<<Please correct me if I'm wrong, but I've been getting the vibe that the BOSCH
Platinum +4s do not work with our engines. (5.2L)>>
Coming from me it's no vibe... Based on my experience with the +4's, I'd say
steer clear of these plugs --plain and simple! To be fair there are a couple of
guys running them and they have not experienced any problem with them yet. My
experience with these plugs was nearly catastrophic for my engine!
Both Bob DeChance and I are in contact with Bosch to try and get an explanation
for the poor performance of these plugs in my vehicle... We will let everyone
know if we find anything out.
