{"product_id":"8th-gen-civic-si-cold-air-intake-system-1","title":"8th Gen Civic Si Cold Air Intake System","description":"The Hybrid Racing Cold Air Intake System is engineered for the 8th Gen Civic Si platform, from stock to high-lift cams and large exhausts. This system boasts a full silicone construction with 1\/4\" thick fiberglass-reinforced tubing, which insulates the intake charge more effectively than metal or plastic, leading to colder intake air temperatures, a denser air charge, and increased overall power.\n\nA key component is the 6\" velocity stack, designed to reduce inlet restrictions and allow more air into the engine. The kit also includes an injection-molded air bypass manifold that integrates attachment points for the factory MAF, valve cover vent, and air bypass valve. This manifold features a built-in air bypass function to prevent hydro-locking if the intake filter becomes wet, as demonstrated in testing where the engine idled and revved safely even with a submerged filter. The internal geometry of the bypass manifold also works to reduce parasitic Helmholtz resonance, smoothing the power band.\n\nThis intake system is credited with making up to 14hp over the stock air box and 2-3hp more than other 3.5\" cold air intakes, while offering a smoother power band. It includes a powder-coated steel battery tray to relocate the battery, providing clearance for the larger piping. A silicone upper radiator hose is also included for improved clearance, along with silicone tubing to replace the OEM valve cover breather and air bypass tube for a cleaner appearance. All necessary hardware for installation is provided.\n\nPlease note that this intake system requires tuning software such as FlashPro. It is designed for the 2006-2011 Honda Civic Si (FA5\/FG2) and may require modification for the 2007-2010 Civic Type R FD2\/FN2. The kit comes with couplers for both large and small throttle bodies, a 3.5\" velocity stack and filter, and a battery relocation kit.","brand":"Hybrid","offers":[{"title":"Default Title","offer_id":52688772628792,"sku":"HYB-CAI-01-10","price":370.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/663182989.webp?v=1784895413","url":"https:\/\/store.motormia.co\/products\/8th-gen-civic-si-cold-air-intake-system-1","provider":"MOTORMIA","version":"1.0","type":"link"}
