Just thought I'd let you know that halfords have knocked £25 off their stock of colour tunes making them only £10.I know you can slag me off & all that bs.but some of you might be interested.

What's a colour tune?

A colour tune is a spark plug with a visible chamber which enables you to see the colour of the combustion flame,so you can if required adjust the fuel/air mixture setting.get the right coloured flame (bunson blue).you then know your engine is running at its best (not running rich/lean).sometimes can work better than just going by the factory settings. You might have an underlying problem that you can't see.go to the gunson website and READ or better still watch the video.

Good bit of kit, makes life much easier.

Well spotted.
