Injen Cold Air Intake for 12-15 Civic Si/13-15 ILX 2.4L

Gains of Up to 16 hp/12 lb-ft of Torque Aggressive Engine Sound Compatible with 9th Gen Civic Si & 13-15 ILX Available in Polished or Black Finishes Description Vehicle Fitment Technical Data Included Install Guide Injen SP Cold Air Intake - 2012-2015 Honda Civic Si / 2013-2015 Acura ILX 2.4 Your 9th gen Civic Si or ILX 2.4's got a restrictive factory airbox that's choking the K24Z7. The stock intake uses a small paper filter in a cramped plastic housing that can't flow enough air when you're making power. You're losing horsepower because the engine can't pull the air it needs. Injen's SP Cold Air Intake replaces the entire factory airbox with a mandrel-bent 6061-T6 aluminum intake tube and an oversized SuperNano-Web dry filter that sits low in the fenderwell. You're getting cold air from outside the engine bay instead of hot air from around the engine. Injen dyno-tested this intake on a Civic Si and it made 16 hp and 12 lb-ft of torque over stock. That's real gains you're going to feel. The intake uses Injen's patented MR Technology and Air Fusion which are tuning processes that optimize airflow and maintain safe air/fuel ratios. No tune required. You're bolting this on and driving. The intake also sounds way more aggressive under throttle. You're hearing the engine pull air instead of the muffled wheeze the stock airbox makes. This intake's CARB legal with EO number D-476-8 for 2012-2013 models. It comes with a battery relocation kit because the filter sits where the battery used to be. The kit includes everything you need to move the battery and install the intake. Available in polished aluminum or wrinkle black finish. Made in California with Injen's lifetime warranty. Here's Why You're Getting 16 HP and 12 Lb-Ft Over Stock The stock Civic Si and ILX intake is designed to be quiet and to fit around other engine bay components. Honda didn't design it to make maximum power. The paper filter's small. The airbox is cramped. The intake tubing has bends and restrictions. When you're on the throttle the engine's starving for air. Injen's SP intake fixes that. The SuperNano-Web filter has way more surface area than the stock flat panel filter. More surface area means more airflow and better filtration. The filter sits low in the fenderwell where it's pulling cold air from outside the engine bay. Cold air's denser than hot air. Denser air means more oxygen which means more power. The 6061-T6 aluminum tube is mandrel-bent which means it's smooth on the inside with no crimping. The diameter's larger than the stock intake tubing. Larger diameter and smooth bends mean less restriction and better flow. Injen dyno-tested this intake on a stock Civic Si and validated the gains. 16 hp and 12 lb-ft of torque. Those are real repeatable numbers. You're feeling the difference in throttle response and acceleration. Injen's Patented MR Technology and Air Fusion Injen holds four patents on intake tuning technology. That's something no other intake manufacturer can claim. The SP intake uses Injen's patented MR Technology (MegaRam Technology, patents 7,359,795 and 7,669,571) and Air Fusion (patent 7,721,669). Here's what that means. MR Technology uses calculated tube diameter and length to optimize airflow velocity and pressure waves. The intake tube isn't just a random diameter pipe. It's engineered to create a ram-air effect that increases air density at the throttle body. Air Fusion is Injen's tuning process that maintains safe air/fuel ratios throughout the power band. Most intakes make power at the top end but run lean in the midrange. Injen's Air Fusion process ensures the intake maintains proper A/F ratios from idle to redline. That means you're making power safely without risking lean conditions that can damage your engine. No tune required. The intake works correctly with your factory ECU. Battery Relocation Kit Included - Filter Sits Where Battery Was The SP intake is a true cold air intake. The filter sits low in the driver's side fenderwell where the factory battery used to be. That's the coldest air location in the engine bay. You're pulling ambient air from outside the car instead of hot air from the engine bay. The intake includes a complete battery relocation kit. You're moving the battery to a new location (typically the trunk or a relocation tray) and the intake filter mounts where the battery was. The relocation kit includes all the necessary brackets, cables, and hardware. Some people don't want to deal with relocating the battery. If that's you, this isn't the right intake. If you want maximum power gains and you're willing to relocate the battery, this is the intake that makes the most power for a Civic Si or ILX 2.4. The battery relocation also frees up space in the engine bay which makes working on the car easier and looks cleaner. SuperNano-Web Dry Filter - Washable and Reusable The intake uses Injen's SuperNano-Web dry filter. It's a cone-style filter with way more surface area than the stock flat panel. The filter media is synthetic dry material. That means it doesn't use oil like K&N filters. Oiled filters can contaminate your MAF sensor if you over-oil them. Injen's dry filter eliminates that risk. The SuperNano-Web media traps dirt and contaminants while flowing more air than paper. When the filter gets dirty you wash it with soap and water, let it dry, and reinstall it. You're not buying replacement filters. You're cleaning and reusing the same filter. Injen also offers an optional hydroshield (part 1035BLK) which is a pre-filter cover that protects the filter from water if you're driving in heavy rain or through puddles. The replacement filter element is part number X-1017-BB if you ever need a new one. Most people never do because the filter lasts for the life of the car with proper cleaning. Polished or Wrinkle Black Finish - Made in California Injen offers this intake in two finishes. Polished aluminum (part SP1575P) for a shiny mirror finish that looks clean in the engine bay. Or wrinkle black powder coat (part SP1575BLK) for a stealthy murdered-out look. Both finishes are durable and corrosion-resistant. The intake tube is 6061-T6 aluminum which is lightweight and strong. All the hardware is stainless steel so nothing's going to rust or corrode. Injen manufactures these intakes in Pomona, California. They're not importing generic pipes from overseas and slapping a logo on them. They're designing, engineering, and manufacturing these intakes in the US. Every intake is backed by Injen's lifetime warranty. If something breaks or fails, Injen replaces it. That's how confident they are in their product.
