2. A spark plug is an
electrical device that sits
at the top of the cylinder
head.

the compressed air-fuel
mixture within the
combustion chamber.

in the centre electrode,
spark plugs are of the
following types:-
Iridium spark plugs
Copper spark plugs
Silver spark plugs
Single platinum spark plugs
Double platinum spark
plugs

5. A spark plug has an expiry
date, regardless of its
building material.

6. Typically, it lasts for
20,000 to 30,000 miles
or 2 years.

plugs in your BMW X5.

8. Signs of bad spark
plugs in BMW X5

9. Hard Starting Engine

10. Trouble starting the
engine is an obvious
symptom of bad spark
plugs in your BMW X5.

11. A spark plug is supposed
to set ablaze the air-fuel
mixture to start the
ignition process.

12. However, faulty spark
plugs fail to do so and
thus make it difficult to
start the engine.

13. Engine Misfire

14. Following factors are
primarily responsible
for engine misfire in a
car:-
Imbalanced air-fuel ratio
Unstable compression
Faulty spark plugs

15. Bad spark plugs not only
cause engine misfire but
also makes the engine
stall frequently.

16. Poor Acceleration

17. When you press the
gas pedal, your BMW
X5 is supposed to
accelerate.

18. However, incomplete
combustion due to bad
spark plugs can cause
sluggish acceleration in
your car.

19. Imbalanced air-fuel
ratio and vacuum leak
can also make the
engine hesitate to
accelerate.

20. Bad Gas Mileage

21. Worried about bad gas
mileage?

spark plugs are
working or not.

23. If the spark plugs are
worn-out, install new
ones.

25. It doesn’t necessarily
mean that your car has
some serious problems.

procedure, the dentist or
hygienist will inject you with
an anesthetic for numbing
purposes.

27. It could simply mean
that your spark plugs
are worn out.

28. So, get the faulty ones
replaced.
