Sorry but Spark plugs again

[Sukhdev Sandhu]

Hi, I want to fit new sparks, but there seems to be a plethora of differing views as to which is the best option in choosing the right spark plugs.
Oem, platinum, iridium, etc, etc then single, quad or twin ground.....
Which,which,which aaaahhhhh!!

No point in spending a fortune on long life plugs when we change them so often

Depends on what engine as well .
My M43 engine takes iridium plugs standard.
60 k change period but also about £65 a set.
My wife's m44 takes standard twin electrode plugs at less that £12 a set

Mine is the 2.5i N52 engine

I find that as long they are a well known make it doesn't make a lot of difference. Just as long as they are the size recommended. Put your number plate in Opie Oils website and it comes up with several options. In the past I spent a lot on new plugs but I think a lot of any difference I perceived was in my head. A mechanical placebo effect

Hi, I just bought plugs ILZFR6D11 Iridiums, Opie Oil tecnical department when contacted adviced that the gap is preset to 1.1mm.
I mentioned that my Bosch double platinum sparks were set at 1.00mm when I checked them. I was told to adjust them to the Z4 factory setting. If anyone have fitted the ILZFR6D11 to the N52 2.5i what gap did you set it at please.
Your quick response would be appreciated, before the plugs arrive.
