H1C1 Component for Distributors

Aftermarket replacement H1C1 control board - controls communication of the engine position sensors. If you've replaced distributors and still have a CEL, this is probably your problem! This part is used to attempt repair on ECUs with CEL codes 4, 8, and 9.

Not compatible with ecu's using H1C1 boards labeled NY1BG or NY1DG, it is very rare for your ecu to have these models, if so please contact us before purchase.
