Nearly 1.5 years in the making, the ACUITY CURL CONTROL Cold Air Intake system was designed and painstakingly refined to be the best performing cold air intake for the 9th Generation Civic Si. Perhaps just as important, it was designed with careful attention to how it integrates with the OEM chassis mounting points and electrical connections. It is built from superior materials and requires no cutting or extending of OEM wiring and no clutch system bleeding during installation. The kit is designed to be incredibly complete, meaning a very simple installation.

The CURL CONTROL intake is designed to reduce pumping losses and reduce negative Helmholtz resonance effects to provide improved power and more desirable torque and power curves. In both internal and independent testing, ACUITY found the CURL CONTROL intake to produce 5-10 peak horsepower over the leading 3.5" aluminum cold air intake systems and up to 5% more area under both the power and torque curves, meaning more usable power, especially when compared to the stock airbox. Additionally, the CURL CONTROL intake helps to improve low-end torque and reduce the torque dip seen in almost all other intakes in mid-range RPMs. The result is an intake that not only provides impressive results over the stock airbox, but also impressive improvements over competing 3.5" intakes.

Because the CURL CONTROL's intake has a full 3.5" inside diameter, the air velocity is reduced compared to stock, and the factory MAF calibration will cause the vehicle to run lean. For that reason, it's absolutely essential to use a tuning solution like Hondata, K-Tuner etc. to account for the increased airflow to the engine. If temporarily running the car on a base calibration, make sure that the calibration is at least proven to work well with a full 3.5" intake.

Important Note About Aftermarket Motor Mounts (PLEASE READ)
The CURL CONTROL battery tray has been confirmed to fit when used with OEM and Hasport motor mounts. The kit is not plug and play with Hasport mounts. A small amount of grinding on the Hasport chassis-side transmission mount will allow the battery tray to be mounted, but it is ultimately the end-user's decision whether or not to do this. This intake system's battery tray IS NOT compatible with Innovative brand motor mounts.

Important Note About Aftermarket Batteries (PLEASE READ)
The CURL CONTROL battery tray was designed for use with an original equipment sized battery. Larger batteries may create fitment issues.
