What type of NGK plug

[k7lsy]

Hi there,

I've tried using the search facility using "NGK" over last 8 years and nothing comes up, and I know there has been threads on NGK plugs!!!

I want to treat my 3R to some nice new NGK plugs.

Can anyone recommend a set they have used successfully?

Let me know
Kind regards
Kenny

Leave the gap as already set (about 25 thou)

I think the gap should be 35 thou if i remember correctly! (Well, this is what mine are set at)

Rob - thanks for the suggestion.

That plug is made of copper - i'd thought with the heat generated by the Noble engine + turbo's etc would require a Platium or Iridium based plug.

Anyone got a suggestion for an Iridium based plug as an alternative to the std. Noble plug?

Let me know,
Kind regards

As long as the heat range of the plug is correct, its material should not matter. As a rule, "hot" engines require "cold" plugs.
The only reason to use plugs made of exotic materials, IMO, is if you want to leave them in for 100K miles.

+1 NGK BR7EFS is a 'cold' plug. And to answer Twerlies question, yes, 25 thou is correct for this plug (it's not standard)

Hi guys,
Thanks for all the replies - i'll go with the NGK and 25/1000 gap.

Cheers
