Another Cold Air Intake thread

Well I'm Pretty sure im gonna get the AEM instead of the K&N But i dont know anything about the MAC filters so does anyone here have one?

also Mod bargins is selling the AEM for 250 ish and Junes modified is selling it for 229, all though im hesitant to buy from junes as i've heard it takes for ever to get your product so i dont know what to do...

Save your money! Do you realize your OEM intake is a CAI?

The air filter is enclosed. The air actually enters the air box from behind the headlight I think?? The factory system is actually better in my opinion anyway, because if you get into water or something like that off road, it won't get into your air filter when it splashes up into the engine compartment. Just my .02 Also with the factory air intake there is no chance of sucking in hot air from the engine. 10-15 horse at the wheels is at like 5500RPM. The only thing a CAI does is make extra noise. What I'm trying to say is a CAI is ok for your street rod, but not your 4X4...

Exactly! The OEM intake pulls cool air in through a snorkel on the passenger's side of the radiator.

Changing to a different cai isn't going to make your truck go faster... well not quite true, your wallet will be lighter.

The K&N kit only adds 7.xx hp to the wheels. I wouldn't call any of these aftermarket intakes "Cold Air". The darn "heat shields" don't work too well......i think the filter on these aftermarket ones get hotter than the stock one, thus losing any gains you may have gotten.

The stock intake is restrictive because of the silencer. Remove that and it's not as bad.

Second, the stock intake is subject in deep water or faster runs to ingesting enough water to cause hydrolocking.

Some people build a cold air box around their cone filter intake, or even build and enclosure out of the remains of their stock air box. If you offroad in deep water, bad idea.

The reason the other intakes can increase HP SOME (and 10 to 15 is extreme and more likely with much bigger engines) is it removes that intake restriction in the stock silencer that goes behind the headlight and the straight path reduces resistance and turbulence loss.

If you are an offroader, you should be very careful. I personally know 3 people who experienced engine damage from hydrolocking -- in some cases totaling the engine.

I took my air box, removed the silencer, and swiss cheesed it all around. I don't get "cold air" -- but I do have to have the water rise all the way to the filter element before I suck in much water.

Don't believe it works? Watch this movie of my truck:

Here's a very brief video of Travis hydrolocking in the same spot WHEN IT WAS SHALLOW! He had a boxed cone filter:

http://video.cardomain.com/Clip.aspx...9B78D9804288EA

He barely made it home, and the engine was toast.

Here I am, same trip, just before him making the same crossing at the same depth:

The stock intake IS NOT restrictive! Just try and measure a vacuum in the intake tube between the throttle body, and air box at WOT, and high RPM!
Matter of fact, block of half the OEM paper air filter, and repeat the test!

WRONG! Measure the drop between ambient and the air box at WOT. You're measuring in both places AFTER the restriction I cited. If you're going to be insistent, at least be accurate and try to respond to what I said. The stock box intake nozzle is quite restrictive and if you say not then you're just trying to be right without knowing what you're talking about.

Don't want to spend money for an intake or intake mods? Fine, then don't. Don't try to justify it though by citing things that have nothing to do with the argument.

Swiss cheesing is drilling holes on all 4 sides from just below the filter to the bottom of the box to keep an air path to the filter during high water, and to allow quick draining of water that does enter.

That simple mod, in and of itself, gets rid of that tiny tube, lol. Wait till you see how small the bore is in that silencer.

It sounds nicer too if that matters to you.

It's nice because you can try it out and it's reversible.

Did that mod on my 2000 2.5L... Made a huge difference... Sound wise and I could feel a little more power under my foot even with the 2.5L... It's definitely worth it man!

IMO the MAC intake is worth having, the others are too pricey.

the MAC filter is the same as the k&n filter.

also i like running an open style oil type filter. it does not allow the water to destroy the filter and let it pass through. i have a cover made by K&n you can run a hose on the filter and it will not let water in.

I have one too and I'm happy with it. I don't go through big puddles like I used to, but that's ok. One of these days I am going to cut up the stock box a little, swiss cheese it and put it around my cone filter to act as somewhat of a heat shield and maybe keep some water out when I still end up going through water.
