Acuity Cold Air Intake Curl Control 12-15 Civic Si 9th Gen

Acuity Cold Air intake for the 2012-2015 Honda Civic Si (9th Gen) Curl Control

The Acuity cold air intake system (cai) for the 9th gen Honda Civic Si is one of the best looking intakes on the market. Using painstaking resaearch fine tuning and overall thought process that will literally blow your mind. If you are looking for ultimate quality, this intake is it. Not only is the the best intake out for the 2012 to 2015 Honda Civic, it performs the best, it looks the best and all around has the best install directions for a total win in every way. A lot of people complain products of today are cheap, thats because they generally are focused on a budget minded customer. With this product you have the opposite, quality was the main target and we can clearly say Acuity nailed it. This 3.5 inch intake requires flashpro and for good reason, the massive amount of air that flows through this intake to get you maximum gains from your K24z7 will need to be swapped to a map based tune since the stock maf wont be able to properly read it. Power gains will be in the 10-14 hp range. Sound will be explosive and dominating. Probably the best part of a Honda is its intake note and leading with a proper intake is #1 way to make easy power and to sound amazing.

Carbon fiber, purple and smooth bends with a high flow filter and proper routing to the coldest spot in the engine bay are just some of the spectactular reason to go with this intake system. If price is no object you have landed on the best. For just a little more than the competition you can have the best and we whole heartedly think its worth its higher price tag.

AN EXCEPTIONAL INTAKE SYSTEM, BUILT ON THE OEM 2.0 MINDSET:

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 supplied with all components required to convert from your OEM intake (or other intake system) including intake components, battery relocation tray, and other supporting components.

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.

TUNING AND PERFORMANCE

Because the CURL CONTROL's intake has a full 3.5" inside diameter, the air velocity is reduced compared to stock, and the factory tune will cause the vehicle to run dangerously 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 proven to work well with a full 3.5" intake.

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.

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.

A Note About Carbon Components: The two silicone couplers and carbon tube supplied in this kit are all hand-made, one at a time. Because of this, there can naturally be some variation from one component to another. While fitment is assured because all parts are made on identical molds, it is possible that silicone components will occasionally have cosmetic scuffs or carbon components will have the occasional internal bump or external nick etc. Acuity checks parts carefully before shipping to make sure that everything meets structural requirements and is of the best cosmetic quality ACUITY can offer. That said, please note that the 1-year warranty against manufacturer does not cover against minor cosmetic imperfections due to this handmade nature of the product.
