Optispark and vacuum lines seperate or in bundle. Correct sizes and seems to be quality from description. And they loctite the screws. Petrisenterprises.com

 

Are you giving a review of a product or asking a question about it? Could you please clarify?

 

Both in a way, seems to have good details on things that are needed.

 

If you're asking if the optispark is a quality unit, I believe it is. There are very few businesses/people that make quality optisparks, from my experience so far Petris Enterprises seems to be very good. I installed one just a bit ago and it immediately cleared up a small miss at idle compared to my previous unit. The hoses and everything included feel very quality and fit everywhere just as they should. The kit even comes with a protective piece that slides over them that you can put over any areas where the vacuum lines may rub. There are quite a few design improvements that will hopefully improve the longevity of the opti, I have had no issues yet.
