With Chris142's rant on cars he hates, thought I would bring up a huge pet-peeve of mine: modern 'airboxes' and the filters used in them.

I had a 1985 Buick Skyhawk (TBI), and a 1986 Honda Civic (carb) that had nice, round 'pieplate' air cleaners on top of the engines. Just unscrew the centre tab, remove a couple of clips, lift the lid off, and then easily pop the air filter out. The round air filter itself had a nice solid frame around it, and could be held up and inspected with ease.

On most modern cars, you have an 'airbox' that the air filter is in, and you usually have to undo some weird clip, and the 'separate' the two halves of the box to get at the air filter. The halves usually do NOT come apart easily, so you have to wrestle furiously with it, and try to get the air filter out w/o ripping or crushing it. When you DO get the air filter out, it is sometimes a very flimsy thing, with open pleats that flap about.

Then, after you put an air filter back into the airbox, you have to get the two halves of the airbox back together, which again is a wrestling match, and you never really know if they are together properly, b/c the airbox is often sideways, or tucked down low...

Finally, the price! AF's on the two cars I mentioned were about $3-4 a peice. I replaced the one on the Skyhak every oil change, it was no big expense. But, as many know, modern panel air filters can be $30-$60 easily for some. I fell 'lucky' that the one for my Tribute is only $12...but stil, getting to it is a hassle.

Why can they not make small, round pie-plate air filters again that go on top of the engine, and get ducted to the TB, like modern 'air boxes'? Those round air claners can be made to seal just fine, I never had dirt problems with the two cars mentioned above...is anyone out there with me????
 
Pressurized boxes offer several advantages, notably that you havea pressure effect. It also allows for Helmholtz resonators to tune the intake sound and quiet things down as needed.

I agree that it's a PITA to change them sometimes.
 
On my Cherokee and Ranger the factory boxes also offer good protection against water.

And on the Ranger it actually works as a CAI.

You can do all that with a pie-plate housing too. The filter element would just be downstream of the sound-damping resonators instead of upstream. And the whole thing can still be pressurized by ram aid (google "Mopar Air Grabber," "Chevrolet Cowl Induction," or look at a Buick GSX intake system for example.) There's not ANYTHING fundamentally different about the modern way- its just packaging and getting the filter off to the side so the hood line can be lowered down right on top of the engine.
 
I agree the modern boxes create are a horrible mess for DIY air filter changes. A friend of mine did $100+ of damage on his wife's Chrysler Pacifica trying to do it himself.

When I took my 3.5L V6 Camry (with one of those horrible super tight engine compartments) in for rountine maintenace, Bob Tyler Toyota (Pensacola FL) changed my air filter for $19.95 .... with no charge for labor.

Then there is my rant ..... those eco friendly cartridge oil filters that replaced the good old spin on kind .... basically forcing you to go to the dealer for an oil change.
 
my only rant about air filter is on my car. You need a torx socket to get the filter housing apart. Now i have plenty of torx sockets and bits so that's not the issue. I just think its a bad place for torx.

Nothing hard about changing a cartridge oil filter. Undo the filter canister's top, yank out the old cartridge, put the new one in and seat it. The cartridge on my Cruze is right on top, with lots of room to access it. The only hard part is rummaging through my tool box for my 24mm socket, an extension, and a ratchet to take it off.

The air filter housing on the Honda is 4 clips and it's off. The Cruze has a zillion #1 Philips screws to remove. Those will be sure to rust/cam out by the time filter replacement is due. They might be replaced by proper bolts or Allen-head/Torx screws that are much less affected by rust/camming out.

The G37 coupe's two filters are dead easy. If you want a nightmare, try it on my 1991 Audi 200 Turbo. A bunch of the turbo plumbing has to be removed, along with the airhorn and the headlight, and some miscellaneous fuel line brackets. Then you can open the clips, and reach in through the headlight slot and wrench the old filter out, tearing it. The new one slides in not too bad. Then you put everything back together. To actually properly open the air filter box all the way, you would have to undo the motor mounts on the passenger side and take off fuel lines. It's a good one hour job the "shortcut" way that I described. That includes me dropping a screw into my turbo and fishing it out with a magnet.
 
This is another reason why I like to install K&N intakes on all my vehicles. Checking the air filter, if needed, is as simple as popping the hood and looking down.

Cartridge oil filters have been around since before the 1960s. It didn't prevent anyone from changing their own oil back then. And the modern cartidge filters are 100x easier to change than those. They're even easier to change than spin-on filters. I WISH my cars had cartridge filters.

Exactly. Our old Y-block had a cartridge, and it was super-simple to change. My S62 has one.... Same observation.
 
Air filter boxes of E430 and S2000 are very easy to remove to change the filter, both cars have 6 clips to tied the cover to the air box.

LS400 air filter box needs a screw driver to remove, but not to bad.

Cartridge oil filter of Mercedes W210 is so easy to change, even my wife can do it without spilling a drop of oil on garage floor (after I showed her how).

Cartridge oil filter holder is in center of the picture.

The one in my Mitsubishi is not too complex. By moving the intake duct out of the way, I can see the air filter and then decide when it is time to change it.
 
I'm going to agree with the OP on this one. I fought a 99 Dodge truck air filter for 2 hrs on Monday. Finally the owner decided to help and broke the ears off so now it's not filtering anything.

This setup uses a big hose clamp to clamp the upper part of the air filter to the throttle body. A stud and wing nut would have been fine and easier to work with.

Some FWD GM's are a real pain. I forgot which models but I hate them.

The one on my Jeep isn't too bad once you remove the grill support rod. Cant do it w/o removing that.
 
Oh yeah, those 90s Dodge pickup boxes are stupid. Another one I hate are the 90s Caravans - the ones that are in front of the transmission and you have to unbolt the silencer/intake tube from the radiator support to get to it.
 
The easiest I have ever come across is on Nissan Maxima 3.0 engine; 10 second to take it out and 10 second to put a new one.
