NOTICE: Pulstar® spark plugs are not pre-gapped for your vehicle.

Set the plugs’ gap to your manufacturer‘s specifications.

GAP CAUTION: Do not apply pressure to the center electrode. Do not drop. Use vehicle manufacturer’s gap recommendation; not to exceed 0.055″ (1.4 mm). For factory turbocharged or supercharged vehicles, do not exceed a gap of 0 .025″ (0.64 mm). For all non-factory applications call 1-888-800-6700.


Disconnect the negative battery lead before installation to reset the computer on pre-ODB II vehicles (1996 or older).


Apply anti-seize to the spark plug threads and dielectric grease to the inside of the coil/plug wire boot prior to installation.


Start plug installation using a 3/8” diameter hose or spark plug install tool. Tighten to factory recommended torque using a deep socket (most models require 5/8″).

NOTICE: If present, remove spark plug insert from socket.

Typical computer-controlled vehicles may need to use up to one tank of gas before the benefits of Pulstar® spark plugs can be seen. To see benefits sooner, disconnect the negative battery terminal during installation.
