Ditto on the premium gas to improve engine idle vibration and a wee bit more oomph in the CVT models (at least until the gas tank gets down below the 1/3 of a tank mark).

...and, allow the engine to ingest a whole lotta crap. If you travel anywhere with airborne particulate, not necessarily visible, it'll get past the K&N and be ingested. Been there, done that. Whatever meager perceived gains are maybe realized, they'll be wiped out by a guaranteed cruddy intake system. K&N needs to include, at a minimum, MAF cleaner in their filter 'service' kit.

+1. Much like Ronzuki, I've had K&N and similar oiled fabric filters (both panel and cone type) in the past and won't touch them now. They simply let too many particles through... given they were designed to improve airflow at the cost of filtration quality. The thing about K&N that many people may not realize is that they got started focused on offroad racing applications. In this context, standard paper air filters got clogged with dirt too quickly and restricted airflow. The K&N filter was developed to keep air flowing past the dirt but at the cost of filtration quality. It made a lot of sense for offroad racing but not much for everyday driving, especially for vehicles that owners intended to last a long time. For longevity, you'll want better filtration to keep the combustion mixture cleaner. Not only that, unless you encounter a lot of dirt, the oil eventually gets sucked into the intake and gums up components like the MAF sensor as Ronzuki mentioned. Again, high dirt exposure is part of how K&N filters are supposed to work and for ordinary passenger cars, it's just not a practical reality.
Lastly, modern engines have optimized intake designs. Just look at the Kizashi's intake. It's an ideal OE intake design that combines cold air and short ram intake concepts into an OEM design. No longer are OE designs sucking in hot air from the engine compartment. It's drawing in colder, isolated air by means of a dedicated air intake behind the grill. It's another reason why I personally feel modifications to the intake and filter aren't necessary.

I am sure you are more experienced than me about Kizashi engine but these are my results so far:
my car has 124K on it I started to use K&N filter on 60K and so far average fuel consumption is around 8.5 L/100KM in city which is very good in my opinion. I am using SDT2 suzuki diag tool to monitor MAF sensor parameters since the beginning of installing K&N filter and so far no problem seen.
and in case of potent booster I simply can not drive without it

Just depends on how much particulate that's in the air. Entire intake system on the 'clean air' side of the drop-in K&N filter was a black, oily, cruddy mess. This was a 2000 318 V8 Dodge. Yeah, it's usually always dusty driving around farmland roads.

Not forgotten, simply unadvertised........

I found 2 videos on YouTube about air filter I find it interesting
1-
2-

at the end of video number 2 narrator talk about throttle response and how electronically driver can control it by using sport mode selector.

Today I cleaned my car throttle body and guess what it was disgusting, after 7 year (2 years with K&N filter) it really need cleaning here is some photos before and after cleaning
and after cleaning

Nice photos on the TB clean. It's been one thing I've neglected so this helps in reminding me to do it at the next service.

Thanks I am glad that helped. I decided to do that every 6 month to see how much dirt is added with and without K&N filter.
