I have a 93 Firehawk M6 with 132K and has the orginal optispark. The opti needs to be replaced. Should I do the vented opti upgrade or stay with the OEM non vented. I got 132K out of the non vented opti so they must not be to bad. I will be going with the AC Delco unit either way.

Thanks

If you are not intending any of the necessary changes you need to make to go vented, then I would say no. You could always do a vented MSD cap and rotor kit on the AC-Delco unit.

 

Thanks shoebox, thats a good idea. I saw some new Delphi optis on Ebay for 325. I thought that was a decent price for the non vented.

 

delphi ftw, i got mine for 360 with a 3 year warranty so if ur gettin a warrant for 325 i say your gettin a good deal.

 

look into chandler motorsports optis

 

I'd recommend the Delphi over the Chandler any day. Way too many bad reports on CMS.

 

Ditto.

 

when i was looking at optis i gave the cms a thought...googled the name found a couple threads on various forums that made me forget about it and get the delphi
