I bought a set of Volvo OEM plugs from my dealer. I went to change the old (and original?? - they are Volvo plugs too) ones. They only have one prong, whereas the replacement ones have three.

Is this right for a turbo??

(BTW, it's an 02 2.9L Turbo)

 

Those are Non-turbo plugs.

 

Tech,
Thanx. I kinda figured that. The package says 2.9L exl. Turbo B280.

I didn't know what "exl." meant, but usually thought "excluding" was abbreviated "excl." not "exl."

 

Correct the turbo plugs are platinums.
The non-turbo are the 3 prong.
