Description
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.
Air Handling
With its hand-laid carbon fiber and bonded billet 6061 aluminum appointments, this intake's carbon tube is the centerpiece in both performance and appearance. Air enters through a large, 6" dry filter, mounted to a spun aluminum velocity stack that reduces to 3.5". The silicone couplers located on either end of the carbon tube are designed with reliefs to provide a smoother transition as air enters and exits the intake. The throttle body coupler features an integral aluminum hose barb. Silicone hoses are also provided for the valve cover breather and coolant bypass. The carbon tube features a bonded billet 6061 aluminum MAF mount and mounting boss, both anodized in ACUITY's signature purple. Also supplied with the kit are German-style hose clamps. While more difficult to tighten compared to traditional clamps, German-style clamps provide more even clamping and have formed threads and rolled edges to prevent damage to the silicone couplers.
Battery and Wire Management
The supplied battery tray is both attractive and durable. This is thanks in part to the careful combination of stainless steel and aluminum, allowing it to be strong where it must and light where it can, all while providing a rust-resistant design that will age gracefully. With laser-etched wire routing callouts and integral mount points for the battery ground and all wiring extensions, the battery tray ties the CURL CONTROL kit together to make it the most well-integrated 9th Gen Civic Cold Air Intake kit available. No wire cutting or splicing is needed. Instead, wire extensions are supplied to allow plug and play installation.
Upgrades Made Easy
With the variety of intake manifolds and throttle bodies available to 9th Gen Civic Si owners, we know that there are good odds you'll want to change one or both of those components down the line. We're here to make those mods easier. ACUITY sells the throttle body couplers for each kit separately so that if you ever change your manifold or throttle body, you can simply buy a coupler and upgrade your original CURL CONTROL kit.
