Since refitting the 7s my mpg has gone back upto 37ish on a run. I could barely get above 30mpg with the 8s fitted on a run. The engine is running smoother now and seems to pull better. I think for normal driving the 8s are probably a bit too cold. When I removed them they were fouled so they werent getting hot enough to burn of the carbon deposits.

NGK Iridiums BKR8EIX

I fitted these Iridium 7s about 10 days ago, after having Platinum 6's for the previous 16 mths. To be honest, i'm not sure if i will stick with the 7s!? Maybe it's just me, but i've found it takes 2 or 3 turns to start in the morning now; with the 6's it started 1st time hail, rain or snow! This morning (last used on Saturday) it took about 3 turns AND started quite gingerly, does anybody else have this?? It just seems ironic that all this started IMMEDIATELY after upping to the 7's...... :sad1:

Out of interest, how old is your battery?

I know there meant to be pre-gapped, but did you check the gap was correct before install?

had them fitted by an independent VW, etc Specialist and as far as i know, they were 'gapped' at the standard 0.8mm, which apparently is supposed to cover 99.99% of situations. Wondering though, although wouldn't even know how, if i should change the gap!!??  :confused:

....If they work, don't mend them! I don't think that changing the gap should be done unless by an expert with the right tools. If the gap is not what it's supposed to be, then wouldn't you feel that something is wrong and needs mending?

cheers Freedy, yes, if i leave the car for more than 24hrs, it's slow in starting, totally different to how it was with the Platinum 6's. I wonder if it's got anything to do with the fact that the car had a custom map 5 wks ago whilst the 6's were still in!? Just seems a huge coincidence in my eyes anyway that i've only had starting problems since upgrading to the 7's...  :sad1:

I had them fitted by a very reputable independent specialist in S. Yorkshire, so can't imagine they weren't fitted correctly and/or tightly, although i wouldn't have a clue how to check tbh!!?? Ref the battery, how does one check the life left in one of these??  :rolleye:

Do you have a multimeter to check voltage?
If not somewhere like Halfords can check it for you.
