As far as the accuspark goes, you really quite simply can't beat it. I have had fitted a few now and for the money I was sceptical about there claims thinking it would be some cheap chinese knock off part like we are all used to thanks to the like of EMPI etc, but they really are good and they are one of the simplest things to fit as well. Get the vac advance one with the EE already in and the job is half done for you! It won't knock seconds off your 0-60 or enable you to do 50+mpg but it will work as intended and start on the button. Two thumbs up
I bought mine from here http://www.simonbbc.com/electronic-ignition-kits?zenid=bd03794a633147ceff8cd43fc8f51629
So are Accuspark and Powerspark the same? I was looking at this site to buy the Accuspark: http://www.accuspark.co.uk
I've tried to find out online if there's a difference and there's no difinitive answer. They may well be the same item but they do trade as different so I'm still on the wiser.
