These seem too cheap

Seems cheap for the 4 tip kind, aren't they silly more like £10 each.
A ECP shed its load near there recently?
 
I seem to recall that NGK are better suited for some reason. May be wrong. They look like a well discounted item Sean, genuine Bosch plugs at a good price.

Sean they are a good price but they are bosch super 4 not the really dear iridium plugs.
If you look at the pictures the center pin is quite tall
I know these plugs are a bit dirty but the iridium plug just has a small central tip

The thing is guys that they will be changed very regularly, probably every year which means about 6k miles
 
Sean i don't know if the 6 cyl uses tbe iridium plug certainly the m43 does with extended range
The bosch super 4 should perform better than the twin electrode plug and well better than the single
 
Hi Sean, if they're recommended for your Z and they're Bosch can't see a problem. Maybe on the cheap side for Bosch plugs but then they could be old stock, IMO don't make em naff cos 10yrs ago they might have been top notch for your Z. Can't see inside the engine to know just how good they work and the makers wouldn't necessarily tell us they are as good as their latest offering, so the balls in your court. I have just a few weeks ago bought similar plugs for my 2.8 ( £30) and wouldn't have hesitated buying them for mine had they been the recommended type. At this price you could change them every oil change, that's got to be good for the ign/system.:thumbsup:

Roy.:happy:
