We would like to share our 15 years of experience with our clients and help them find the right part for the problem. This product has a low defect rate, but a high return rate from customers: Either clients are buying to resolve a spark issue that is not caused by the CDI box, or they are buying the wrong part for their make model and year.
Before purchasing please make sure to follow our advice:
- Always double check our pictures & fitments against the part you physically have on the vehicle (Our pictures are accurate).
- If you are buying this part for spark issues: these vehicles are notorious for stator failure, please make sure you have properly tested the stator before purchasing.
- Clients are buying this part for performance: Great add-on with an aggressive timing curve and increased rev limiter.
