I've just had some Trust/NGK 7's fitted to my dc5, bought from Unit8, and the plug gap was at 0.75mm when they went in. It might be just me but it now seems theres a tiny flat spot at around 4k and then just about 6k, after the changeover. would opening the gap up to say 0.8mm (as recommended by Spoon) help?
