FLO Headworks is now dual plugging all
Harley-Davidson models from Knucklehead through Evolution.
After more than 25 years of working on
Harley engines of all types, we thoroughly understand Harley’s
built-in detonation problem (see our Detonation article). Starting in
1982 we developed the solution that now works across the whole model
range: dual plugging.
Here’s the source of detonation in your
Hog: The deeply concave combustion chamber in the cylinder heads keeps
the flame from traveling across the entire combustion chamber. Today’s
lower-octane, no-lead gas makes detonation worse, and causes valve seat
overheating, too. The worst thing is, your engine could be suffering
from detonation and you don’t know it—pinging isn’t always
audible. But if it is, your power will be down, and overheating will
prematurely wear out your top end components. |
The test results of our Dual Plugging Kit
have been impressive. With 15, 000 Volts output from the coil, using our
Dual Plug Wire Kit and Coil
Kit we guarantee our Dual Plugging process will eliminate detonation,
spark plug fouling and hard starting, and increase horsepower by
at least five percent,
In addition, you’ll enjoy increased gas
mileage—up to eight percent according to some tuners. You’ll double
the life of your spark plugs, and lower emissions.
Dual plugging is especially effective
with high-performance cams. Steel thread inserts are used on Panhead,
Shovelhead Evolution Big Twin and Twin Cam.
Our work and products are guaranteed for
one year. For an estimate on your particular application contact us
