from what i remember the opti is still there but it does not use the high voltage in the opti, its passed to the coils. Which drastically prolongs the life of the opti (still have to worry about the water pump tho).

Edit: this is on the part information

This unit still uses the factory optical module in the Optispark for reference, but no high voltage is passed through it. This removes the source of damaging ozone that eventually leads to Optispark failure.
