COBB Post MAF Hose Black 2002-2007 WRX / 2004-2007 STI

The 4-ply silicone construction has the right compliance to bridge the chassis mounted airbox to the violent motion of a boxer engine being driven in anger, while the steel reinforcement prevents collapse when the turbo is drawing maximum vacuum at wide open throttle.

COBB Post MAF Hose:

• Replaces corrugated OEM tube, smoothing airflow to the turbo
• 4 ply silicone with steel reinforcement construction
• Compliance absorbs relative motion between engine and chassis
• Steel reinforcement prevents collapse under maximum demand
• Choice of Stealth Black or COBB Blue
