Most intakes skew the MAF reading, which means your ECU meters fuel from bad data and you get codes or poor running. PRL's CNC machined billet housing presents air to the factory sensor in a way it reads correctly at higher flow.\u003c\/p\u003e\n\n\u003cp\u003eOn an Si, that's 15 horsepower and 12 lb-ft over stock with no tune, no codes, and nothing to recalibrate. If your car is otherwise stock or you'd rather not tune, this is the version.\u003c\/p\u003e\n\n\u003ch4\u003eBig Bore: More Air, Needs A Calibration\u003c\/h4\u003e\n\n\u003cp\u003eThe Big Bore housing flows 50% more volume than the Standard Bore, which reduces pumping loss and gives the turbo a genuinely unrestricted path.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eA Big Bore specific calibration is required.\u003c\/strong\u003e Not optional. The housing flows too differently for the factory MAF scaling to work.\u003c\/p\u003e\n\n\u003cp\u003eThe good news is that basemaps exist for both \u003cstrong\u003eHondata and KTuner\u003c\/strong\u003e, so this isn't custom tuning work. Load the Big Bore basemap and you're running correctly. With that calibration on an Si, PRL measures 20 horsepower and 15 lb-ft over stock.\u003c\/p\u003e\n\n\u003cp\u003eRunning Two Step Performance or Phearable calibrations? Select the \u003cstrong\u003eRace MAF\u003c\/strong\u003e option, which is compatible with both.\u003c\/p\u003e\n\n\u003ch4\u003eThe Sound Is Half The Reason\u003c\/h4\u003e\n\n\u003cp\u003eBeing straight about why people actually buy this one.\u003c\/p\u003e\n\n\u003cp\u003eThe factory airbox on a 10th gen is sealed and quiet by design. Honda spent effort making a turbocharged engine sound like a naturally aspirated one, which is fine for a rental car and disappointing on an Si.\u003c\/p\u003e\n\n\u003cp\u003eThe Cobra puts the filter in open air, and what comes with that is everything the airbox was hiding. Induction noise under load, audible spool, and the distinct whoosh when you lift off throttle. It's the closest thing to a blow-off sound you'll get on a car with a factory recirculating valve.\u003c\/p\u003e\n\n\u003cp\u003eIf that's what you're after, this is the intake. If you'd rather keep things quiet, a sealed airbox design is the better fit.\u003c\/p\u003e\n\n\u003ch4\u003eTwo Things That Exclude Your Car\u003c\/h4\u003e\n\n\u003cp\u003eCheck both before ordering.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCanadian models\u003c\/strong\u003e need a USDM windshield washer reservoir conversion, which we don't stock. The Canadian reservoir sits where the intake wants to go, so that swap has to happen first and you'll need to source it separately.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eFactory CVT cooler cars are not compatible.\u003c\/strong\u003e That's primarily Spain, Turkey, and other international markets.
