The module has passed FCC testing and is designed to operate dependably across normal ATV conditions.

Will this CDI fit my 1995 Fourtrax TRX300?

If your ATV is a Honda Fourtrax 300 or TRX300 produced in the 1994–1997 window, this OLIFANT CDI is engineered to be compatible. It uses the same connector layout and electrical characteristics as the original part.

• Direct-fit for TRX300 (2x4) and TRX300FW (4x4) models.
• Connector configuration: 4 pins + 2 pins to match factory harnesses.
• Cross-references Honda part numbers listed above for verification.

How does this CDI affect starting and throttle response?

The CDI controls ignition timing and the pulse sent to the spark, which helps ensure consistent starting and responsive throttle behavior when the rest of the ignition system is in proper condition. Replacing a failing CDI can eliminate intermittent misfires and unstable idle that originate from timing irregularities.

• Delivers stable ignition pulses for improved cranking consistency.
• Helps reduce misfires caused by a weakened or faulty ignition module.
• Works with existing stator, coil and spark plug systems—no additional tuning required.

What are the build and safety highlights of the OLIFANT unit?

OLIFANT manufactured this CDI using upgraded semiconductor chips and robust housing to withstand vibration and typical ATV environmental exposure. The module has passed FCC certification, and quality control focuses on reliable operation under varied temperatures and running conditions.

• Durable components and precision assembly for long-term reliability.
• Protective housing to resist vibration and moisture intrusion in normal use.
• FCC-tested electronics for consistent electrical performance.

How easy is installation and what should I check first?

Installation is straightforward for anyone comfortable working with ATV electrical connectors: unplug the old CDI, match the 4-pin and 2-pin connectors, and mount the replacement in the original location. Before replacing the CDI, inspect the stator, ignition coil and wiring for damage or corrosion to avoid diagnosing the wrong component.

• Swap directly into the factory mounting bracket and harness—no modifications typically needed.
• Verify connector pins and harness condition before installation.
• Test with a fresh spark plug and known-good battery if starting issues persist.

Who is this for: This OLIFANT CDI box is intended for owners and mechanics maintaining 1994–1997 Honda Fourtrax 300 ATVs—both TRX300 (2x4) and TRX300FW (4x4)—who need a reliable, drop-in ignition module to replace a worn or faulty OEM CDI. It's also suitable for shops and restoration projects that require parts cross-referenced to Honda numbers 30410-HM5-671, 30410-HM5-672, 30410-HM5-670 and 30410-HM5-505 and want an FCC-tested aftermarket option with durable components.
