Installation Guide
(LSG Brisk Halo Spark Plugs)

This Installation Guide for LSG Brisk Halo Spark Plugs is a general overview that provides basic insights and is not to be substituted for the expert advice of a qualified automotive mechanic.

NOTE: If the vehicle’s Check Engine Light is on you should have the problem fixed before the LSG Brisk Halo Plugs are fitted.

Stage 1: Make sure that you have the correct type of spark plugs for the engine.

Stage 2: Disconnect both battery wires.

Note: Do not work on hot or warm engines (it can cause damage to you or the engine).

Stage 3: Identify/mark the spark plug cables to insure that you correctly reconnected them.

Stage 4: Carefully remove the spark plug cables, check them for damage, and replace if necessary.

Stage 5: Remove the spark plugs using the correct tools.

Stage 6: If the spark plugs require an external washer (not applicable for taper seat spark plugs), check that there are no washer’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 required 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 spark 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.

SPARK PLUG		HEAD ON ENGINE
THREAD		Fe (Iron)	Al (Aluminum)
M 10 x 1	Gasket	10 - 15 Nm	10 - 15 Nm
		7 - 11 lb.ft.	7 - 11 lb.ft.
M 12 x 1.25	Gasket	15 - 20 Nm	15 - 20 Nm
		11 - 15 lb.ft.	11 - 15 lb.ft.
M 14 x 1.25	Gasket	20 - 40 Nm	20 - 30 Nm
		15 - 30 lb.ft.	15 - 22 lb.ft.
M 14 x 1.25	Tapered	10 - 20 Nm	10 - 20 Nm
		7 - 15 lb.ft.	7 - 15 lb.ft.
M 18 x 1.5	Tapered	20 - 30 Nm	20 - 30 Nm
		15 - 22 lb.ft.	15 - 22 lb.ft.

Note: Do not remove or install plugs by gripping the insulator with any tool.

Stage 10: Apply dielectric grease to each electrode tip before reconnecting the spark plug cables.

Note: This 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.
