If you're reading zero Ohms, try a more sensitive meter. But the amount of energy lost to electric resistance in the spark plugs is not a large burden on the alternator, even with stock wires.

Most larger-diameter plug wires, and all capacitor-equipped spark plugs, belong in the Unicorn Corral. Especially Pulstar plugs, whose claims of scientifically proven fuel economy are based on defective testing in very unrepresentative engine loading conditions.

How many of you unicorns are there in the corral...anyway?

More almost every day...

And you need some resistance in your wires to reduce the EMI spike.

...and, it's also there to extend/lengthen the "arc-duration" after the initial "arc" is established.

...if you want more info on *why & how* I'll be glad to explain.

...Zero Ohm wires are OK for drag racing, but NOT for fuel economy!!

I'm pretty sure of the hows, just not the why's, so explain away.

Someone do some ABA testing on these! reviews are overall pretty good, but most people don't replace their plug wires when they should, typical gains are usually because the old wires were bad, not because the new wires are better than any other new wire (in my experience anyway).

I have been setting up ignitions for better spark with the following.

MSD or MALLORY Multi Spark Digital Systems. ( I prefer Mallory Digital.)

MSD Spiral Wound Universal Plug Wire Sets.

Non Resistive Spark Plugs : ie BP6ES.( For my engines.)

Spark Gap 0.050".

Brass center rotor contact and non resistive rotor.

This will give you a fat spark and correct Rf suppression without resistors in the plugs and wire ends like a lot of systems, ie : VW and Audi, pre COP Systems....or indeed the Carbon Saturated Wires.

Resistance kills spark power although giving RF necessary for today's computer wiring.

GM found some years ago that 0.100 ( One Hundred Thou. ) was the optimal spark gap for best initiation of compressed air/fuel mixtures. However, the gap was too large to sustain for long. ...so now they run 45thou to 60thou gaps.

You have to run resistance in the ignition system to comply with Federal Law.
A resistance load will give you a higher voltage spark up to a point.

If you cannot afford a MSD/MALLORY use a GM ignition system.

If you Google 'Ignition' or 'GM Ignition' there are a couple of sites detailing how to install a GM power unit and HP Coil to most any type ignition.

Next best system, although a little dated now was the Dodge type.....1975 up to around 1980 'ish. All salvageable from your local wrecking yard.

Another company used to sell Variable Coils...Jacobs Ignition. You can still find these on eBay and Craiglist for time to time. They seemed to work well but died due to people installing them in hot engine bays....they need cooling, just like the MSD/MALLORY does.

I installed a MALLORY on a NPR truck that I installed a 360ci Dodge engine in last year and it's still going strong but I installed the spark unit on the chassis rail away from the engine heat.

increasing spark energy potential to the plug is helpful to a more efficient cylinder firing event but only to a point.

the way i see it, low resistance wires and hi output coils do not add efficiency, but rather they help prevent the loss of same.

if your spark plug can produce a sufficient arc with the existing factory designed equipment, then the upgrades to wiring or coil are not needed.

BUT, if you put higher strains on the spark plug's ability to arc that gap to the point of misfire, like increasing compression ratios, turbocharging or supercharging, altering fuel ratios, enlarging plug gaps THEN ignition wire and coil upgrades make sense.

Multiple Spark Discharge boxes are another thing... they do help improve low rpm cylinder firing and can help improve economy since they are in effect throwing numerous arcs.

The simplest way to upgrade your ignition system is to 1. increase spark plug gap, 2. use the thinnest wire electrode spark plug available. and 3. index your spark plugs if they are not centrally located in the cylinder.

IF your ignition cannot hold up to the increased demands now asked of it thru the increased gap, then look to fix the problem in the system that is breaking down first. Typically it's the spark plug wires first, the coil second, and the ignition design limitations third.
