not necessary if you use a non chinese vented oem version with mitsubishi optical sensor (add vent if you have a 92-94 unvented )

Enjoyed the styling and driving of my C4s (14 years), but the best opti conversion I found was a C5 and newer.

I have a 93, can you add a vent without removing the opti spark from the car?

That should help the OP.


OP several members have tried that system....I don't recall hearing of any issues with it. If you do a search, I'd expect that you'd find the threads covering the swap. You could PM or email those members and ask for updates....

You can use the MSD 8481 kit.
