I wanted to do the same, but didn't have anything to cut it with and didn't want to. But the next morning, I had an inspiration. So I ran out to my car in my PJ's with a handfull of rubber bands. I took of the lid on the air box and secured the filter with the rubber bands!
Now I can really tell the difference and I hear a great throaty intake sound any time I floor it!
What cheap mod or repair have you done?

well, on my Supra I fixed all sorts of hesitation and and starting problems by JB Welding the cold start sensor plug on there. Turns out the clip had broken and it was gradually getting loose.
I also fixed the heater by unplugging a vacuum line and rerouting another.

I also forgot to mention that the way I mounted the rubber bands was just one at each corner, so four in total. Each was wrapped around the bulges where the nuts were a few times nice and tight.
NOTE: I should remind everyone, check on the rubber bands every now and then! In the first week I had them on, one came off. But since then, I havn't had any trouble with them and they still maintain thier elasticity.
Hope I solved most of your questions

This is total and complete crap, i tried it today because i was bored and it acutally felt slower. the sound was nice coming from the K&N filter but you couldnt hear it over my exhaust anyways, when i do REAL intake, im just going to do a fender well intake with a chunky *** K&N cone filter

ah I got a cheap one! When my battery died and I got a new one yesterday, the mechanic lost a nut from the battery tie down so I turned around and found an old removed battery from a Jeep and it had a (excuse my technical retardation) clamp thingy on one of the little nubs where the two wires on top attatch no idea what to call it) and I took the nut off of the clamp thingy, and it was the right size. Cost, free.

Ok, I did the intake mod that nick mentioned. I gotta say, I did love the sound of it. I did notice a difference using it tonight...a cold night to be exact. The true test is when the summer comes. We'll see how much of a difference this will play.

Lives on the Forum
In the first week I owned the car I took off the stupid ricer pedal covers that came on the car when I bought it. I threw those pieces of crap away. Cost = free. It was a good un-mod.
Best free mod was:
https://www.rx7club.com/2nd-gen-archive-72/how-de-power-your-steering-rack-right-way-440198/
Totally free and totally worth it.
Another good cheap mod:
https://www.rx7club.com/2nd-generation-specific-1986-1992-17/how-build-lower-arm-bar-under-%2415-448638/
Cheap and effective.
I also made a brake master cylinder brace from the scrap metal from the lower arm brace. Very effective, very cheap.

I knew that one guy who said his car felt slower didn't know what he was talking about. There is no way a mod like this which removes part of what restricts your airflow would decrease your performance. Although I would say that the one downside was that I hoped to see better gas mileage from my car but I didn't because I've been flooring it so often now. So I havn't seen a change, but at least I know that my mpg isn't as bad as it would be if I still had the lid and OEM filter installed.

yes there is.... your sucking in hot engine bay air now instead of cold outside air. Slap a cone filter on there with no box or ducts and guess what.. you LOSE power.

free- I just cut the top of the air box out, no need for rubber bands and I dont have to worry about the filter flying off.
When I did my engine swap I didnt research enough and bought an 86 for my 91... Huge headach! In place of many gasgets is that liquid gasget stuff. While changing motors, i cracked the goose neck and just slathered on some instant gasget... it leaks.

or something. But that one takes the cake. It's a Mazda reman and the guy didn't even
know he forgot to plug the AFM back in. He probably doesn't deserve it if he couldn't
even look around the engine bay to see what he did wrong.

I am the stig.
Dead mouse removal mod, removing the AC, free'ing up the aux ports with carb cleaner... all of the usual stuff.
The temperature control actuator for my heater was jammed, so I removed the linkage to the actuator and replaced it with a coat hanger. I'm pleased it.

Yes a cold air box would be better in theory. There is always something better in theory. If I lived in a world where theory overlaped reality, I'd install a mini refigerator on the tip of my AFM. But I wouldn't because of the cost and time. Same goes for the cold air box. Considering the time and money that most would charge, or if you get the useless aluminum sleeve off ebay, it's a pointless mod. My mod takes less than 5 minutes and as long as you have the newspaper delivered to your house, it's free!
Here's something you also didn't consider, and it's actually an experiment you can do: take a normal drive around town today, pop open your hood (after you've come to a stop for god's sake!) and feel your intake manifold. The part that says 13B MAZDA, or even better, further down the manifold. It's hot. Think it through, even with a nifty cold air box your air will always encounter the hot metal manifold that any unmodded 7 will. I dare you to leave your hand on the lower intake manifold for more than 10 seconds. It's very hot and think of your "cold" air passing through there. Air intake does not stop at the filter!
Now, ask yourself- is there really any such thing as a "cold air box?" I'm waiting for someone to invent the cold air manifold!
