Honda manual is made by honda atlas Pakistan. Whole world including our neighbour India (with same conditions as us) have moved on to modern more reasonable 10k oil change and 20k air filter intervals. Pakistani car companies like using the old standards meant for 1980s cars so they can mint even more money from the customers.
I personally only follow the manual till warranty expires and then move on to 10k km/1 year oil interval and 30k km/3 years for air filters. None of my cars ever gave an engine issue and my last car went up to 225k Kms and felt like it'll last for 200k Kms more.
Also I've went up to 35k Kms with genuine air filters and no performance or efficiency loss was ever felt, showing that it wasn't even close to being choked and replacement filter lead to no difference. I also don't clean out the air filters and never let anyone take it out of the air box cause that ruins the filter.
