If you're wrestling with an LT1 engine from a '90s Chevy, Buick, or Pontiac, you know the Optispark can be a headache.

But this FTG brand new harness (part #Optiharness1) makes it a little less painful.

It’s a direct fit for that 5.7L V8, replacing old crusty wires with fresh ones.
The interchange numbers are 1104032 and 108097, so it matches up with the factory stuff.
It's brand new, still in the package, ready to be installed.

No more chasing misfires from bad wiring—this gets the spark to where it needs to go.
