Default Advice on a CAI

I was looking around (here) and elsewhere trying to decide on a Cold Air Intake. I know that everyone says COBB is the best but theres just no way for me to afford that one right now. I've found that the pricing for the PDM intake is really low ($50) and is the same principle as the Ganzflow intake which ive seen that many people also like, but half the price.

Whats the opinion of the PDM? How much does it help, whats the sound difference, etc.?

Id appreciate any info you guys could give.

duuude, like they said... cobb is great i got the intake on my 02 rs.. great sound... noticable gains... cant say anthing about any other product, but i will definately say cobb is definately worth the money, just give it another two weeks until you get your next check and get the cobb.. thats my opinion, take it for what its worth.


edit:
unless you dont work, just save up anyway! this is your ride!!! definately do it right and get a quality product... im sure that there are other quality ones out there... but from personal experience i would definately recommend the cobb intake.

Thumbs up

I was in the gung-ho Cobb camp until I got my [used] GanzFlow. I still say that Cobb is the best for power gains, but since I got my Ganz for 1/5 the price of a new Cobb, I don't think it was as good as far as bang-for-the-buck. I'll probably upgrade it later when I get really serious about maxing out horsepower. Right now, I like the sound more than he 3 extra horses.

Performance-wise, yes the Cobb unit seems to create the biggest round of applause.

However.... Units like the PDM and Ganz have their advantages, too. Primarily, for those interested (like myself), they retain the OEM airbox. Which is good in that it has drain holes built in, good if you ever should ingest water into your intake. It at least has a chance of escaping before being sucked into your engine.

I think the Cobb has some sort of filter setup in it, and no there aren't a lot of documented cases of water suck with Scoobies, but there was one about a month ago. Somebody got their Cobb clogged with snow/slush, which around here in NH could happen damned near every day from November through April (considering we just got six inches of snow last night, too...)

To me, the added protection is worth a little loss in performance.
But to those using their cars in inherently less climate-imposing areas, or who will race a lot or simply don't worry about this, then a Cobb will be worth saving up for.

Which one of these setups has a filter that you can get to easily? I don't care for the filter-in-the-fender approach myself. It's probably great for CAI, but I'm sure it sucks for maintenance.

maintenance wise the cobb is not a problem. The filter does not actually sit in the fender well. its just before it, with about 8 inches of piping going into the fender well. it is easy to unbolt.

Default drain holes in OEM airbox??

Siper2: is it really true that there are drain holes in the OEM airbox? I'm curious as to where they are and how they would work. I was thinking of retrofiting this onto my ganzflow:

First off, of course you never really can be too careful, and adding the bypass valve won't hurt anything. But, it's unlikely you'll ever have your passenger side fender in 2.5'+ of water. AEM designed that valve b/c their M.O. is to place the filter as close to the ground as possible with their kits. Since the outermost intake point of the Ganz is barely inside the fender well, you don't really need it.

Yes, SAVE UP. Scour the Private FS. You will find a deal. This way you'll have no regrets and won't be thinking "I wonder if I had a cobb".

Default low end

i read that keeping the stock box, ala ganz and pdm, maintains your low end torque, where I heard that ones that dont, actually sacrifice low end torque.

As for me, i am thinking of getting an intake that keeps the stock airbox.

I had a ganzflo a year ago, and sold it because it rattled.
I just went to imprezars.com and found out they had made adjustments to the design so that it fits more stably, and therefore doesnt rattle.

I've had both Ganz and Cobb. I got Ganz first and went to the Cobb. I have a few thoughts..

Cobb vs. Ganz w/K&N panel filter
Cost: Ganz (but it doesn't come with filter)
Throttle Response: Cobb
Power: Cobb
Sound: Ganz (not much louder than stock which I like)
Fit: Cobb
Looks: Cobb

Honestly I think they are both good. Cobb is just better, but I hate the sound at WOT. That's just my opinion though.

Default sound at wot

can you describe a little more the sound of the cobb at WOT, and why you dont like it? I assume you mean its too loud?

When you say power gains go to the cobb, you mean high end, i guess? What exactly do you mean by throttle response going to teh cobb, as well? I have never had the cobb, but am curious.

I know the ganz with k&n cost around 140, but the pdm intake i tihnk is identical to the ganz (piping size and shape), and wiht a k&n, would cost under 100 i think....

so lets assume the cobb is 200, adn the pdm with k&n is 100.

is the cobb worth the extra 100 bucks, especially since you have had both?


thanks

Dan

Yeah, I figured I had a newer one (got it used, so I didn't really know). How far down does yours go?

I think the Cobb is just to loud. It's not my taste. I think you can hear it in the link I posted.
When I say power I do mean high end power. That is what an intake is for. You will not get gains from any intake at lower rpm's. Just not going to happen. You lose very little with both the Cobb and the Ganz, but 4-5k the cobb gives you more power for sure. By throttle response, I mean when you hit the throttle the car reacts faster with the cobb.
I do think I would buy the PDM before I bought the Ganz, but....

Okay I think the Cobb is worth the extra money. It does what a CAI is supposed to do. Gives you more power where the engine needs more power.

Default Ahhh

Ahh, how quickly do some of us forget. Remember there was a test between stock, Cobb and throttle body mounted air filter in this forum?

It wasn't a horsepower test but more like temperature, velocity, and a couple other factors. The throttle body mounted air filter (with the hood scoop removed) performed better than the Cobb intake. I'm searching for the post now but I'll post it up. I saved it on my computer at home but I'm at work.

Edit:

Ah, here it is.

Test #2

Test #1

Man, I love that Test #2 (Thanks again DCrawford). Gather what you may from the test(s). I'm just providing info.

yes those were interesting tests, and I remember them. However I have an 02. No hood scoop. 2nd if you are worried about water with a cobb then the throttle body intake should sure as hell scare a person. It would be cool to see some dyno testing done.

BAN SUVS: my ganzflow is in the fender pretty deep.. I did a measurement, and it's about an inch or two away from hitting the fender. I was thinking of sawing it down a bit with a hacksaw so that it doesn't go as deep.

I have a filter mounted on my TB. It sucks, I don't know why anyone would do this. It sounds like ass and the car is very sluggish. I had a Rallispec tube on their before and it was much better. I should be getting a Cobb next weekend, it's quieter than the Rallispec and better throttle response than the TB (I hope).

Get headers... they make sure you don't hear the intake...

The Cobb Intake was always the loudest thing on the car until the MRT headers went on...

Default Thanks for the advice

Looks like ive touched on a heated debate...

I appreciate on the advice and it looks like i'll be holding off for the cobb which will be more of a wait (moreso according to 2.5rsmatt). It looks like those that didnt have it wish they would've and those that do really dig it. I did listen to the intake in the movie posted and like the tone given off so the sound wont be an issue for me.

Thanks for all the posts..
