Their 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\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eNO CALIBRATION REQUIRED FOR SANDARD BORE MAF HOUSING\u003c\/li\u003e\n\u003cli\u003eBIG BORE MAF-SPECIFIC CALIBRATION IS REQUIRED FOR BIG BORE MAF HOUSING\u003c\/li\u003e\n\u003cli\u003eBIG BORE MAF BASEMAP CALIBRATIONS AVAILABLE IN BOTH HONDATA \u0026amp; KTUNER\u003c\/li\u003e\n\u003cli\u003eTWO STEP PERFORMANCE \"TSP\" \u0026amp; PHEARABLE CALIBRATIONS COMPATIBLE BY SELECTING \"RACE MAF\" OPTION\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"PRL","offers":[{"title":"Standard Bore MAF Housing","offer_id":44492621775100,"sku":"HC10INTCAIB","price":499.0,"currency_code":"CAD","in_stock":false},{"title":"Big Bore MAF Housing","offer_id":44492621807868,"sku":"HC10INTCAID","price":499.0,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2571\/0092\/files\/2017-2021-honda-civic-si-15t-cobra-cold-air-intake-system-627205_600x_b5bec52f-334c-471a-a3a8-952f41b2ba24.jpg?v=1690480510","url":"https:\/\/perryautolaval.com\/products\/prl-cold-air-intake-for-17-21-honda-civic-si","provider":"Perry Performance \u0026 Competition","version":"1.0","type":"link"}
