Can you do with out the spark plug boot? Will it do any harm if you have 0 ohm resistance between cap and plug? I am trying to be cheap with out doing any harm to the car.

What do you think happens with no boot at all?

I am talking about the spark plug connector. It is seperate from the wire that has it's own boot. The connector adds 3K ohms of resistance. My Question is why is resistance needed and can you eliminate it?

Due to the higher voltage of electronic ignition, resistance is needed for suppression of both RFI (radio frequency interference) and EMI (electromagnetic interference).

if your going the cheap route find someone thats parting out a similar model they might have a good set of wires that will work , and you can keep the original parts on your car for continued use, you may have to do some searching.
So asking the obvious , whats the year and model of your car auto/5 speed?? miles, options? and the projected use.
This info may get your question answered faster..... Remember the more info you put in a post the higher the possiblity that a more effective answer can be generated

By the way if thats your car in the avitar it looks good

Thank you for your help. I have been a member for over a year and could not be happier about the help and camaraderie found here at Rennlist.

Matt,

I have a good set of used wires. I only replaced them because it was for my track car and I replaced everything in sight trying to rule out a fuel problem I was having.

Yours for free if you can use them.

Free is a decent price....

The resistance in the plug connector is there to increase the firing current available. The ignition coil voltage and current increase in a curve, with the ideal firing point somewhere just before the peak voltage and current point. Using the resistor causes the firing point to be a tad later, a little higher on the discharge curve of the coil. So beyond the EFI and EMI issues that affect radios and other electronic bits in the car, there's a definite performance reason for using the correct plug connectors -- the coil characteristics require them for correct performance.

Dr Bob thats some interesting info.
Tass without a doubt, thats a nice gesture for Hagen...
See Hagen your word has given you what you need now, and you get original parts, good luck!

Dave,
If Matt doesn't take you up on your offer, I'd like to.

I have an intermittant problem I think is in the wires, but they look good, and I hate to invest in a new set only to be wrong.

Michael,

I did take him up on his kind offer. If I may suggest that you should ohm test the boot connectors for resistance. My car would break up intermittantly, one or more spark plug boots were bad. You should get a ressitance reading of around 3k ohms. I now have a few good ones that I took off the car. I will pay it forward and mail them to you. Send me a PM with your address.

Thanks Matt,

Did a check yesterday and I can see the resistance in the coil wire change significantly when I bend it.... so I believe I've just got a bad set. Did you try to unscrew the wire from the ends? I've seen that economy set that is supposed to thread into the resistors in the caps, but it felt like the wire was about to break when I tried to unscrew it. I'll go search for a better description somewhere so I can make more sense of it before I mess up a resistor.

PM sent: Thanks!

Dave,
Again I can't thank you enough for the wire set! The car purrs like a kitten and no longer breaks up when I pull it's tail.

Michael,
I mailed the spark plug boots on Saturday via USPS. I hope they solve your problem.
