They don't like +4's or anything special from Bosch. If going Bosch use an OEM replacement, not a +4 or something "special."

. You guys are funny.
Bosch plus 4 plugs are the oem reacement plug. If you go have your plugs changed at the dealer, you will get, bosch plus 4 plugs installed. Not saying one is better than the other, but if somebody ask what the OE replacement is, don't tell them what you prefer.
