Our CNC machined billet aluminum MAF Housing was designed to provide *factory-spec fuel trims (-4% of factory STFT \u0026amp; LTFT) for optimal drivability and performance. The Cobra CAI utilizes a 4\" volume from the air filter into the MAF Housing and is available with two different MAF housing choices; a Standard Bore housing and a Big Bore housing. Both housings utilizes the factory MAF sensor, but feature two different diameters and profiles. As mentioned above, the Standard Bore housing is designed to provide factory-spec fuel trims WITHOUT any tuning whatsoever. The Big Bore housing allows a 50% larger volume of air in comparison to the Standard Bore housing, which is why a tune IS required. This larger volume of airflow reduces pumping loss and creates an unrestricted air path to feed the MAF housing with ambient temperature air.\u003c\/p\u003e\n\u003cp\u003eCustomers can switch between MAF housings without having to buy another intake system by purchasing our \u003ca href=\"https:\/\/prlmotorsports.myshopify.com\/collections\/intake\/products\/2016-honda-civic-1-5t-maf-housing-conversion-kit\"\u003eMAF Housing Conversion Kit\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003eCustomers can convert to a Short Ram Intake with our \u003ca href=\"https:\/\/prlmotorsports.myshopify.com\/collections\/intake\/products\/2016-honda-civic-1-5t-cold-air-intake-to-short-ram-conversion-kit\"\u003eShort Ram Intake Conversion Kit\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003ePerformance Gains:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e15 horsepower and 12 ft\/lb torque gains in comparison to stock with Standard Bore MAF housing WITHOUT TUNE - \u003ca href=\"http:\/\/prlarmy.com\/Blog\/project-snow-white-10th-gen-si-part-2-cobra-intake\/\"\u003eRead More Here\u003c\/a\u003e!\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eLarger gains to be seen at higher power levels with custom tuning\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cdiv\u003e\u003ciframe src=\"https:\/\/www.youtube.com\/embed\/9jvDEnRSI84\" height=\"315\" width=\"560\"\u003e\u003c\/iframe\u003e\u003c\/div\u003e\n\u003ch3\u003e\u003cbr\u003e\u003c\/h3\u003e\n\u003ch3\u003eThird Party Testing:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"http:\/\/prlarmy.com\/Blog\/hondata-tests-prl-intake-performance-gains-cobra\/\"\u003eHondata\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"http:\/\/prlarmy.com\/Blog\/innovative-motorworks-1-5t-intake-testing\/\"\u003eInnovative MotorWorks\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eKit Includes:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003eStandard Bore Cobra MAF Housing (Si)\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003ePRL Motorsports High Flow Oiled Cone Air Filter\u003c\/li\u003e\n\u003cli\u003e(1) 4-Ply Upper Silicone Intake Hose (Big Bore or Standard Bore)\u003c\/li\u003e\n\u003cli\u003e(1) 6-Ply Lower Silicone Intake Hose\u003c\/li\u003e\n\u003cli\u003eHDPE Rotomolded Lower Intake Tube\u003c\/li\u003e\n\u003cli\u003e(4) 304 Stainless Steel Worm Clamps\u003c\/li\u003e\n\u003cli\u003eStainless Steel Mounting Brackets\u003c\/li\u003e\n\u003cli\u003eStainless Steel Hardware\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003eSILICONE IS ONLY AVAILABLE IN BLACK – UPPER HOSE IS DIFFERENT THAN OUR “STAGE 1” SILICONE\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003ca href=\"https:\/\/s280.photobucket.com\/user\/prlspencer\/media\/Civic%20x%20L.trim%20stock%20intake%20and%20stock%20tune_zpsf1d7zfq3.jpg.html\" target=\"_blank\"\u003e\u003cimg alt=\"photo Civic x L.trim stock intake and stock tune_zpsf1d7zfq3.jpg\" border=\"0\" src=\"https:\/\/i280.photobucket.com\/albums\/kk200\/prlspencer\/Civic%20x%20L.trim%20stock%20intake%20and%20stock%20tune_zpsf1d7zfq3.jpg\"\u003e\u003c\/a\u003e\u003cbr\u003eAbove is a graph of the long term fuel trims with the stock intake w\/ air box and factory ECU mapping, or in other words a bone-stock car.\u003cbr\u003e\u003cbr\u003e\u003cimg alt=\"photo Civic x L.trim PRL intake and stock tune_zpscgiprogu.jpg\" border=\"0\" src=\"https:\/\/i280.photobucket.com\/albums\/kk200\/prlspencer\/Civic%20x%20L.trim%20PRL%20intake%20and%20stock%20tune_zpscgiprogu.jpg\"\u003e\u003cbr\u003eHere is a graph of the long term fuel trims again with, but with our cold air intake (Standard Bore MAF) and factory ECU mapping.\u003cbr\u003e\u003cbr\u003e\u003cimg alt=\"photo Civic x L.trim PRL intake and Hondata 6psi tune_zpssf6dz8bb.jpg\" border=\"0\" src=\"https:\/\/i280.photobucket.com\/albums\/kk200\/prlspencer\/Civic%20x%20L.trim%20PRL%20intake%20and%20Hondata%206psi%20tune_zpssf6dz8bb.jpg\"\u003e\u003cbr\u003eThis is another long term fuel trim graph, but with our cold air intake (Standard Bore MAF) and +6psi Hondata off-the-shelf map.\u003cbr\u003e\u003cbr\u003eNotice how consistent and similar all of the LTFT graphs are.
