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.
Inconel , AKA nichrome and a few other very similar alloys, are what plugs have always been made of ( at least since the 50's). I have removed 16 manufacturers original platinum plugs with 100,000 miles . All looked perfect , I hated to throw them away . New replacement platinum plugs made no difference in performance or mileage. I don't know why one would need better than 100,000 miles of excellent performance.
