Spark Plug Q


Tones

Recommended Posts

Don't use Platinums...use coppers or iridiums.

 

BKR7E's gapped to 1.1mm should be spot on.

 

As said if you get -11 specced spark plugs they should be pregapped to 1.1mm - though it always pays to double check.

 

Alex, I believe he copied that from the Spark plug FAQ.

 

Edit: Which I see you've just updated to clarify ;)

NGK - BCPR6EP-11 - gap is already 1.1mm at the "-11" signifies they should be set to this already.

NGK - BKR6E (2756) - gap 1.1mm

NGK Iridium - BKR6EIX-11 (3764) - gap is already 1.1mm at the "-11" signifies they should be set to this already.

Denso Platinum - PK20R11 - gap 1.1mm

Denso Iridium - IK20 - leave gap alone

 

TT @ upto 1bar

NGK - BCPR7ES (3330) - gap 0.9mm

NGK - Iridium - BKR6EIX or BKR7EIX - leave gap alone

Denso Platinum - PK20R11 - gap 0.8mm

Hi, above is coppied and pasted from the FAQ from plug selection bit, I thought all these were recommended so yesterday I too went out and bought NGK BCPR6EP-11, got a good discount too(I think) as these were on the stock TT list above but now Supra_Dori has been told not to use these as they are platinum, is this correct and if so should they not be taken off the list? Also Supra_Dori was then recommended to use BKR7E's gapped to 1.1mm but again the above list in FAQ puts them in the non stock list and says gap them to 0.9mm.

 

Should I return mine and what is the best to use in a stock TT, between some threads and the FAQ it gets quite confusing!

 

Thanks in advance

Just been searching again and the more I read the more I get confused as to what to do, so many different recommendations and contradictions, as above should I keep the platinums or return them(are they that bad?), did see copper NGK BKR7E on a link for just over £10 but is the colder grade fine in a totally standard TT? Alex or anybody? Help please...
