Frequently Asked Questions
Q: Why do PowerSTAR spark plugs look different and what does the “STAR” do.
A: The PowerSTAR spark plugs look like your ordinary spark plug
except for the tip. The STAR shape creates multiple point gaps that
allow for faster starts and less fouling. Multiple point gaps allows the
spark plug to ignite on more then one point gap and create the heat
necessary to ignite the air fuel mixture. Unlike conventional spark
plugs the PowerSTAR plug doesn’t fire from a concentrated point tip it
is spread out in a large 360-degree dispersion area.
Q: What is indexing and why do you need it?
A: Indexing refers to the orientation of the “J” or “L” shape ground
electrodes in the combustion chamber. When the spark fires in a
conventional plug the expansion of the flame kernel is blocked by the
"J" ground strap. This slows the expansion of the flame kernel, slows
the progress of the burn and doesn’t allow the most horsepower and
torque from one spark. Racers place washer stacks to change the
orientation of the ground to optimize the burn. PowerSTAR spark plugs
generate a flame front from all points of the star over a much larger
surface area. This generates a larger faster flame kernel from all
sides. This is what helps to give your engine more power.
Q: What is throttle response?
A: When you step on the accelerator pedal or twist the throttle on a
motorcycle you can instantly feel the engine come alive with more
power. This is what we mean by better throttle response.
Q: The PowerSTAR changes the sound from my motorcycle, why?
A: The sound that you hear is a deeper sound cause by the
simultaneous ignition of the multiple points. The explosion in the
combustion chamber is bigger using more pressure.
For fuel injected Harley-Davidson motorcycles you get a deeper
throaty sound closer to the sound you got from your old carburetor.
Q: Will the installation of a PowerSTAR spark plug affect my warranty on my vehicle?
A: NO. In 1975 the Magnuson Moss Act was passed and it prevents a
manufacturer from voiding a warranty based on a customer's selection of
parts that the dealer or manufacturer does not offer. As long as you
follow our installation instructions and those of the engine
manufacturer the use of our product won’t void your vehicle warrantee.
Q: What modifications do I need to make to my engine to use a PowerSTAR spark plug?
A: No modifications need to be made as long as you have electronic
fuel injection in your vehicle. Since most of today’s car and
motorcycles have fuel injection the only thing you have to do is make
sure that you reset the engine control management system or ECM. This is
easy to do just by disconnecting the positive battery terminal
connection prior to starting up the engine after replacement. Please
consult our insulation instructions. To get more performance out of your
PowerSTAR spark plugs or if you have a carbureted engine please read
our installation guide.
Q: What is the “Green Effect”?
A: The Green Effect is helping the environment by curbing emissions that contribute to global warming and smog.
Every engine today has oxygen sensors that help the ECM fine turn
the engine. The Oxygen sensors monitor the amount of oxygen in the
exhaust both before and after the catalytic converter. A more complete
burn of the air/fuel mixture reduces the amount of unburned
Hydrocarbons, Carbon Monoxide, and Oxides of Nitrogen (NOx). PowerSTAR
spark plugs burn more of the fuel that would be sent out the exhaust
pipe that contributes to smog. The PowerSTAR spark plugs help you get
better fuel economy, which means less fuel is burned. Also your
catalytic converter doesn’t have to work as hard.
Q: What is smog, and how do PowerSTAR spark plugs help reduce it?
A: Motor vehicles generate three major pollutants, nitrogen oxides,
hydrocarbons, and carbon monoxide. Hydrocarbons react with nitrogen
oxides in the presence of sunlight and elevated temperatures to form
ground level ozone. This is called smog.
It can cause eye irritation, coughing, wheezing, and shortness of
breath. This can lead to permanent lung damage. Nitrogen oxides
contribute to acid rain, and to water quality problems. Carbon monoxide
is a colorless, odorless, deadly gas. It reduces the flow of oxygen to
the bloodstream, and can impair mental functions and visual perception.
In urban areas emissions from vehicles are responsible for more than 90
percent of carbon monoxide in the air. Motor vehicles also emit large
amounts of carbon dioxide, which has potential to trap the Earth’s heat
and cause global warming. By using PowerSTAR spark plugs you cut the
amount of fuel burned from getting form point A to point B. This helps
to reduce the amount of carbon dioxide you vehicle emits and minimizes
global warming.
Q: How does the PowerSTAR spark plug work?
A: This is what is happening inside your combustion chamber. Due to
the high intensity of the electric field created by the ignition coil
we have strong lines of flux coming off the tip and curving around the
cap toward the STAR points. This also creates a corona effect which, can
ionize the oxygen between the gaps. This creates hot spots at the
tips. Hot spots in a combustion chamber are good if they are
controllable. As the tips heat up electrons will be emitted where the
field strength is the greatest. The amount of heat that is created at
the tips is enough to cause a combustion event at the same time that the
spark jumps the gap with the highest energy level and smallest path to
ground. Our plugs are designed with tight tolerances between the gaps.
The difference between the gaps will actually even out as the spark plug
is “broken in” .
Q: How long do the PowerSTAR Spark Plugs last?
A: While we have multiple simultaneous ignition events, we only
have one spark jumping the gap and eroding the metal. Our star is made
with a high strength Nickel-Cobalt alloy (similar to the metal used in
nuclear reactor chambers). The alloy is stronger than the typical Nickel
used in center electrodes. Our spark plugs will last 5 to 8 times as
long (depending on the number of tips) as a conventional Ni center
electrode. For the standard Nickel tip spark plugs the average
replacement interval is about 30,000-45,000 miles. You were pushing it
if you put 30,000 miles on set. Your car would still work but your
performance will be degraded, and if it was wintertime you most likely
had problems starting your engine. The Platinum and Iridium plugs claim
80,000 – 100,000 miles. The wear curve is much longer. You actually
could have a poor performance lasting much longer and not notice the
degradation due to the longer period of time. You know the feeling you
get when you feel that your car isn’t working like it did yesterday? We
offer our guarantee with our spark plugs. For Automobiles we offer a
3-year/ 50,000 miles (2 year/ 20,000 for motorcycles) guarantee with
free replacement. We also offer a 30-day satisfaction guarantee.
