Air Flow Tubes (Automotive)

KOK designs and manufactures air flow tubes for OEM automotive air intake systems, engineered to maintain stable airflow and dimensional integrity between the air filter housing, mass air flow sensor, and throttle body.

KOK air flow tubes are developed as formed intake components that accommodate engine movement, vibration, and thermal variation while preserving internal geometry critical to engine performance and emissions control.

Engineering & Material Performance

KOK air flow tubes are manufactured using elastomeric and polymer-based materials selected to meet OEM requirements for:

• Resistance to heat, oil mist, fuel vapors, and ozone
• Long-term flexibility and fatigue resistance under dynamic engine conditions
• Dimensional stability to support accurate airflow measurement
• Secure sealing at interface points with adjacent intake components

Material selection, compound formulation, and molding processes are controlled to ensure consistency and repeatability in series production.

Application Scope

KOK air flow tubes are supplied for:

• Passenger car air intake systems
• Automotive platforms utilizing flexible, formed intake ducting
• OEM engine architectures requiring controlled airflow paths

Both standard configurations and customer-specific geometries are supported, depending on packaging, performance, and regulatory requirements.

OEM Program Support

KOK supports OEM air intake programs from development through series production, working to align air flow tube designs with system-level requirements including packaging constraints, interface specifications, and durability targets.
