I put the Berus in and am pleased, more of a difference than my other experiences with new plugs. The Bosch Platinums are frowned upon at...my Bosch Service Center!(they're not for turbos anyway) For $.99ea the Supers will provide a good bang for the buck. (pun intended) Some dielectric grease on all the plug contacts will liven things up as well.

HP at the bottom end and the same at the top end. The HP difference gradually came back to the standard plugs as the rpm's went up. If I remember correctly, the torque was the same, but with a greater improvement.

I got mine at Mach V automotive, good quick service.
