Spark plug “Indexing”?


Spark plug “Indexing”?

Spark Plug IndexingIf your engine has Direct Injection (DI) you should absolutely be having “Factory” original equipment spark plugs being installed at their recommended intervals.

Why? – Aftermarket and or “OEM” plugs are not manufactured to the precise specifications as the “factory original equipment” are.

To avoid piston damage the ground tab’s opening (of the plug) has to be facing directly at the injector nozzle (indexing) after torquing plug to factory specs.

There are technical bulletins published showing melted holes in the pistons and stating not their fault – should be using their parts!
