Has anybody used one of these? Is it worth the money, or sould I get a factory gm piece?

 

If the car still runs without any opti codes get a MSD cap and rotor. If the opti is setting codes get a new stock opti.

 

Oem.

 

Thanks.....

Very informative link, thanks. I just replaced my Opti unit about 5000 miles ago and now I have trouble starting the car. I think there is moisture in the cap. Now it all has to come apart again, and I guess I have to buy another one....
