This kit includes everything you need to convert / upgrade the MAF housing portion of your PRL FK8 Civic Type R High Volume Intake (HVI).

• Includes CNC machined billet aluminum MAF housing, silicone hose, worm clamps, and EVAP fitting.
• CNC machined billet aluminum MAF housing provides factory-spec fuel trims (-4% of factory STFT & LTFT) for optimal driveability and performance.
