Anyone know the best/cheapest place for a non vented GM optispark?

 

If I had to buy one, I would get the MSD unit from Summit Racing or maybe Jegs. You get the vent upgrade with these plus they are listed for a cheaper price than the GM non-vented units last time I checked.

 

Try that Chandler Motorsports one right here to the lelt on this page 85.00

 

Chandler is NOT OEM. The lowest OEM price I found so far is gmpartsdirect.com. $431.60

Way too many people have problems with MSD.

You may consider just the cap and rotor if you have no issues with oil leaks. I had great results from this:

The 2 opti's are different. the early model(non-vented) one is spline driven, and the later model(vented) one is pin driven. I bought the vented one from O'reillys for around 100 bucks, with a lifetime warranty.

 

and howd that work out for you?

 

Check Rock Auto and Amazon. Keep in mind the non-vented is higher than the vented.

 

i like my msd one, its not the billet one tho, but its been through a lot and works well still

 

correct....all the pain of changing an opti get a GM unit or go home. MSD = hit or miss

 

I need a vented opti and was on chandler motorsports eBay site I didn't see any optis at that price. Did they raise their prices?

 

look up delphi on ebay. there is a guy selling them for $333 shipped
