Are these any good?

I'm always wary of these ebay 'upgrades' they do..... I'd just stick to the branded ones we all use (BCRE8's or something?)

bcr8es are fine and cheap!

i wouldnt even entertain looking at them its not worth it when you can get a trusted brand for a little more money. NGK, DENSO, although ive had a few NGK plugs let me down. not just in the R but in some of my old cars & motox bikes when i raced them, but i stick with DENSO plugs now as ive never had a fault with them. but may try NGK bcr8es next as they seem to be favorate for the R.

And also if there made out of cheap metal which they will be as there cheap ebay jobs id always be worryed about the tip snapping off with the heat or something. then it is game over :doh:

I got these http://www.ebay.co.uk/itm/350470869099?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649

Im using Denso Iridium IK22 seem really good.

Hiya,

I know this is a daft question, however, ill ask anyway. what would be the effect of using 3 BCR8's and 1 Iridium at the same time..... as i needed a plug in a hurry.

cheers,

different heat ranges? one cylinder hotter or colder than others? det? backwash? at a guess..
