Because I spend most of my driving time in traffic And don't get on the highway all that much I've been thinking about a performance air filter instead of all new intake. So am I crazy...
Performance air filter versus new intake

I get a slight whoosh sound at higher rpms just before a gear change with my K&N panel.

I have the intake from RRM and love the difference in both performance and sound FWIW

Have had my drop in for just one month.. It does make a different kind of noise, it does increase my fuel mpg, and it does increase my HP. I heard it from a company that makes custom intakes for our cars. He said on the dymo it goes up by 5-8 hp. He advised me until someone makes a custom intake that wont suck in hot air or is too long to do any good, to stick with a good drop in filter as K and N. So until the fore-mentioned happens, I shall enjoy the drop in.

Panel filters do not add HP period....a short ram or a cold air intake also offer the added benefit of a re-shaped intake tube as well as a better breathing cone style filter. I was skeptical with RRM's short ram intake because of where it mounts (potential heat sink) but I trust their dyno results as well as the positive feedback from those who have it. I say, go for the RRM short ram.

Are the drop-in filters available for this car the kind that you have to oil? I've been thinking about getting one but would hate to have the messy oily filter on my commuter car. I tried that on a motorcycle and decided it wasn't worth the maintenance hassle. So are the drop-ins dry filters or oiled filters?

They ARE oiled. The K&N uses a cotton or cotton-like cloth with their red/pink oil on it. The Competizione one offered by 500Madness and others is a foam type filter but is also oiled.

when it comes to intakes, air flow management is a tricky thing, leaving lots of conflicting views and opinions on one versus the other.
drop in air filters do more or less for a car depending on the actual design of the oem intake system. Some oem intakes with a drop in run better that any of the available aftermarket open round filter systems. It just depends.
the real key is to design an intake that maintains a good velocity at low speeds, but does not obstruct air ingestion at higher engine speeds. Many aftermarket intakes add hp, but lose tq.
And hp wins dyno pulls, but tq wins races.

if you look at the tortured air path our stock system has you would go with an aftermarket intake. You dont need air flow analisys to see the difference from the aftermarket to our stock one. One is a maze and the other one is a straight tube.

Plenums can help too so what may look like a tortured mess actually may be helpful.
So can cold air, which the stock intake does get it's cold air from in front of the radiator.
I have seen some of the 500 "cold air" intakes with the filter under the hood right behind the motor. Not exactly a good design.
Id take a short ram over a cold air (personally), and the RRM intake isn't really a "Hot" air intake unless you're sitting still, and at that point it doesn't really matter what you have. On the move under hood temps are close enough to ambient temps, to not really justify a "Cold" intake. Also, all I've found is the power curve moves with the different types of the intakes. The RRM at least has 2 sizes of piping, so lower down you get *some* benefit. I just wonder if the step down is smooth(air horn) or not.

That was over 22 years ago, who remembers it. I'll just put a "Powered by Fiat" sticker.
You're going to lose some of the benefit of it being a megaphone if you do that, so get the most "breathable" filter you can find. Don't want to lose the shoutiness.
