Super spark plugs for CBR 600RR
These spark plugs are a perfect replacement for the stock spark plugs in the Honda CBR 600RR. The throttle response feels a little more punchy and the burn seems a little cleaner, though that may be because the plugs hadn't been replaced in 30,000 miles. One word of warning though, be prepared for a world of pain removing and replacing these in a CBR600RR 07. If you don't have the toolbag that came with the bike and the spark plug replacement tool be prepared to spend a lot of time on this. Removing the radiator gave me the space to fit a set of extension bars and a slim socket down into the engine just to get out the original spark plugs. As always from Sportsbikeshop, quick delivery and a good price.
