84 3.2 plug recommendation stock street engine

[198491132]

Hello All....been awhile since I changed plugs, searched forum but no clear recommendations. I have used NGKs in the past, but now there are many options and ranges available. Car has 108k, stock, street only. Which plugs?

Thanks, Dave

Ngk BPR6ES

Use whatever the owners manual recommends. For an 86, it's WR7DC, Bosch copper. I would assume the 84 is the same, but check the manual.

Copper either NGK or Bosch

All manuals say Bosch WR7DC. I would like to use NGK, but can only find BPR6 ES. Is the heat range that much different, or are these two interchangeable?

Just have had great luck with NGK.

Thanks, Dave

Being German Bosch was factory on the cars but that doesn't mean they are the only, best choice. (The Bosch copper are not a bad choice in any way.)

The NGK BPR6ES is the first choice of a major portion of "those with an educated opinion" on the Carrera. It will be one more thing you don't have to think about on the car.
