electrical and ignition Spark Plug Options

[mlcrum]

I am replacing plugs in my 73 2002. The current plugs are Bosch W7DC. I heard that they are no longer available. The car has Weber DCOE 40s, electronic ignition and 292 cam. Any suggestions to what would be a good match for this set up. Thanks

BP6ES. I ran BP5ES's in the car when it burned oil. New motor will get 6's...

[Rocan]

agreed... if your car burns a lot of oil close the point gap up a bit or run the BP5ES to help with the residue. I would run a .45 plug gap with the megajolt and it would run much better, but as soon as the plugs got wet the motor would stumble and run like crap. I closed it up to .30 and had no issues.

BP6ES.

 

BPR6ES if you have spark noise in your radio,

along with the Marelli 1K rotor and cap.

 

Really.

is that cap and rotor suggestion for noise as well, or a good idea otherwise?

The Bosch plugs are still available, they have just been relabeled.

Look for:

S1 - same as WR7DC

S3 - same as WR8DC

 

Hope this helps. Beaner7102

It appears the W7DCs are still available however based on the feedback I chose to go with the NGK BP6ES. Purchased and installed them today. The gap setting out of the box was 0.034-0.035 according to my inexpensive gauges so I used them as is. As usual, the FAQ crowd was very helpful. Thanks.
