Automotive Spark Plug and High Performance Wires
Conversion Kit
NEW, UPDATED AND REDESIGNED KIT.
CLICK HERE FOR A COPY OF THE INSTALLATION INSTRUCTIONS.
WORKS ON ALL M14 POWERED AIRCRAFT AND
ON THE NANCHANG CJ6 HUOSAI ENGINE AS WELL.
The kit price is $399 plus $24 shipping,
insurance to a U.S. address. A $12 handling fee is charged for
all on-line credit card payments.
Contact me for shipping rates outside the U.S.
The kit includes everything you need to complete
the conversion, including the spark plugs of course. The spark plugs
are over-the-counter NGK automotive spark plugs. Typical cost for
each plug is about $2.25.
The wires are 8 mm Taylor Spiro Wound racing wires custom manufactured for
me by Taylor Cable Products. With regards to RFI,
the Taylor Spiro Wound wires are designed to eliminate RFI. I have
experienced no noise whatsoever in my personal Yak 52. Here's how the
Spiro Pro wires eliminate RFI as explained by a Taylor engineer.
"Electronic filtering is possible due to two types of components. They are
capacitors and inductors. Capacitors like high frequency, and will allow it
to pass, while they hate low frequency, and will reject it. Inductors like
low frequency, and will allow it to pass, while they hate high frequency,
and will reject it. The Spiro Pro wires are constructed in such a way that
they have a certain ratio of capacitance, and inductance. This causes the
wires to be a high impedance to high frequency, (which is RFI). They will
allow the D.C. component of the firing signal to pass through while blocking
the A.C. component, (the part that causes RFI). The composition of the
core, the thickness of the core, the size of the conductor, the permeability
of the core, the number of turns per inch, etc., all have a direct
relationship on the suppression factor of the wire."
The following
bullets are taken directly from the Taylor web site.
- Spiro-Pro wires provide more fire power to the spark
plugs than OEM resistor core wires and up
to 10 times less resistance than standard resistor core wires
- Spiro-Pro eliminates radio frequency interference
(RFI) and is a must when using a multi-spark
discharge ignition system, electronic ignitions, and on board
computer systems
- Spiro-Pro’s two layers of 100% pure silicone makes it
the highest temperature rated wire on the market
(600º F) without the need for additional sleeving
- Features Taylor Cable’s EXCLUSIVE low profile, 100%
silicone PRO BOOT® with grips and vibration proof
double spring locking spark plug terminals
The wires are cut precisely to length
for each and every cylinder for both mags. Since 8mm wires are
slightly larger than the holes in the mag cap, the kit is supplied with a drill bit which is used to
drill the magneto distributor cap holes to the proper size. Since the
magneto distributor cap material is relatively soft, drilling the cap is
quite easy. The front plug wires are marked "1" through "9" and each
front spark plug wire has a red band on it to signify the front plug wires.
The rear spark plug wire set does not have a red band on each wire and each
wire is also marked "1" through "9".
The kit includes a sufficient number of tie wraps to dress out the wires
and to hold the rubber hose pieces in place through the baffling. The
instructions are precise and include color photos of the installation which
are now provided in the kit on a CD.
To facilitate the installation into the magneto through the front cover, one
must grind out a small amount of metal inside the hole of the front cover of the
mag. The 8 mm wires (vs. 5 mm standard Russian wire) won't quite go
through the cover otherwise. It's very easy to do with a Dremel tool,
die grinder or
something similar. The material that is removed inside the hole of the
front cover is excess metal and has no impact whatsoever on the strength and
rigidity of the front cover. The wires fit though this hole very snugly.
Removing the Russian wiring harness takes time. There are 4 metal tabs
on the ring that bolts to the case. The 11 mm nuts holding the ring
tabs are removed with a 1/4 drive 11 mm
socket and extension. I have found that a flex or swivel 11 mm socket
works best. The ring splits in half at the top and the large
braided shield that goes from the ring to the mag cover is also completely
eliminated. Once the Russian wiring harness is removed, the reassembly is
quite nice. You'll be amazed how much more room you have without the
Russian wiring harness in place.
You have the choice of reusing the metal clamps that hold the original,
braided spark plug wires or tie wrapping the wires to the intake tube using
the supplied rubber hose. Either way works. Since the intake
tubes are "cool" compared to the exhaust temperature, there is no problem
with heat concerning the wires when they are affixed to the intake tube
using the rubber hose and tie wrap.
After installation, on my first attempt to start the engine, I BARELY
touched the start button and the engine fired up instantly. The best it EVER has. I
couldn't believe it! The idle is really smooth, which I attribute to
a hotter spark. The mag drop is 2% or less. Again, better than it
ever has been. It accelerates better and just feels like it has more
power. The guys I fly with tell me I do get off the ground quicker than
they do, given similar gross weight etc.
I hope this answers most of your questions. In my mind, it's the best
conversion for this engine and the cost is less the the cost
of one set of Russian or Chinese spark plugs. If you're interested in
a kit, send a check made out to me for the $423.00 (which includes the
shipping and insurance to US locations) to my address
