5 reasons why you should install a cold air intake: Less restriction:The easier it is for your engine to get air & fuel the more efficient it will run and the more potential power you can create. This can also lead to better mpg if all other factors involved are in working order. Less Maintenance:Many air filters require less cleaning/replacement. Replacement filters in a factory air box usually last about 50,000 miles before needing a cleaning and the large conical filters on the end of an intake system usually last 100,000 miles before needing a cleaning. Doesn’t void your warranty:Thanks to the Magnuson-Moss Warranty Act, it’s against United States federal law to require the use of a specific brand of air or oil filter unless it provides a replacement air or oil filter, free of charge, under the terms of the vehicle warranty. DIY Install:Not many performance modifications are as easy to install with common household tools as a CAI. You will be up and running in minutes! Appearance: We would all be lying if we said we didn’t like things to look cool. A big conical air filter or intake tube looks as cool as they sound and perform. When you are popping your hood at a car show you better have a clean intake.
