Take those back and get the Autolites!


Exactly.

Actually ALL of Bosch's plug are indentical in design. The only difference between them is the +2's have 2 ground electrodes (and cost 2 times the std) and the +4's have 4 ground electrodes (and cost 3 times the std) All plugs are considered single platinum!

There is no performance benefit of one over the other just a "theoretical" longevity aspect of having more ground electrodes to jump between as they wear out. The funny thing is the POS center electrode (another story in itself ) is only rated for ~40k miles so all the plugs will last the same length anyway.

It's 100% marketing BS!


Stick with the Autolite (APP764) or Motorcraft (AGSF32PPM) DP's and you are set.
