Ultra Long Tube Dual Air Intake

The Stillen Ultra Long Tube Dual Air Intake is engineered to significantly enhance the performance of your 2009-2020 Nissan 370Z. It boasts an integrated system of variable diameter tubing and steps to maximize air velocity, with internally polished tubes that minimize 'turns' between the filters and the throttle body. The design strategically places two large filters ahead of the radiator, ensuring they receive the coldest possible incoming air while remaining easy to service. The manufacturer claims this intake provides a dyno-proven gain of 17.5 Rear Wheel Horsepower (WHP) and 13 ft/lb (WTQ), translating to an estimated 20-22 horsepower gain at the flywheel, all on the stock ECU tune. It also offers potential improvements in fuel efficiency (MPG) due to increased airflow and filtration efficiency. Installation is described as simple enough for a driveway project. However, it's recommended to remove the front fascia clip and slightly enlarge the holes through the front core support for the easiest installation. While it's possible to install without removing the bumper, it makes the process more difficult. The kit includes detailed installation instructions. It fits both standard 370Z and 370Z Nismo models, though Nismo models require slight modification, and specific instructions for this are not included. The product is CARB Exempt with EO# D436-22 for 2009-2016 models.
