I switched out my Plus 4's last spring when doing my headgaskets and lost the excellent low end torgue by going the the new Bosh Fusion.
I didn't loose any mileage, just low end, hence I alway recommend the Plus 4's to everybody that asks me.

 

WTF? Nice comment, man

Definitely not operator error. I change my plugs one at a time so there is no chance of mixing the wires. It's the plugs. Changed back to the +4's and problem solved.

Thanks for the help, guys!
