Time for a tune up / valve adjustment, wondering what spark plugs everyone is using these days.
My 70 914-6 was upgraded to 911S specs (2.2 or 2.4 liter, sheesh bad memory...) Stock ignition, still has Marelli Distributor. Currently running NGK B7EV, in the past had Bosch W225 T35. Not wanting to start an 'Oil discussion', LOL, but curious if there have been updates / changes. |

When i tried to get new plugs late last year I found out NGK have actually discontinued BP6ES 7333. Their site recommends BPR6ES 7131 as a direct replacement, but I was told the resistor in them didn't play well with the 123 distributor so I ended up getting BP5ES 7832 instead.

This is from the NGK site. For racing in my 3.4 L twin plug I used these: NGK BPR7ES (5534 large 13/16 base), or BKR7E (4644 small 5/8 base) I mention this because I researched small base plugs with all other parameters equivalent to the large base ones. It always was difficult servicing the lower plugs if I didn't remove the exhaust manifolds due to clearance issues . The small base plugs gave me just enough extra room that the job was easier. One or two heat ranges hotter would be proper for a street engine. I used small base plugs when I had a 944 Turbo for the same reason. Try the small base equivalent plugs in your preferred brand, I think you'll like the change. |
