Does this include the wiring harness adapter or do I need to buy that separately?

Asked by JACK on August 21, 2017

Mine did not include the wiring harness. I re-used the wiring harness of the OEM Optispark. I bought quality spark plug wires and replaced the originals. I also made up new vacuum hoses for the 2 vacuum ports. I am pleased with this optispark and my installation.

SHAUN from FL answered on August 25, 2017

Separately

DIONTE from WI answered on September 05, 2017

MATTHEW from GA answered on August 25, 2017

Only hardware is included. You need to buy all wiring and/or adapters separately.

Is there a difference between the optispark 1 and optispark 2. Can I put an optispark 2 on a stock lt1 motor from a 93 camaro?

Asked by MICHAEL on September 13, 2017

The earlier optisparks, 92 - 94, were spline driven. The later optisparks, 94 - 97, were pin driven. So the answer is "NO".

SHAUN from FL answered on September 25, 2017

no92-93feature a splinedhole in the centerof the cam gearthat drives the distributor the later ones have abigger center pilothole to center the dist.drive and a longer dowel pin that drives the dist.

TIMOTHY W from MA answered on September 24, 2017

You can not use an opti 2 on 1993 Camaro unless you change the timing cover and the pin in the end of the camshaft. So the short answer is not it will not work on 1993 or 1994 Camaro or firebird.

MATTHEW from GA answered on September 24, 2017

Opti 1 is not vented. Opti 2 is vented with vacuum lines.

Excellent quality and priced right. Car never ran better. Got average score for "ease of installation" only because GM put it behind the water pump. lol

I have a 95 Formula, 136,000 miles. Started running poorly...Original Optispark was the issue. Did my research. Delco and MSD very pricey. All other (cheaper) brands had horrible reviews. I've always had good luck with Summit products decided to go with the Summit. Product was packaged great, arrived timely. Install was easy. I suggest ordering the water pump seal and distributor seal when doing this job. Did the plug wires as well. Car fired right up, runs phenomenal. Did the install on Sunday afternoon. Drove the car 300 miles the next day. For the money, it's a great product. Highly recommend it. ...read more

This is the second summit Optispark I purchased. The last one was installed as a part of my 150k service in June 2013 by a qualified shop.. The first one failed! I ordered another one because the firing problem could have been something else. It seems to have fixed the problem. If it happens again I will know better and have to try a different manufacture.... Installing it requires removing the water pump and the dampner. So the install is a pain.. That is GM's fault not the product.. ...read more

Did a lot of research looking for a new optispark. This one seemed to be one of the most recommended. So far about 1000 miles in it and no problems. I did open it and put loctite on the rotor screws.
