Product Information

Manufacturers don't seem to want us to be included in the ownership process; there seems to be a 'dark veil' surrounding the act of questioning their decisions: ...'filled for life'...'they all run hot'...'they all need premium plus fuel'...'manufacturer fluids only'...with dire consequences of warranty violation.

Do not make spark plug changes at the same time as another engine modification such as different injectors/timing changes different boost loadings from your chosen forced induction, as in the event of poor results, it can lead to misleading and inaccurate conclusions, an exception would be when the alternate plugs came as part of a single precalibrated upgrade kit. When making spark plug heat range changes, it is better to err on the side of too cold a plug. The worst thing that can happen from too cold a plug is a fouled spark plug, too hot a spark plug can cause severe engine damage!
