Scotty, What do think of Bosch Quadrupole Spark Plugs. Do they work better and longer than regular plugs?
Here's a great video by NGK explaining multi-ground spark plugs:
I see the idea behind it, but we've been using single-ground spark plugs for a very long time, and they work just fine. Honestly, I feel like it's more for bragging to your friends..."Hey I've got perfoemance multi-point spark plugs on my engine, I'm making more power than you!" No power differences whatsoever though.
My BMW is supposed to use their OEM three-ground spark plugs by Bosch, but I switched to NGK single-ground laser iridium plugs, and I've had zero issues. They even run colder than those OEM plugs too.
It is just a gimmick.
Definitely a gimmick the voltage is still the same going to the plug and it’ll still only spark to one point
