Bosch +4 Spark plugs worth it?

I am running them, and I'm not very happy with them. Many people on this board will tell you the same. It seems that they are better suited for German cars.

I'd stick with just NGKs, or if you're feeling good, but some iridiums. I just got some, but I haven't had a chance to put them in yet.

I'm running regular Bosch Platinums and my comments are exactly the same as above.

The funny thing is, I've used them for years in other vehicles and they worked great; 80-100k before replacing. The counter-man at Auto Zone told me that Bosch Platinums are a hit-'n-miss proposition. Some cars they work great in, others [like certain Fords, he said] won't run at all with them.

Stick with the NGK V-Power coppers. That's what I'm going back to. They only last about 15-20k [in my HX] but they are a much, much better performing plug, and cheaper...
