Intake Tube With Molded In MAF The best part of this Plastic JLT Big Air is we kicked the cool factor up a notch and molded a 123mm MAF housing right in the tube. This makes for a much smoother interior without any transitions, steps or couplers to upset the air flow. Another benefit is the over all look is just plain awesome! No Metal Tubing Here!!
