K11 Spark Plug Gap

[IanClement]

Hi guys, just bought my first Nissan and it's a mint 1997 Micra Vibe with a 1 litre engine. Doing the usual checks when you first get a car and I've bought some Champion EON2 spark plugs from Halfords on recommendation of this site.

They seem to be gapped at about 0.9mm whereas my old plugs are a touch over 1mm. Haven't managed to get my hands on a Haynes manual yet and have found conflicting advice on the net and this forum so I thought I'd better make sure.

The car drives OK as it is but I found a table on one thread on here (can't find it now!) that suggested 0.8 - 0.9mm.

hi ian (Y) i doubt if .2mm will make sweet FA difference personally

Just realised I put this in the K10 forum.:doh:

Thanks for the reply Frank, I want to get it right for fuel economy but it's good to know I won't damage anything if I put them in as they are.

Just for reference, I went to my local garage and they looked in the book and quoted 1.1mm. Plugs are in and the car runs fine.

Haynes quotes 0.9mm IIRC

Thanks Collison.(Y)

Sorry to resurrect an old thread now, but I just got hold of a Haynes manual now and it says 1.1mm, not sure why there would be a difference between one book and another.

That was me quoting from memory! 1.1mm it is
