KOK Air Flow Tubes
KOK designs and manufactures air intake hoses for OEM motorcycle and automotive applications, where airflow stability, material durability, and dimensional consistency are critical to engine performance and emissions compliance.
KOK air intake hoses are engineered as functional components within the engine air management system, connecting intake, throttle body, and air filter assemblies while accommodating vibration, thermal variation, and engine movement over the vehicle's service life.
Application Scope
KOK air intake hoses are supplied to OEM programs for:
- Motorcycles and scooters
- Passenger cars and light automotive platforms
- Recreational vehicles
- Engine air intake systems requiring formed, flexible hose solutions
Both standard and customer-specific hose designs are supported, depending on platform architecture and performance requirements.
Engineering & Material Performance
KOK air intake hoses are developed using elastomeric and polymer-based compounds selected to meet OEM requirements for:
- Resistance to heat, oil mist, fuel vapors, and ozone
- Long-term flexibility under repeated thermal and mechanical cycling
- Stable internal geometry to support consistent airflow characteristics
- Secure sealing at connection interfaces under dynamic operating conditions
Compound formulation, reinforcement strategy, and molding processes are defined and controlled by KOK to ensure repeatable performance in series production.
OEM Program Support
KOK works closely with OEM customers during development and production phases to align air intake hose designs with system packaging, material specifications, and validation targets. This includes support for custom geometries, interface requirements, and durability expectations relevant to modern engine platforms.
