I have a 94 Max low class - i cant remember, eather GLE or GXE
I want to get a set of Bosche +4 Platinum plugs, they say Bosche garantees increased performance or they pay for the plugs.
Has any one tryed the +4's, are they really that great?
Should I get them?

It will seem like your VG is running good but you will soon see that its just because you have new spark plugs .I had them and they we ok for about 2 weeks after that I wish I had (and did ) put the NGK's back in even on our slower VG's the ngk's are the best way to go

Which NGK plug should I use than? standard, V-power, platinum(G-power or VX), or Iridium?
What will be second best if i don't want to spend way too much?
will the platinum +4's work alright if I don't want to spend too much?

dont get plat plugs...copper is better, and plat arent reccomended for the vg neway...i used +4's, no noticable diff, and some vq guys have horror stories about the +4 (prongs breaking off, etc) so i wouldnt use bosch at ne rate...just pay for for ngk and i would just go copper...cheaper, better conduction, just gotta change them more

ive never had any problems with +4's but NGK's have been better in the max. the one thing about the +4's is that it is pretty much all marketing. there is only one spark and one contact point, so no matter what it will only go to 1 of the 4 tips. id rather just have one tip, the setup is much better.

platinums are nice because they last alot longer, and have a much better spark, but dont use them unless your car asks for them.
a fun trick is to file down your copper plugs to a point then gap them, but they wont last very long, maybe 200 miles.
