Sorry, I should have been clear. The long ones are the ones removed from one side the short ones are the correct size replacement. I went for bosh but should have just gone for the specified NGK. I agree someone put gt plugs in. The plug lead has degraded and the extra length made removal hard.

So I changed my spark plugs as the engine was hesitating sometimes at idle. I found these long sparkplugs. I think there was a bit of carbon on them. Hopefully it cleans up. I was surprised it ran so well. I've put many miles on it. I also changed the coil pack and lead. I think the lead were the actually issue as two broke during removal.
