PRL Motorsports Short Ram Air Intake System - 17+ Civic Si 1.5TThe CNC machined billet aluminum MAF Housing was designed to provide *factory spec fuel trims ( 4% of factory STFT & LTFT) for optimal drivability and performance. 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. As mentioned above, the Street housing is designed to provide

The CNC machined billet aluminum MAF Housing was designed to provide *factory-spec fuel trims (-4% of factory STFT & LTFT) for optimal drivability and performance. 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. As 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.

Notes:

• NO CALIBRATION REQUIRED FOR STREET MAF HOUSING
• RACE MAF-SPECIFIC CALIBRATION IS REQUIRED FOR RACE MAF HOUSING
• RACE MAF BASEMAP CALIBRATIONS AVAILABLE IN BOTH HONDATA & KTUNER
• TWO STEP PERFORMANCE "TSP" & PHEARABLE CALIBRATIONS COMPATIBLE BY SELECTING "RACE MAF" OPTION
