This SRI utilizes a 4\" air filter and is available with two different MAF housing choices; a Street housing and a Race housing. Both housings utilizes the factory MAF sensor, but feature two different diameters and profiles.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eAs mentioned above, the Street housing is designed to provide factory-spec fuel trims WITHOUT any tuning whatsoever. The Race housing allows a 50% larger volume of air in comparison to the Street 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\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCNC machined billet aluminum MAF Housing\u003c\/li\u003e\n\u003cli\u003eUtilizes a 4\" performance air filter\u003c\/li\u003e\n\u003cli\u003eAvailable with two MAF housing choices; a Street housing and a Race housing\u003c\/li\u003e\n\u003cli\u003eStreet housing is designed to provide factory-spec fuel trims (-4% of factory STFT \u0026amp; LTFT) WITHOUT any tuning whatsoever\u003c\/li\u003e\n\u003cli\u003eRace housing allows a 50% larger volume of air in comparison to the Street housing and requires a tune.
