Remove your K&N rock filter and hold it up to the sun, trying to use it as a shade. See all those points of light? That's where dust comes through, and that dust is not good for anything in your engine.
I am of course assuming you're using a reusable oiled rock filter.

That said, I currently have a Hengst engine air filter in mine that I bought NIB from LILBENZ230 after he sold his car. I have no opinion about it so far. But it will be better than K&N.
I used a K&N (once) in an '85 Nissan 300ZX. Hardly worth all the work, as it was a PITA to maintain.

I am not a **** for OEM parts, except for filters. You can't go wrong with OEM filters. I use MB OEM oil filters exclusively.
That said, I currently have a Hengst engine air filter in mine that I bought NIB from LILBENZ230 after he sold his car. I have no opinion about it so far. But it will be better than K&N.

I'm not at all sure why you would buy this when the factory air filter is at least $20 less (IIRC).
IMO, you should not worry about finding more air flow. The OEM filters offers airflow characteristics tuned for the engine, along with supreme protection. There is no Rocket Science in this.

I had a '96 Chevy truck 6.5 diesel that I bought used with a K&N. Every time I cleaned the filter, I also had to clean the fine dust out of the intake pipe - on the FILTERED AIR side of the filter. That was more than enough to convince me to go back to stock.

I like the sound of my engine too. That's why I won't use a K&N anymore; I'd like to hear the same engine in 100k miles...

Id rather have a good filter that keeps my engine clean than a few more ponies...

I am not even sure that most of K&N installation deliver few more ponies.
When they call themselves often "cold air" filters, most application makes them hot air filter, who sucks hot/dirty air from engine compartment, when factory filters suck clean air behind front grille.
How engine bay dirt can affect the air, I just discovered on my 1922 Ford T.
Originally the T never had air filter, what was not acceptable to me, so I added filter to factory design. It is 6" round filter as that was the biggest size that would fit.,
So put it on last year and I drove the car for about 60 miles since. Than lately the engine would start and die after couple of seconds. Spend over 2 hr checking fuel, carburetor. plugs, only to discover that the air filter got clog after 60 miles of driving.
The T is a dripper since some seals are made with felt and there is no way to stop oil drips on it and evidently that, with desert dust affected the filter placed at the rear of engine.
Now I have 5 spare filters in my garage.

There is a train of thought that superior air filtration is the most important factor in protecting an engine, even to the point that if air filtration is good enough, that oil filtration is of little or no importance. The best oil filtration can never make up for poor air filtration.
About 18 ago I put a K&N air filter in an Alero. I thought I could tell an immediate increase in power. But after inspecting the filter when cleaning and oiling it, I became very concerned about the size of the holes that I could see light through. After pondering the size of dust, and even sand particles that could pass through the K&N filter, I threw it away and replaced it with a traditional filter. It made me angry at myself, and even more so at K&N, for being duped into believing that they were offering a superior product.
