Q: Why should I pay more for SplitFire Spark
Plugs?
A: The key reasons: SplitFire patented split 'V' ground
electrode helps deliver more complete combustion.
Result: Maximum percentage of fuel is converted to
combustion energy not partially burned exhaust, for
performance only SplitFire can deliver.
Q: Why does SplitFire offer a 30-Day Money-Back
Trial Period?
A: We want to remove any doubt whatsoever about how much
more SplitFire can do than conventional spark plugs. If,
within 30 days, you're not completely satisfied, just
return the SplitFire plugs -- and you'll get your money
back. Complete warranty details are available wherever
SplitFire Spark Plugs are sold.

Q: Why can't I split my own spark plugs?
A: There are several reasons for not trying this
yourself. First, splitting the ground electrode of many
spark plugs could cause the ground electrode to develop
large cracks that could lead to one "ear" of
the electrode falling off into the cylinder.
Second, the ground
electrode must be of the correct thickness. If the
ground electrode is too thin, then the two
"ears" would not transfer the proper amount of
heat away. This could result in the build up of enough
heat to cause the "ears" to be the source of
ignition of the air/fuel mixture and could cause major
damage to the engine.
Third, the split must be
cut at the proper angle and depth or else the spark plug
will not function as effectively as it should.
Fourth, if the split is
cut too far off center, then one of the "ears"
could be too thin to effectively transfer away heat. The
result could be the same pre-ignition danger noted
above.
Q: Will SplitFire Spark Plugs work with a
"high performance" ignition system?
A: Yes. SplitFire Spark Plugs will work with any type of
ignition system.

Q: How long will SplitFire Spark Plugs last?
A: SplitFire, Inc. guarantees that SplitFire Spark Plugs
will meet or exceed your automotive or truck
manufacturer's spark plug performance standards in a
properly tuned automobile or truck with a non-modified
engine for 36 months, regardless of mileage driven, or
we will replace the spark plugs. (See our Warranty
information sheet for full details of this limited
warranty.)
Q: I have made modifications to my engine. What
heat range plug should I use? How about a shorter or
longer reach spark plug?
A: There are so many different engine modification
possibilities that we are not able to tell you which
specific spark plug to use. Follow the plug
specifications recommended by your engine builder or
consult the component(s) supplier/manufacturer(s) for
their recommendations.

Q: Do I need to change my timing when I put
SplitFire Spark Plugs in my engine?
A: No. Use the factory specifications. If you have made
modifications to your engine, you should consult the
component manufacturer's specifications
Q: Are SplitFire Spark Plugs hotter than normal
plugs?
A: No. A SplitFire Spark Plug has an unblocked flame
kernel, not a hotter one.

Q: Are SplitFire Spark Plugs pre-gapped?
A: No. The plastic cap that is put on the end of
SplitFire Spark Plugs is there to protect the ground
electrode from getting damaged during shipping -- not to
keep a set gap. One SplitFire Spark Plug can fit various
engines with each requiring different gap settings.
To gap SplitFire Spark
Plugs, use a flat or round wire gauge. Don't use a
graduated scale gauge, they will result in one
"ear" of the ground electrode being lower that
the other one. Make sure the wire gauge is wide enough
to gap both "ears" of the SplitFire Spark
Plugs.
Q: Do I have to use SplitFire Dual-Mag Wire Sets
with SplitFire Spark Plugs together to have either
function properly?
A: While we recommend using these premium products
together, you may use them in combination with any other
spark plug or wire set.
