Modifying The Stock Intake System on a 3rd Gen

This thread is about modifying your existing stock CAI (Cold Air Intake) Sytem for next to nothing in cost:

When I was replacing the damaged head on my 89, I saw the "Rat Maze" they call the air intake system that Honda engineers put on our cars to make them quieter, or for better emissions, or just to show off, Who Knows?? Lots of off-shoots and stuff... This is what the whole system looks like when out of your car:



The only 3 items missing out of that picture are the filter, the filter housing cover, and the elbow that goes up to the Throttle Plate.

I eventually plan to go with an aftermarket CAI system, once I decide if I want to relocate my battery to the trunk, turbo this baby, or add a hood scoop...

(JUST KIDDING ABOUT THE HOOD SCOOP!) Anyways...

For the time being, I decided to minimize the amount of extra parts involved in delivering air to my engine. I removed everything except the front snorkel coming from behind the passenger headlight, the part that connects that to the air filter housing, the air filter housing itself, the filter, the filter housing cover, and the elbow that goes up to the MAF. Everything else is sitting in my garage. This is what I ended up with:



Now, this left me with 3 holes that needed to be blocked or else I would be sucking in hot air from the engine bay, which isn't good. So, being the innovative and frugal person I am, I came up with a practically "Cost Free" way of blocking those inlets.

Here's what I found:

I recently changed the oil in a couple of my cars and I noticed that the lids on the oil I got was larger than usual. They looked very close to the same size as the holes that I needed to cover. Sure enough, they were. This is what it looks like when they are snapped onto the Snorkel Section:





And this is what the Air Filter Housing looks like:





And this is the Oil that I got the red caps from:





I thought about painting them black to match the rest and "hide" them, but I thought it would be better to be able to see it easily to make sure that it didn't come off, or discolor from the heat. I did the one that is on the snorkel, right by the exhaust manifold over a month ago and it hasn't discolored, melted, or warped so I think it's safe to say that they will be fine, but will still keep an eye on them.

And last, the 3rd port that needed to be blocked. I haven't found anything that is "Plug & Play" yet, but i'm still looking and I have an idea of what to use. If I do, I'll update this thread to show the change. But for now...

I used a hose clamp, some high heat RTV, and one of those cylindrical rubber pads that goes over the radiator hose to make the cover. I pretty much cut the rubber tube down the middle longways, layed it over the hole, folded the edges of the rubber down the sides, and used a box knife to trim it to fit.

There are a couple flanges or "bumps" that the grooves on the old piece popped onto to hold it in place. I trimmed the rubber to fit just above these flanges, as the hose clamp fit perfectly between the flange and the edge. I did the same steps for the back and the front as well, and even though the front is rounded, still cut it right above the flange. Now, it is a little more difficult to fit, but not too much. It's hard to explain but you will pretty much cut the corners at 45 degree angles to make the side folds match up with the front and back folds. Here are several pictures I took at different angles to show how the edges meet and such:









I haven't had any issues with this setup and plan to use it for a bit... At least until I make up my mind about that Hood Scoop!

Re: Modifying The Stock Intake System on a 3rd Gen

I doubt it bit it's worth asking, is there ANY difference in drive feel or would you say this is an engine dress up mod? Cool write up regardless though!

Thanks! I didn't feel much improvement in performance, but you can hear the resonance of the engine a little more. And it only shed "a pound or two" so no real weight reduction.

I mainly did it to get all that crap out of the way so I could see inside the engine bay... So yeah, more of a "dress up Mod".

Re: Modifying The Stock Intake System on a 3rd Gen

Stupid work computer...can't see your pics. But I'll give you props anyway from the description you gave.

I don't have any of my stock intake parts left. I have a short ram intake, which does nothing for performance. But I like the way my intake sounds so it was worth it for me. And the engine bay is a lot cleaner now without all that tubing in the way.

Re: Modifying The Stock Intake System on a 3rd Gen

Yeah, I will be looking for something to replace the stock parts in the near future. I definitely want "cool" air coming in as opposed to "underhood" air... The "outside" air coming in is hot enough as it is!
