I think the bottom line is, if you're ride has insanely hard-to-change plugs then they're probably worth the difference. Otherwise, Iridiums are already good for 100K.
My thoughts exactly. I actually run NGK coppers in my 240 cos they are so easy to change. I slap new ones in every 2-3 years and never have an issue. They still look more or less fine when I pull them.
But yeah, if I had a subaru or H-something, you better believe I'd be putting in the longest lasting s*** I could find.
