Beginner Intake Trick

[92DX]

Ok, this what I believe every beginner CB7 tuners should do. You dont really need to buy expensive air intake kits. What should do instead is this:
- Your air box have two extensions. Remove both intake extensions. This way more air is getting in more freely.
- To take it even further, put in a K&N High Flow Air Filter
- To take it even more further, cut out holes in the air box. Make sure you dont cut the parts that are passed the air filter, you don't want unfiltered air.

wouldn't you want to filter the normal air intake also tho

both the normal and cold air extensions attach "pre" filter. so even if you take out both, the air still is being filtered.

Both intake tubes feed from inside the engine bay, so there is no cold air. They both draw air from just behind the headlight. They both connect to a resonator that sits down in the fender, but is completely closed off.

Even if you remove the tubes, the inlets into the airbox are still restrictive, so the best thing to do is to remove the upper tube, and use a hole saw to enlarge the hole to accomodate tubing with a 2" INNER diameter. Then get a plastic tube, aluminum tube, piping, or something of that sort and put them in the larger hole in place of the stock tube.

A 2" Inner Diameter tube, plus the stock lower tube will give you a flow area just slightly larger than the flow area of the Throttle body.

The K+N is also a good idea.

The reason for putting the tube back into the airbox, is to keep it quiet. It won't be much louder than stock.

From my experience, both tubes draw air from outside the engine bay location, the whole idea is to get colder air, and this is what the system does. the first is from the fender wall, and the second is from a hole near the headlight, however this may vary on certain models. Right now I have both mine disconnected, works for me.

Actually the extension tube for the normal air intake is the one that gets air from the sidewall and behind the headlight (very restrictive). There are two extension tubes from the air box. The cold air intake (the lower extension tube) goes down through a hole in the fender. This one is the one you wanna keep on.

[owequitit]

The bottom tube does not go staight down into the fender. It pulls air from right behind the headlight. It just runs below the upper tube. The part where you see it "going into the fender" is actually the tube hooking up to the resonator, (a big square box behind the bumper) that DOES NOT receive cold air, or air from outside the engine bay for that matter, in any way shape or form.

Every stock 90-93 intake system is identical.

You aren't going to make me get the camera out are you?

I just did away with the whole thing and the snorkel that was near the fender, and I get better flow.

where do you cut the hole in the intake box..how big should i cut it??

You can pretty much cut out holes any where in the air box, as long as it is still below the filter. I cutted out 2.5"-diameter holes on the side and the bottom. My intake got louder a little, but throttle response is hella good.

hows about you just drill holes in the retard box in the fender remove and seal the normal air tube and seal the inlet on the other tube aswell look cheapo cold air intake im a genius that cantspell

[Aaron]

man drilling holes? sounds like more of a pain in the ass than installing a cai...just buy it off ebay and get a good filter

[HF22T]

fuck i bought an intake from a 90 civic hatch and it fits fine

The whole idea is making the most of what you got. Drilling holes isn't really that hard. Plus this way there is none of that annoying whistle that you get from cheap intakes.
