NGK Iridiums BKR8EIX ***12k mile update on page 13***
sub39h:
it fires up right away, even from cold
gigolo456:
Hmmm, mine did on 6's, maybe I should revert back!?
56OctyVRS:
Perhaps when installing one of the plugs they damaged an electrode, which is why it is not running correctly. I found my car ran better with the 7s than 6s. I tried the 8s for a while but they started to foul so I switched back the 7s and all was good again. If you have your old plugs I would refit them and see if the problem goes away.
sub39h:
Just a quick update on this - I've got an unmapped K03 and i still haven't had any issues with this plug. done over 12k miles on them now. varied driving conditions, but limited spirited driving due to not being able to afford petrol and mainly motorway miles.
i had a single incidence of a misfire whilst sat in traffic a couple of months ago but has not repeated itself since. no fault codes. no problems with cold starting.
TT-Turbo:
I had my BKR8EIX plugs in for a similar mileage on my K03 also, they seemed to work well and have had no misfires but when I checked them recently I found this-
They were massively coke'd up and had loads of carbon deposits. I changed back to the hotter "7" plug and since the engine actually feels like it's got quicker which may have over the last 600 miles burnt off excessive carbon deposits. Worth thinking about, they may not be any noticeable running issues but since changing back the engine seems stronger.
