For Honda IAT Weld Flange Bung B16 B20 B18 D16 K20a K24 (aluminum) intake air temp
Description
IAT Weld Flange Bung for Honda/Acura – Fits B16 B18 B20 D16 K20 K24 OBD1
Upgrade your intake system with this CNC machined aluminum IAT weld flange, designed to relocate your Honda/Acura OBD1 intake air temperature (IAT) sensor to a more accurate location on your intake or charge piping.
✅ Product Features:
-
Precision CNC machined aluminum flange
-
Ideal for turbocharged, supercharged, or custom intake setups
-
Compatible with Honda/Acura B-Series, D-Series, and K-Series engines
-
Designed for OBD1 IAT sensors
-
Allows secure relocation of sensor to avoid heat soak issues
-
Prevents false ECU readings due to high manifold temps
-
Requires welding – not a bolt-on part
🛠️ Why You Need This Flange:
In forced induction or performance builds, heat soak from the factory aluminum intake manifold can lead to inaccurate IAT readings. This flange lets you relocate the IAT sensor closer to the throttle body or in the intake piping, where air temps are more representative — giving your ECU the correct data for safer and more efficient performance tuning.
It's also a perfect solution for:
-
JDM intake manifolds that lack an IAT mounting point
-
OBD2 conversions needing IAT placement in charge piping
-
Preventing blowout under boost pressure
📦 What's Included:
-
(1) CNC Aluminum IAT Weld Flange (OBD1 style)
-
(2) Allen Head Bolts for sensor retention
🚗 Fitment / Compatibility:
Engines:
• Honda B16, B18, B20
