The BLITZ LM Intake System was design to reduce intake restriction and provide maximum filtration. The LM intake system was design to filter without any assistance of oil. (Oil can gradually disperse into the inlet tracks and coat walls of the air flow meter which can slowly reduce the performance of your vehicle.) The LM system was also design with a replaceable filter element. Unlike any other conventional one piece filter, the LM intake's filter element can be replaced at any time. The LM filter element comes in 3 colors, black, orange and blue.
