I am buying new sparkplugs for my 2006 Volkswagen Passat 2.0T and i purchased pulstar be1h10 sparkplugs with a plasma core, but i am now being told that they are not good for my car because they arent iridium but they are made of an inconel super alloy. I did a bit of research and a majority of what i found is that inconel is actually a very strong and durable precious metal. I am wanting to know if i should use the pulstar spark plugs or if i should return them and buy iridium spark plugs. My other research also shows that pulstar spark plugs are actually really high quality. So what im wanting to know is if i should use the pulstar spark plugs or buy iridium sparkplugs. Would anything happen to my car if i do not use iridium sparkplugs?
There are two significant design differences between these plugs.
One: The Pulstar plug has a much wider center electrode than a typical iridium plug. A thinner electrode allows better spark plasma to fuel mixture exposure. This results in faster ignition and less misfire.
Second is metalurgy; Iridium melts at over 4000 deg F while Inconel melts at around 2500 deg F. The higher melting point of Iridium allows the finer wire electrode which in turn results in the benefits to ignition noted above.
