Wow those are some huge drilled out air holes
Out of interest is the bore of the Center Post larger then the stock kayfun, as I found that's the bottle neck regards airflow, and making the air intake holes larger then the Center Posts bore makes little difference (not measured the original, but I drill it out to 5/64"/2mm) but guess these huge holes are more for cooling more then airflow????.
Not being very technical I can't comment on the bore size not measured but plenty of room. I can comment on the massive airflow. Yes it adds to the cooling as much as flow (lung hit champ). And to top it off great flavour. That was my one concern was that they might have sacrificed the flavour but in my opinion built right it's a great all round performer for the price.
