Product Installation
Users can view the Installation Instructions for LSG Halo Spark Pugs. However, these instructions are general overviews that provide basic insights and cannot be substituted for expert advice that a trained automobile technician can provide.
INSTALLATION GUIDE FOR LSG HALO SPARK PLUGS
Note: If the "Check Engine" light is on, then the problem must be fixed before the LSG Halo Plugs are fitted.
Stage 1
Before installation make sure you have the correct type of spark plugs for the engine being serviced.
Stage 2
Disconnect both battery wires. This will reset the Engine Control Unit (ECU) and adjust the spark ignition timing to match that of the Halo Spark Plug. If you have an older vehicle that does not have an ECU, then the ignition timing needs to be manually adjusted by a trained technician.
Note: Do not work on hot or warm engines as this can cause damage.
Stage 3
Identify the spark plug cables to insure the cables are reconnected correctly as covered in Stage 11.
Stage 4
Carefully remove the spark plug cables. Check the cables for damage and replace if necessary.
Stage 5
Remove the spark plugs using the correct tools.
Stage 6
If the plugs require an external gasket (not applicable for taper seat spark plugs), check that there are no gasket’s remaining on the cylinder head from the removed plugs.
Stage 7
Put a little bit of anti-seize compound on the front two threads of the new plugs before installation.
Note: Anti-seize is needed on aluminum heads to prevent electrolytic action between the steel spark plug body and aluminum head. Do not use too much anti-seize.
Stage 8
Install each plug until finger tight.
Note: Spark plugs that are not tight will run hot and can cause serious engine damage. If you cannot seat the spark plug all the way with your fingers, there is probably carbon in the threaded hole in the cylinder head. Chase the threads with a thread chaser before installing the spark plug. When removing plugs, examine the seat area closely for evidence that the plug was seated all the way in its previous installation. On plugs with gaskets, the gasket should be compressed. With tapered spark plugs, the seat area of the plug should show a “witness mark” (proving that it was seated). Spark plugs that fail because they were loose can have a blown out center electrode or insulator, or the outer shell can be blue.
Stage 9
Tighten the spark plugs to the recommended torque for the plugs and engine, by using a torque-wrench and sockets that correctly fit the hexagon of the spark plug metal shell. Table 1 below shows the correct torque settings.

Note: Do not remove or install plugs by gripping the insulator with any tool as this will damage the plug.
Stage 10
Apply dielectric grease to each electrode tip before reconnecting the spark plug cables.
Note: This operation will provide a good seal between the plug cable and the electrode tip.
Stage 11
Reconnect the spark plug cables to the correct plugs as marked during Stage 3.
Stage 12
Reconnect the battery cables.
IMPORTANT: Please check the thread length of the Halo Spark Plug and make sure it's the same as your original spark plugs before installation. The Halo may be slightly shorter in length and this is OK. If, however, the Halo is longer than your current plugs, you may have the incorrect part. If this is the case, do not install the new plug and contact Customer Service @ 214-504-1760.
