Any opinion on the BOSCH Platinum +4 Spark Plugs? Please advice.

It's my opinion is that they are in fact, made by Bosch.

They look nice and are color cordinated with Pewter....

on the serious note, I ran the plats in my bmw and I like them. Have no idea on running them in the H2

They make the 4.3L Vortec very unhappy and cause it to fail smog testing.
