AEM Cold Air Intake System For Infiniti Q70 & M37 2011ƒ??2017 V6 3.7L F/I P/N 21-823DS

The AEM 21-823DS Cold Air Intake System is a dual intake setup engineered for select Infiniti Q70 and M37 models with a 3.7L V6 engine. This vehicle platform uses independent throttle bodies for each cylinder bank, so the system includes intake components for both the left and right sides. The kit replaces the factory air boxes, tubing, and filters with AEMƒ??s performance intake tubes, heat shields, and Dryflow synthetic air filters. Both sides utilize the factory mass airflow (MAF) sensors, which mount directly to the new intake tubes. The included heat shields feature rubber edge trim to help reduce heat soak by isolating the filters from engine bay temperatures. The filters are oil-free, washable, and designed for up to 100,000 miles between cleanings under normal driving conditions. Backed by AEMƒ??s Lifetime Limited Warranty. CARB status varies by applicationƒ??check specific listings for compliance.
