Like the ID1300x and ID1700x, the ID1050x is not a modified production component.

JLT Cold Air Intake (Black Textured) only option

FIRST TO MARKET We put a ton of hard work into getting this intake done THIS EARLY and the results are nothing short of awesome. INTAKE TUBE WITH MOLDED IN MAF JLT's 2015 Cold Air Intake is better than ever. Fully computer designed to optimize space and for best fit and finish. Large 5" filter inlet with radiused end for smooth air flow across the MAF. MAF size is 110mm. Tube measures 4" at the throttle body side in preparation for larger after market throttle bodies. HEAT SHIELD Fully Roto molded heat shield and included fresh air duct to the grille designed to keep inlet air temps as cool as possible. AIR FILTER We use only the best air filters made by S&B to our specifications. We love S&B's tapered flange design and Powerstack filtered ends. With a huge 5” opening on the tube we needed a huge filter. The result is a monster 5x8” filter with built in screen to straighten airflow. TUNING A JLT specific tune is required with this kit. FINISH OPTIONS Standard finish is an OEM looking black textured plastic and also available in your cars exact body color. All painted tubes receive a special treatment so paint adheres correctly to the plastic and go through an in-depth process to remove all the texture. We then use only the best quality materials to give each tube a smooth gloss finish.
