Bosch +4's in MC motor
I have a set of the +4s in my 4kqt. These plugs run very well in it.
They felt better seat of the pants than any of the plugs i tried. I
tried a couple other plugs in it (at 15psi) and all started to have
rounded electrodes after 1000 miles, NGK 3 prong, single prong, and
bosch supers. The +4s didn't. These are the plugs i'm stickin with.
Regular bosch platinums are the only thing my dad could use in his
old jetta 1 with stage two
calloway kit. If he didnt use the platinums he'd have to change them
every 2000 miles. Nothing else would last.
Whats bad about regular platinums again? Are you saying you'd get a
set of champions or AC's
over platinums?!? What marketing image? I never saw an infomercial,
did you? Bosch would never put their name on garbage. Bosch doesnt
play.
Bosch tested the +4s in a bmw engine near rev limit for something
like a week straight to try to
detect a single misfire, they repeat this a bunch of times. Bosch
wouldn't release a crappy plug. Who else uses or has even heard of
ytrillium alloy?
