Hi. Yes if it works for Joomla! articles it can also work for K2 items. You just need to modify the query so it updates the K2 items table. In general, hits are there to provide a general image of the item popularity, not to provide accurate statistics. For such usage you are suggested to use a tool like Google Analytics.

I try with K2 tools custum code. Put this code in module, set module to desidered position, excluded this position from caching, but no result. Hit are not increased by +1
Is code good. I have latest K2 and latest joomla 3.3
