Does the opti include the cap and rotor if you get it new from someplace like gmpartsdirect. Also, is it necessary to change the cap and rotor when one changes out the opti? Oh, what the heck does a cap and rotor do? I know what the opti does, but don't know the purpose of the cap and rotor. thanks guys

 

I'd suggest ordering from Jason Cromer or Dal. The price will be just about identical to GMPD minus the outlandish s&h charges.

A new opti will be assembled and ready to slap on.

 

What year is your car?

I have a non-vented opti that I ordered, and then ended up not needing it. I can sell it for $285 shipped.

 

I have a 95 bird...I need a vented opti. Thanks though.
