The Honda 30401-KYY-900 Ignition Control Module CDI Cushion is a genuine OEM component designed for EX3300 and EX4500 generators and the EXW171 welder generator. Sourced directly from Honda, this cushion delivers the exact fit and material properties the original design calls for. Verify your unit's serial number against the fitment table before ordering, as Honda supersedes parts at specific serial breaks.
Key Features
- Genuine Honda OEM — sourced directly from Honda, matching the original specification for part number 30401-KYY-900 with no guesswork on fit or form.
- Vibration and Shock Isolation — this cushion mounts between the CDI unit and its housing to absorb vibration and mechanical shock, protecting the module from premature failure caused by engine-induced stress.
- Broad Generator Fitment — designed for EX3300 and EX4500 generators and the EXW171 welder generator; confirm your serial number against the fitment table to ensure this is the correct part for your unit.
The Ignition Control Module CDI Cushion is a rubber isolation mount that sits between the CDI (Capacitor Discharge Ignition) module and its mounting point on the generator. Its role is to absorb vibration and dampen mechanical shock that would otherwise transfer directly into the CDI unit during operation. Without this cushion in good condition, the CDI module is exposed to sustained vibration that can loosen connections, crack solder joints, or cause early electronic failure — leading to hard starts, misfires, or a complete loss of ignition.
