I wish I had one

just took out the plugs and they were kind of whitish more than brown, but this might be normal for fuel injected engines, but I don't think is normal the code on the plugs itself BKR7EIX.
I'm running the NGK BKR7EIX which I think are not the right ones for my 1.4 boxer. The ''7'' stands for the heat rating right? Boxers need a 6 heat rating right, so I'm running the 7 (1 step colder)...!
So apart the gap that might have increase by using the plugs for about 45000 km, also the plug itself is not the right one for my engine.
Could all this lead to detonation or pinging at high revs??????
I have a feeling that this might have been the detail that made the difference in my car.
OOO SH*T...THIS IS MY 4TH ONE
