Pontiac Spark Plug
Spark plugs are used on the fuel injected combustion engine to provide the spark
that is needed to ignite the starting system, and eventually set the engine in
operation. Typically, a Pontiac spark plug is composed of an outer covering, connecting
end, central part, central electrode, seat area, and ground electrodes. The traditional
spark plug uses steel or nickel electrodes while the newer design uses electrodes
that are made from expensive metals such as gold, platinum, and palladium alloy.
These precious metals have high resistance against corrosion, resist greater
fouling effect, and provide longer life than its predecessors. Most Pontiac vehicle
uses a single spark plug on each cylinder, but the newer model uses two plugs
in each cylinder. The main purpose of having a spark plug on your engine is to
ignite the air and fuel mixture inside the cylinder. A high voltage power from
the ignition coil triggers the Pontiac spark plug at a precise time. The result
is also a precise and even burning of the mixture that cause the engine to produce
the massive horsepower it can provide.
Your Pontiac spark plugs needs to be maintained regularly and must be replaced
in specified interval that ranges between 30,000 to 100,000 miles. The range all
depends on the power of the Pontiac vehicle and the type of spark plug being used.
There some signs that your Pontiac spark plugs need to be serviced and replaced
if needed. These signs may include increase in fuel consumption, failing on emission
tests, and poor acceleration. A bad spark plug can also cause uneven burning of
the mixture and misfiring. Neglecting this signs can cause serious and more expensive
damages to your engine and the exhaust system as well. Remember also to always
use the correct and specified Pontiac spark plug to your engine to prevent any
damages to occur.
