Nology Spark Plug Hot Wires.......
On ebay there are these NOLOGY SPARK PLUG HOT WIRES and i would like to know if they really make the combustion spark greater. If they do then wouldnt that mean more power. If its true would our 8's be able to handle them. If anyone has any NOLOGY SPARK PLUG HOT WIRES there experience would be great.
Thanks
Thanks

uhh...i dont know why you guys had problems but my friend and i both have nology hotwires in our 8s and its really great....i really do save more gas....a significant amount and plus you can feel a better throttle response in the car. if your car is barestock, you can hear the engine sound a little different. thats cause its getting ignited at a greater power. i say go for it. defnitely worth the money.

"CAPACITOR" EFFECT WIRES with grounded metal braiding over jacket
The most notable of exaggerated claims for ignition wires are made by Nology, a recent manufacturer of ignition wires promoted as "the only spark plug wires with built-in capacitor." Nology's "HotWires" (called "Plasma Leads" in the UK) consist of unsuppressed solid metal or spiral conductor ignition wires over which braided metal sleeves are partially fitted. The braided metal sleeves are grounded via straps formed from part of the braiding. Insulating covers are fitted over the braided metal sleeves. These wires are well constructed. For whatever reason, Nology specifies that non-resistor spark plugs need to be used with their "HotWires." In a demonstration, the use of resistor plugs nullifies the visual effect of the brighter spark.
Ignition wires with grounded braided metal sleeves over the cable have come and gone all over the world for (at least) the last 30 years, and similar wires were used over 20 years ago by a few car makers to solve cross-firing problems on early fuel injected engines and RFI problems on fiberglass bodied cars — only to find other problems were created. The recent Circle Track Magazine (USA, May, 1996 issue) test showed Nology "HotWires" produced no additional horsepower (the test actually showed a 10 horsepower decrease when compared to stock carbon conductor wires).
The perceived effect a brighter spark, conducted by an ignition wire, encased or partially encased in a braided metal sleeve (shield) grounded to the engine, jumping across a huge free-air gap (which bears no relationship to the spark needed to fire the variable air/fuel mixture under pressure in a combustion chamber) is continually being re-discovered and cleverly demonstrated by marketers who convince themselves there's monetary value in such a bright spark, and all sorts of wild, completely un-provable claims are made for this phenomena.
Like many in the past, Nology cleverly demonstrates a brighter free-air spark containing useless flash-over created by the crude "capacitor" (effect) of this style of wire. In reality, the bright spark has no more useful energy to fire a variable compressed air/fuel mixture than the clean spark you would see in a similar demonstration using any good carbon conductor wire. What is happening in such a demonstration is the coil output is being unnecessarily boosted to additionally supply spark energy that is induced (and wasted) into the grounded braided metal sleeve around the ignition wire's jacket. To test the validity of this statement, ask the demonstrator to disconnect the ground strap and observe just how much energy is sparking to ground.
Claims by Nology of their "HotWires" creating sparks that are "300 times more powerful," reaching temperatures of "100,000 to 150,000 degrees F" (more than enough to melt spark plug electrodes), spark durations of "4 billionths of a second" (spark duration is controlled by the ignition system itself) and currents of "1,000 amperes" magically evolving in "capacitors" allegedly "built-in" to the ignition wires are as ridiculous as the data and the depiction of sparks in photographs used in advertising material and the price asked for these wires! Most stock ignition primaries are regulated to 6 amperes and the most powerful race ignition to no more than 40 amperes at 12,000 RPM.
It is common knowledge amongst automotive electrical engineers that it is unwise to use ignition wires fitted with grounded braided metal sleeves fitted over ignition cable jackets on an automobile engine. This type of ignition wires forces its cable jackets to become an unsuitable dielectric for a crude capacitor (effect) between the conductor and the braided metal sleeves. While the wires function normally when first fitted, the cable jackets soon break down as a dielectric, and progressively more spark energy is induced from the conductors (though the cable jackets) into the grounded metal sleeves, causing the ignition coil to unnecessarily output more energy to fire both the spark plug gaps and the additional energy lost via the braided metal sleeves. Often this situation leads to ignition coil and control unit overload failures. It should be noted that it is dangerous to use these wires if not grounded to the engine, as the grounding straps will be alive with thousands of volts wanting to ground-out to anything (or body) nearby.
Unless you are prepared to accept poorly suppressed ignition wires that fail sooner than any other type of ignition wires and stretch your ignition system to the limit, and have an engine with no electronic management system and/or exhaust emission controls, it's best not to be influenced by the exaggerated claims, and some vested-interest journalists', resellers' and installers' perception an engine has more power after Nology wires are fitted. Often, after replacing deteriorated wires, any new ignition wires make an engine run better

I guess I should take mine off my car ASAP? I really could not tell a dif anyway! Been on the car for about a year now... are RB any better? What kind do you rec?

Wires are not a mod that will increase horsepower. Ideally you should replace them whenever you replace your plugs.

Sports Car magazine just did a review of mods you can make to a stock class SCCA solo car - air filter and wires. It just so happened they used an RX-8!
They base lined the car the way it ran (and won) it's last event dirty K&N panel filter and upgraded Taylor 8mm wires from Mazda Motorsports. The car pulled consistently on the dyno to 7200 rpms and then the dyno would either stop reading, cut in and out intermittently or give totally dissimilar results. They switched to Nology wires and the dyno pulled clean to 9K every time - NO power increase though.
If you're interested: new Mazda air filter = 2hp, new K&N = 5hp, new Green Filter = 7hp.

So all that story proves is that the taylor wires are very well insulated, and the nology wires are crap and probably interfering with other electrical systems throughout the car.

Savedsol,
Where the K&N filter which gave 5hp increase and the Green filter that gave 7hp both flat panel filters?
If so, I'll definitely be tracking down a replacement green filter pronto.
Anyway that you can scan the article for us to view? We dont get this Magazine in OZ.

Rexi

Just a note about Nology's own description of their wires... Capacitance in plug wires would be considered parasitic capacitance (which is bad..) The only reason I can think of that the spark may appear brighter is that the wires capacitance makes the spark fire longer or multiple times (if the wires are resonant,) though most likely not as hot (slightly retarding the ignition, and possibly adding some variability to it.)

expo1: Thanks for the great quote! Lots of info... To summarize, nology wires will put even more strain on a factory ignition system that's barely keeping up to begin with.... Good buy if you want to keep swapping out coils...
