The iridiums will last longer and offer a real high powered spark with a lower temperature than the Bosch Plat 4's. The V-Power are basically what I sell to customers day in and day out that come in for NGK spark plugs. V-Power is basically the standard NGK plug, except it has a bit better design that allows quicker burning of the AF mix. You can read about the V-Power here and then click on the Standard, Platinum, and Iridium on the side to view the differences. The V-Power is somewhat like what would be OEM in our cars.

And the reason 95STHATCH got a noticeable difference, very very slightly nitceable mind you, is because as he stated...his Bosch plugs were OLD. Brand new the Bosch plugs should produce more or equal power compared with the V-Power one's brand new. But yet, the Bosch's wear much quicker and aren't meant for our cars. The standard way to find it goes like this...

Ford - Autolite spark plugs
GM - Champion
European (BMW, VW, etc.) - Bosch
Most Japanese Imports - NGK

These are typically that brands that come stock with the car from the factory, and always should be replaced with these unless the substitute is something better than doesn't run at a hotter temperature than the OEM ones. This is because after a certain temperature, the hotter the plug gets...it's eficiency decreases.

Hope this helps. Better have, cuz my work (NAPA) gave me 3 hours of pay to go to a 3 hour seminar on the ignition system.
