I have a little question. I installed hedders on my car and then the old sparkplug wires wouldnt fit so i used wires from a 1992 chevy van. Will that cost me anything in performance compared to the stock ones?

 

Seriously doubtful.

 

Yes thats why i asked this question. The engine runs really good but i dont know if it delivers enough power .
Any tips on wires that i can use?

 

It won't matter at all. Plug wires all vary in length for different engines. You can buy wires with the boots and ends unattached so you can cut them to the exact length you need. The only thing that changes is the resistance of the wire as the length is increased, typically 5k ohms/ft. That is not an issue to be concerned with unless the wire is 20ft long.

 

Thank you very much for your time and answer
