This mini filter is designed to catch the oil and moisture that could enter the intake tube from your engine, the air will no longer crank up into the intake airstream like a carbon filter. This air intake tube kit is an ideal choice for either the street or performance enthusiast looking to upgrade their air filter with a high quality cold air intake system by adding a high flow of cold air into your engine bay. This racing air cleaner will collect a lot of dirt from your intake system and will help the engine to draw more water into your engine so that it can be used as a carbon dioxide tank.
