Oh, they're definitely more efficient -- at pulling money out of your wallet when you buy them. There's nothing new or groundbreaking about them, and the maker's claim that "the spark plug hasn't changed since 1904" is idiotic. I had to give them credit for at least having some valid science on their site. I called them up -- it was almost impossible to find their phone number; they've worked very hard to keep it hidden. It was nowhere on their site, and they deliberately left it off their domain registration's whois info. I did find it, though, and spoke to the guy who answered the phone. He claims the plug was designed by Champion's retired head spark plug engineer from the 1960s, who oversees production of the plugs...in China...by a subcontractor of a subcontractor. Whee, are we havin' fun yet? :roll: It's all marketeering, no substance. All sizzle, no steak. All hat, no cowboy. All litterbox, no cat.
Gimmicky spark plug scams are nothing new. Back in the days of gas price wars that started at 29¢/gallon and went downward from there, JC Witless had full-page ads hollering RUN YOUR CAR WITHOUT SPARK PLUGS! Back then they called 'em "fire injectors" rather than "E3" or "pulse plugs", but the claims, hype, handwaving and pseudoscience were just about the same.
Buy a quality spark plug of the correct heat range. That's all you have to do. Everyone's got his own preferences in brand; from where I sit Champion is cheaply-made Junk and Autolite is, too, now that they're made in China. I've never liked Bosch, but NGK has always sold me consistently well-made, good-working spark plugs so that's what I use.
