Hey guys, hope everyone uk based is enjoying our little heat wave?

Today I put in a K&n filter and removed the snorkel, the filter was pushed home but the filter was sticking out a little, but once I nipped the cover screws up on the filter box everything seemed to seat properly, is this normal for these filters?

Also is there anything I can do on a 06 to reducing the popping?

Sorry forgot to say it's on a xtr.
