XDP offers many of the top intake system brands in the industry like AFE, S&B, Banks, AIRAID, K&N, and more! You can choose between an oiled or dry air filter for your air intake system. Both the oiled and dry filter are an upgrade over the factory air filter originally equipped on your vehicle. Aftermarket Air Intake Systems are engineered to eliminate the restrictive angles found in the OEM intake system and replace it with an improved design that results in increased airflow to your vehicles engine. Many aftermarket air intake systems feature underhood heat shields and enclosed air boxes. These innovative designs help to block warm underhood air and allow your engine to get the coldest, and most dense intake air.
