Decent grade 7 spark plugs cant find a definitive answer with the search

[TubbyTwo]

Hi all

going to change the spark plugs this weekend, as will all my cars that run more than stock boost i stick a colder grade plug in.

I'm reading on here that alot of people use NGK BKR7E plugs which are coppers. Used these all the time on the MR2 turbo but just want to double double double check they are fine to use with the LCR.

Failing that any other recommendations for grade 7 NGK plugs?

have just read through the search results but cant find part numbers aside from Denso's (have had a bad experience in the past so wont use again.)

cheers

NGK BKR7E

these will do fine mate, just make sure they are gapped properly.

They ok to use on a LC as well?

 

[james walker]

yep... good plugs, id stay away from the iridium tipped plugs, they have been known to snap the tips off= poo pants time

 

[TubbyTwo]

Thanks James

Hi just been looking at spark plugs on sparkplugs.co.uk and they do NGK BKR7E and BKR7E-11, which ones would be the best to go for?

got evidence of this or here say?

yeah, i thought the iridium ones were supposed to be superior and longer life?

Im using denso IK22 for about a year now - everything's fine

I've just ordered a bunch of NGK BKR7E(6097) from the UK and plan to gap them at 0.28

 

[ADAM_84]

So the spark plug discussion continues lol I'll stick with my Original ones for the time being whatever they are lol

did you not say something of the like bill?.....

I have the NGK Iridium ones..... still working after 2 years. Gonna get copper before this race season as Ive been told copper has even better conductivity.

did you not say something of the like bill?.....

Bill's comments were more focused at Denso plugs rather than iridiums from memory..

0.28? hmmm. Hope thats not 0.28mm.

And for mapped cars its should be 0.028" which is ~0.71mm.

BKR7E's are one grade colder than standar so will be fine for any car really. Standard gap is .032"/0.8mm you can gap them down if you want or throw them in as they are.

Change them at every oil change as theyre only about 12 quid delivered. Copper core plugs dont last as long as Ir or Pt plugs.

used the BKR7E NGKs on the MR2 and they were fine, local motor parts shop does them for about £2 a plug iirc.

as said change with the oil and they will be fine.

DO NGK do an 8grade plug for the LCR and does anyone use them?
ran them on my evo yet my LCR pretty much boosts to the same level as that did?

Yes, 0.028, minor details with the zero's and dots... lol

Just had them delivered (20 pcs), paid 1,82 £ each bought in the UK.

Is it worth gapping them that extra 0.1mm? (Running REVO stage 2 a 1.25 bar)

 

[TubbyTwo]

I was planning to run them at the standard gap unless its recommended otherwise??

So does anyone know if there is a difference between the NGK BKR7E and the ones with -11 on the end on camskill.co.uk
