounds now over the stock system and is not by any means annoying. Overall I would highly recommend this product not only for the ease of install and price, but also for the added benefits you receive in the form of increased gas mileage and more HP. You will not be disappointed." —Tyler Y from New Hampton, IA bought a K&N 57 Series FIPK Air Intake (Fuel Injection Performance Kit) for a 2003 Chevy Impala, 3.8L V6.
