More power, maybe a bigger turbo on the way, and your tuner is watching the MAF signal climb toward its ceiling at the top of every pull. The 89mm Race housing swaps in where the 76mm sits and gives that same factory sensor the room to keep reading airflow as the power rises. It lets your intake grow with the rest of the car.\u003c\/p\u003e\n\n\u003ch3\u003eRead this first: it's a housing, not a whole intake\u003c\/h3\u003e\n\n\u003cp\u003eThis page covers the 89mm Race MAF housing and its matched velocity stack only, the upgrade piece for a Formula Intake you already own. If you don't have the Formula Intake yet, this won't run on its own, so order the full intake instead. What you're buying here converts your existing setup from Street to Race spec.\u003c\/p\u003e\n\n\u003ch3\u003eWhen you actually need it\u003c\/h3\u003e\n\n\u003cp\u003eThe 89mm isn't a more-is-better part. The factory MAF sensor reads airflow as a voltage, and it tops out around 5.0 volts. On the 76mm Street housing, a high-power FK8 will push that signal into the ceiling, and once the sensor stops climbing, your tuner loses sight of airflow at the top of the pull. The wider 89mm housing slows the air across that same sensor, so the voltage stays inside its usable range and the tune stays accurate.\u003c\/p\u003e\n\n\u003cp\u003eHybrid Racing saw this on their shop car. At 433.5 wheel horsepower, the 76mm Street signal hit 4.96 volts and quit climbing near redline. The 89mm Race kept that same sensor in range. A good rule: around 400 wheel horsepower, have your tuner start watching MAF voltage, and let the datalog make the call rather than the dyno number. If your FK8 is stock or lightly modified, you don't need this yet. The 89mm gives more sensor range than that car can use, so there's nothing to gain by jumping to it early.\u003c\/p\u003e\n\n\u003ch3\u003eThis one requires a tune\u003c\/h3\u003e\n\n\u003cp\u003eThe 76mm Street bolts on and drives. The 89mm Race doesn't. It needs \u003ca href=\"https:\/\/www.hybrid-racing.com\/products\/hondata-flashpro-2017-civic-type-r?_pos=3\u0026amp;_sid=2f40cf6f9\u0026amp;_ss=r\"\u003eHondata FlashPro\u003c\/a\u003e or an equivalent tuning solution that can apply the matching MAF calibration, because the ECU has to be told how to read the new housing. There's no complimentary basemap for the Race housing, and that's deliberate. Cars that need the 89mm carry their own mix of supporting mods, and no single file could cover every combination safely. Plan on custom tuning. If you want help finding the right calibration or a tuner who knows these cars, ask us and we'll point you in the right direction.\u003c\/p\u003e\n\n\u003ch3\u003eThe swap is simple\u003c\/h3\u003e\n\n\u003cp\u003eAlmost everything carries over. You keep the same XLPE airbox, the same red filter, the same outside-air feeds, the same coupler, and the same factory Honda MAF sensor. Only the housing and its matched velocity stack change. Pull the 76mm housing, fit the 89mm and its stack, move the sensor across, and get the car retuned for the new path. Going back later is the same job in reverse.\u003c\/p\u003e\n\n\u003ch3\u003eBuilt and proven\u003c\/h3\u003e\n\n\u003cp\u003eHybrid Racing didn't arrive at this casually. The Formula Intake came out of flow-bench work, sixteen material and shielding samples, and sixty-five dyno pulls before anything got signed off. The 89mm Race housing is the high-power end of that same testing, built so your sensor keeps measuring and your tuner keeps control once the build gets serious. Reach for it once you've outgrown the Street housing.\u003c\/p\u003e\n\n\u003ch3\u003eWho this is for\u003c\/h3\u003e\n\n\u003cp\u003eThis is for the FK8 owner already deep in a build. You run the Formula Intake, you're making real power, and your datalogs show the 76mm running out of sensor range, or you're setting up for a bigger turbo and want the headroom in place before you get there. Swap it in, get it calibrated, and keep building.\u003c\/p\u003e\n\n\u003ch3\u003eAt a glance\u003c\/h3\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e All 2017-2021 Honda Civic Type R (FK8), including the 2021 Limited Edition\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRequires:\u003c\/strong\u003e An existing Hybrid Racing Formula Intake, plus \u003ca href=\"https:\/\/www.hybrid-racing.com\/products\/hondata-flashpro-2017-civic-type-r?_pos=3\u0026amp;_sid=2f40cf6f9\u0026amp;_ss=r\"\u003eHondata FlashPro\u003c\/a\u003e or an equivalent tuning solution\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e 89mm Race MAF housing and matched velocity stack\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReuses:\u003c\/strong\u003e Your existing Hybrid Racing airbox, filter, outside-air feeds, coupler, and factory Honda MAF sensor\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNote:\u003c\/strong\u003e No complimentary basemap, custom tuning required\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBest for:\u003c\/strong\u003e Builds approaching the factory MAF sensor's 5.0-volt limit, or planning a larger turbo\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Torque GT","offers":[{"title":"Default Title","offer_id":58784400769349,"sku":"HYB-CAI-01-27","price":106.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0895\/2014\/4709\/files\/HYB-CAI-01-27_v307.webp?v=1786010786","url":"https:\/\/torque-gt.co.uk\/es\/products\/hybrid-racing-formula-intake-tube-upgrade-civic-type-r-fk8","provider":"Torque GT","version":"1.0","type":"link"}
