The AIRAID MXP Air Intake System is the pinnacle of cold air induction for high-performance gas and diesel vehicles. Engineered to overcome factory intake limitations, it features a one-piece, roto-molded air box that improves airflow while housing a premium AIRAID air filter. Choose the filter that best suits your needs:

• Non-Oiled (SynthaMax): Washable and reusable synthetic media, perfect for easy maintenance without the use of oils.
• Oiled: Traditional oiled cotton gauze for maximum airflow and superior dust-trapping performance.
• Oiled (SynthaMax Black or Blue): Oiled synthetic media offering a stylish touch with reliable filtration and airflow.

A cross-linked, high-density polyethylene intake tube—shaped through extensive CAD modeling—ensures accurate MAF readings and optimized air delivery. Many MXP systems also feature a built-in velocity stack to further smooth and accelerate airflow into the engine.
