Title: Air Intake
Post by: giant_mtb on August 27, 2006, 10:46:19 PM
So...the stock air intake on my Monte Carlo is extremely restrictive...it's basically a 5 inch long by one inch wide opening into the air box.  I want to get a new intake badly and I've been looking at eBay.  K&N or Fram don't seem to carry complete intakes for my vehicle.  

So I've found these really inexpensive air intakes on eBay...are they worth it?  I mean...they're so inexpensive.  Are they bad?  Anyone?

Here's an example of what I'm talking about... (http://cgi.ebay.com/ebaymotors/95-05-CHEVY-MONTE-CARLO-SS-LS-Z34-V6-AIR-INTAKE-Kit_W0QQitemZ230021447504QQihZ013QQcategoryZ38634QQrdZ1QQcmdZViewItem)

An air filter like that for $6? It's probably a piece of crap that doesn't really filter the air.

I know a guy who used panty-hose as an air filter for years. Perhaps you could try that instead. ;)

Its ricer shiz, no buy no buy. Get a fram boost intake, they are sold wherever they sell frame filters. Or a K&N but they are spendy.

We had a K&N custom made for the 99 E320.

I've looked at both Fram and K&N's websites...they don't have intake systems for my car.

Hmm, then... IDK. Google Monte Carlo air intake.

There's no "system". :P

It's a pipe with a filter on the end! You can get a pipe anywhere and Autozone sells 3" cone air filters for $25.

You know what I mean...where every piece is made and designed by the one company.


Yeah I'm thinkin' of taking the cutsom route.  How I'm going to bend pipe, though, I don't know.

Buy one of those, but ditch the filter it comes with and buy a K&N.

People who spend over $150 on an intake are stupid, it's a tube with a filter on the end.

That's also a good idea and may be the route I might take.  There's a couple on eBay where they bend the pipe and stuff then sell it with a K&N filter...like 40 bucks plus shipping for it all.  Who knows.

Yep, but some people (who aren't so mechanically inclined) like to buy a high-performance "CAI" and install it themselves so that they can feel like they just completed a big project (no offense to you guys that have done that "mod" ;) ).

I may fab one up someday for the Focus because I broke the airbox lid on it, otherwise, I wouldn't even bother.

You can probably buy large diameter piping at homedepot or the like and have it bent for free/cheap. Takes just a second to bend pipe...

So I took my air box out earlier...and I cut off the tiny little plastic hose that goes from the airbox to behind the headlights where it gets its air from.  It's such a small opening.  I measured it...1 inch wide (at its widest) by 4-3/4 inches long.  Talk about restrictive.  So I cut that off and cut a hole in my airbox about 4-5 inches square with my Dremel.  I think it's safe...it's on the correct side of the filter and it's in the same spot as the old hole, just bigger.  

The difference in both performance and sound is literally noticeable.  The sound is so cool!  WHOOOOSH!  It seems to have more oomph under 3K RMPs than before.  I'm not saying it gave me a buncha horsepower, but it's more responsive, sounds better, runs smoother, and it seems to give it some more mid-range punch.

Should I get one of those "high-performance" OE air filters from K&N?  Are they worth it?

They are nice and never need to be replaced. I need to find a snorkel, anyone know a good company too get one from?

I wouldn't, if I could have the stock filter for my car AND an open air intake I would.  But since the sound is too good I'll stick with the aftermarket cone filter.

Here's some pictures I just took of what I did...


Here's the original intake tube...

This is where that tube went from the airbox to behind the headlights...

Hey!  I have a COLD air intake!  The refrigerant resevoir (or something) is right under my airbox!  COOL!  I should use the a/c all the time so that refrigerant's flowing to keep my intake air cool!  OH YEAH!

Actually, by the looks of it that may very well be your A/C system's condenser, which, if working properly, will be hot.

My fam's accord has the most humongous air intake/silencer ever. It weighs 11 pounds, and consists of multiple bending and changing diameter tubes along with a few boxes. Gains are supposed to be pretty good from removing it, but pops wont let me. :P

Chris, where is your creation sucking air from?

Our trucks is a filter sitting on the carb, the jeeps is pretty good, though it has a big hole in the bottem of the air box so it can suck in water.

Basically it's sucking air from behind the radiator and fan...not exactly the coolest place but it's still getting more air...which is what I initially wanted...none of this "cold air intake" crap.

You're right, it does basically nothing at all besides sound loud and increase the Cool Quocient of your car.  The air is about 90 F by the time it gets into the engine at least, and cold air requires your engine to run richer to prevent lean misfire and hence you use more fuel, so it does nothing for efficiency and makes a negligible power gain.  Add a larger throttle body, race cams, and an expertly designed exhaust and then I would think about something like that, but I would rout it into my fender, which is basically where most OEMs get their air from anyway.

But intake temperatures don't really matter on an N/A motor because there's no boost or danger of detonation.
Title: Re: Air Intake
Post by: 93JC on September 08, 2006, 09:37:08 AM
No danger of detonation my eye. Why do you think a lot of new engines recommend 91 (R+M)/2 gasoline?

The effect of cold air induction is proportionally reduced because the intake air in a forced induction engine will heat up substantially over the ambient as it's compressed. Cooling it with an intercooler will markedly improve performance because it's essentially returning the intake air to the temperature it began at (a little bit higher really). The idea of a cold air intake on a naturally aspirated engine is essentially the same thing, but the naturally aspirated engine will not achieve the same increase in power because the air is not as hot to begin with. It will theoretically provide for more power, but the gains in a naturally aspirated engine will be proportionally very small compared to strapping an intercooler into the engine bay of a turbo or supercharged car.

In any case all it really does is allow more fuel to be dumped into the intake charge while maintaining the stoichiometric ratio.

At least your warm-air intake may, increase fuel effeciency and lower emissions.
Warm air is less dense, and while lowering the volumetric effeciency so the engine will use less fuel to attain the proper a/f mixture. In addtion, fuel atomizes better in warmer air, which in turn makes a more complete burn, and thus less unburned fuel escapes through the exhaust.
You could also take the intake temp sensor probe and stick it between some radiator fins, then it will really lean out your mixture.
Maybe open up your spark plug gaps a bit.
Get some tall, skinny tires and run them a high pressure.
Tape off all the seams in the body.
Consider a water injection system. This will help counter the lean mixture as well.
Oh, I may have gotten a bit off topic...

That is a really silly idea.  Want to wipe out your catalytic converters or burn your exhaust valves then go ahead, but otherwise I don't think that is a reasonable plan.

There are at least a dozen other ways to adjust AFRs without doing something so drastic.
