They are not all the same

There is a difference between males of spark plugs. My bike (Kawasaki) runs better, ticks over better, and stays cleaner. Why, I don't know, but they do. Bought from Sportsbikeshop on-line for half the price of the leading car superstore. Delivery was the next day plus they sent a text stating what time to an hour - delivery was on time and well packed. Thoroughly recommend Sportsbikeshop - easy to use website - excellent all round.

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.

Luckily undamaged

Nothing wrong with the spark plugs but when I ordered it said they were in stock but after ordering I was told there was a delay in the order because they were out of stock. When they arrived I found they had been thrown into the box loose with chain and sprockets and one of the spark plugs had come out of its packaging and was rattling around the box, luckily undamaged.
