This OEM-grade 60mm electronic throttle body assembly is a direct throttle body replacement for Honda Accord, Civic Si, CR-V, Element, and Acura CSX with 2.0L/2.4L K-Series naturally aspirated engines (K20Z2, K24A8, K24Z1, K24Z4). Whether you need a full throttle body replacement after throttle body actuator failure, a throttle body tps sensor fault (P0120, P0121, P2100, P2119, P2135), or a scheduled throttle body service, this unit is engineered to Honda OEM specifications for precise throttle response and long-term reliability. The die-cast aluminum housing and Viton throttle body gasket seals ensure airtight fitment with no wiring modification required. Please verify your OE number before ordering.


  • OEM-Grade Throttle Body Assembly – Direct replacement; resolves issues that throttle body cleaning alone cannot fix.
  • K-Series Optimized – Engineered specifically for Honda/Acura 2.0L and 2.4L K-Series engines.
  • Dual Redundant TPS (Throttle Body TPS Sensor) – Prevents idle fluctuations, hunting, and false error codes caused by a faulty throttle body position sensor.
  • Viton Gasket & Seals – Oil-resistant fluorine rubber for long-term airtight fitment.
  • 100% Factory Tested – Thermal cycling, airtightness, and full throttle body actuator stroke calibration before shipment.

  • Bore Size: 60mm
  • Connector: 6-Pin (Honda K-Series)
  • Engine: 2.0L / 2.4L K-Series (K20Z2 / K24A8 / K24Z1 / K24Z4)
  • Housing: Die-Cast Aluminum Alloy
  • Seal / Gasket: Viton
  • OE Ref: 16400-RAA-A21 / 16400-RZAA01 / TB1245 / 672004
  • Warranty: 12 / 24 Months

A throttle body relearn procedure is required after installation to recalibrate the throttle body position sensor baseline — this is standard throttle body service practice for Honda K-Series platforms. Disconnect battery for 5–10 minutes before installation. Install a new throttle body gasket (most aftermarket units include one). Turn ignition ON (do not start) for 10 seconds, then OFF for 10 seconds. Start engine and idle for 5 minutes without touching the accelerator. If issues persist, use Honda HDS scanner to perform “Throttle Body Learn” or “Idle Relearn”. Non-professionals should not attempt installation.
