Hi mate I got the ngk's from halfords today, just took the 071's with me to compare the length. I actually fitted the same plugs to my other saph about a year ago and there still good. I've tried uploading a pic of the packet to photobucket but it's not loading.

Look for black writing up the top right hand corner of the packet saying BCPR6ES. With the trade card I think I was something like £9.

I got my 071's from Matt Lewis so going to contact them to send them back or even get the £12 I paid off of there sensor kit I want to buy.

Good luck with yours bud!
