The wires came with very straight-forward instructions. It even included a
separate sheet warning about the non-ribbed insulator of the Splitfire sparkplugs.
Installation was a breeze. Just
be careful about pulling out the old wires and remember to mark the locations
where each wire was pulled from.
Here is the measured resistance of each wire. Acura states that the specification
for the stock wires should be "less than 25 Kohm at 68deg F (20deg C)". Here are
the actual measured values.
Stock 8-12 K Ohms
NGK Blues 4-6 K Ohms
Magnecor 8.5 3-5 K Ohms
The difference between the 8.5 mm and 10 mm Magnecor wires is the
thickness of the insulation and the price. However, the thickness of
the insulation allows the 10 mm wires to have better heat resistance
and a higher dielectric strength. Magnecor does make wire guides for
their 10mm wires.
KV85 (8.5mm) R-100(10mm)
Service Temp. 600 F 700 F
3 Minute Temp. 1,000 F 1,200 F
Dielectric Str. 60kV at 260 C 80kV at 260 C
As expected, performance improvements were not noticeable even by the
G-analyst. This is to be expected since my car has only 20,000 miles
and I'm sure the stock wires are still good.
- Good fit and easy installation
- Good replacement for old, worn out stock wires
- A must for capacitive discharge ignition systems
- Does not affect stereo performance
- No noticeable acceleration improvements compared to new stock wires
A good replacement when your stock wires are getting tired or when you move
up to a capacitive discharge ignition system.
Magnecor's Evaluation of RFI
by Richard Cox/Steve Brown
We rarely have anybody comment that Magnecor Race wires cause RFI
interference, even though the wires are primary designed to eliminate
EMI, and that's why we're curious about your problem.
Aftermarket AM radio/sound systems are inclined to pick-up RFI from
ignition wires because the AM tuners used are generally not as capable in
picking up the signal from the radio station as the original sound
system's tuner. Better AM tuners overcome RFI noise picked up from
ignition wires by drowning out the ignition noise with a strong signal.
It's important that no part of the antenna cable is in the engine bay,
and that you establish that the antenna's outer sheilding is grounded to
chassis or body. Also, make sure the antenna and its cable inner wire (in
which the signal travels) are intact to the set and there's no corrosion
at any connections, or water in the antenna housing or that the antenna
lead or power lead to radio is close or attached to the tachometer lead.
All the aforementioned will weaken the signal from the radio station to
the AM tuner.
If the noise is a ticking sound, as though it's only coming from one or 2
cylinders at idle speed (listen with radio off a station), it could be
that terminals at either end of ignition wires are not all the way
connected onto spark plugs and distributor/coil.
Also, re: Nology HotWires. They consist of nothing other than grounded
metal braiding over part of the ignition wires' insulating jacket.
There's no separate capacitors included with the wires. The bits that
screw on are usually European connectors (with resistors inside). We at
Magnecor don't recommend capacitors be fitted to any ignition wires.
Metal braiding over ignition cable does cause a crude "capacitor" effect,
which is of no use to your engine even if is was true it could shorten
the spark duration (which is controlled solely by the ignition
amplifier), as your engine runs best with the spark duration as close as
possible to the original ignition. Integras don't like Nology HotWires,
as all sorts of nasty things happen as the ignition cable's jacket under
the metal braiding breaks down and eventually more and more spark energy
is induced into the metal braiding, leaving little to fire the spark plug
We have never heard of RFI noise from ignition wires causing a "whistle"
(usually associated with an alternator). Ignition wire noise can be
identified from other noises because of it's a sharp ticking noise that
gets faster as engine revs increase. A bad coil wire connection could
sound like a ZZZZZZZZ. (again changing with engine revs).
As our previous e-mail mentioned, AM noises are more likely than not the
result of a weak or badly shielded radio signal in the antenna (not
necessarily the Alpine set), and the set's tuner picks up ignition wire
and other noises in preference to the radio signal. The more energy the
ignition wires can handle, the more RFI noise the tuner is inclined to
pick-up from wires in preference to a weak radio AM signal. We also
suggest you check the connections at the spark plug end and distributor
ends of the ignition wires just in case they're loose.
