Oh, I think BKR7EIX's are supposed to be pretty sweet - cue more knowledgeable person to come along and correct me

I ran Bosch super 4's for a few days and the made my idle uneven $\:\($

Bosch FR6KT6 or NGK BKUR6ET are recommended in the FAQ section $\:D$

NGK every time

BKUR6ET for standard and lightly modded

BKUR7ET for up to about 300 - 330bhp

BKR7EIX for up to 375bhp

BKR8EIX for 400bhp +

All estimates and all IMHO

Ended up with the BKR7EIX wasn't planning on going over 350bhp so should be all good $\:\)$

Good choice steveo, how much did you pay in the end for them. I just got some for £32 delivered.

aj4151 is the user dude, not sure about cooler or what ever, guessing theyre cooler asmore power generally means needing cooler plugs right? or is it the other way round

Re: Good spark plugs? - 23/12/2008 18:36

yes, more power requires cooler running plugs (which is denoted by the higher number)

Got them in the post and they are BKR6EIX which are for the 20vt but are not listed above??? any ideasif they're good???

They're the iridium version of the 6ET's. Fine for a relatively standard car - if you're running more boost than standard, 7's are recommended.

Well its only running a gtec 1 so should be ok then.

Re: Good spark plugs? - 25/12/2008 11:18

Yes, that will be fine.

I know it's an old post, but I'd like to add NGK part numbers, sometimes search for BK*** codes doesn't yield results.

BKUR6ET - NGK Stock No: 6437, "Standard" range - copper plug, 3 electrodes
BKUR7ET - NGK Stock No: 7873, "Standard" range - copper plug, 3 electrodes
BKR7EIX - NGK Stock No: 2667, Iridium IX Range
BKR8EIX - NGK Stock No: 2668, Iridium IX Range

Are there any benefits or downsides on running colder (BKUR7ET) or colder Iridium (BKR7EIX) spark plugs on stock or nearly stock (eg. remap up to 1.2bar, without other mods) 20vT?
- lumpy idle?
- worse mpg and/or emissions test?
- longer lasting?

Any experience with NGK Platinum (roughly same price as Iridium)?
