Overview

Important Notes

• NO ECU CALBIRATION REQUIRED FOR STANDARD BORE MAF HOUSING
• BIG BORE MAF-SPECIFIC ECU CALIBRATION REQUIRED FOR BIG BORE MAF HOUSING
• HONDATA & KTUNER BOTH OFFER BIG BORE MAF BASEMAP CALIBRATIONS
• TWO STEP PERFORMANCE "TSP" TUNE(S) & PHEARABLE TUNE(S) COMPATIBLE BY SELECTING "RACE MAF" OPTION

Technical Notes:

Our 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 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.

Customers can switch between MAF housings without having to buy another intake system by purchasing our MAF Housing Conversion Kit

Performance Gains:

• 15 horsepower and 12 ft/lb torque gains in comparison to stock with Standard Bore MAF housing WITHOUT TUNE
• 20 horsepower and 15 ft/lb torque gains in comparison to stock with Big Bore MAF housing WITH Big Bore MAF basemap calibration on Hondata and/or KTuner
• Larger gains to be seen at higher power levels with custom tuning
