Cobb SF Intake released

[walti]

If i am guessing this right, and correct me if I'm wrong (sorry for the newb assumption), the sri is getting more power on lower rpms and the cai with higher rpms? And if this is so, how noticeable of a drop in power on lower gears with the cai?

 

[fourthmeal]

With turbo cars, its not an issue of powerband changes. All we need is more flow. CAI's, SRI's...just less restriction, and thats it. CAI's reportedly get cooler (thus denser) air, but SRI's should do this at speed, as well. So, no change despite gears, or speed. You shouldn't lose anything in the bottom end, as the turbo is the ultimate restriction until it spools at about 2500-2700 rpm. Then the turbo is a gain, and the air induction system of your choice will improve the flow into the turbo.

Any of you guys ever pull your air filter out completely from the stock box? Just wondering if the sound difference is somewhat close to an aftermarket cai or sri? Just a thought for us old guys trying to maintain our sleeper status. Was thinking of doing this today and driving around the block to see if it made a difference in sound?

Living in the desert, I couldn't fathom one minute of running without the air filter in place. I can pull a 1/2 pound of sand and dirt out of my engine bay every month. Not worth it, IMO. It only takes one grain of grit slamming into a turbo impeller to cause damage. Fragile things.

420 post, cool.

thanks fourth.. vegas ftw!

we desert rats gotta stick together...

Just installed my COBB last night after work, took me about an hour - the hardest part is just pulling hoses off of stuff (that damned little elbow fitment...) and being careful at the same time. Hit the brakes while negative terminal was undone, to be sure. Hooked her all back up, lemme say, "Wow!" Holy crap the butt dyno makes a big difference, the turbo hisses at you now when you begin sucking in air for a big run, and when you let off the throttle you get a characteristic BPV sound. I can't recommend you get an intake of some kind on your car enough! The car is being held back, like a genius in remedial math. Get yourself an intake, and go COBB or CPE because they've customized an air-flow straightener that will completely eliminate check engine lights and all the issues everyone else is having. No boost spike for me, just LOTS of boost - I killed an Acura TL who was insistent on trying to cut me off this morning. Additionally, my normal acceleration onto the on ramp of the expressway typically nets me around 85mph, today at the same cut off I was going 115. Yippee!

Anybody thinking of/already attaching an Apexi Power Intake to the front of your COBB tubing, and ditching the stock COBB filter? I love it, just wondering about the dual nature of the Apexi...

 

[subparpunk03]

interesting idea. I hear the apexis are dryflow. I had thought about going with an AEM filter.

I will look into it.

Think I'm gonna have to order my Cobb SRI today...

I've been on the phone with Cobb and Apexi for part of the day, getting numbers, looking at possibilities... If anybody out there has an idea, let me know. As it stands, the Cobb intake filter element is 4.5 inches, or 114.3 mm, in diameter. Apexi doesn't make a filter or flange to marry up to such a large opening, the largest they accomodate is about 80mm, with a 160mm filter that goes down to an 85mm opening... If I'd actually ever SEEN an Apexi power filter and not just gotten the press shots on google I may have more ideas... A rigging/tubing of /some/ kind could accomodate the Cobb MAF housing inlet, but would it be worth it, would it still be efficient with more tubing and some random modification to attach it? Hmm.

 

[fourthmeal]

nudge nudge...maybe Apexi will make something for us. Otherwise, I'd like to see their filter as an option with COBB..perhaps a DUAL version for the airflow. Then again, just how big does it need to be?

 

[subparpunk03]

You might want to check out Amsoils filters lineup as well as AEMs. Maybe they have filters that match up.

i just ordered my cobb intake, what benefits are you looking for in changing the filter?

 

[Vindikacione]

Doesn't the stock "coiled" rubber house create turbulance, thus reducing flow?

I would think Mazda uses it for mass production reasons as opposed to performance.

Probably makes only 0.0009% difference on the dyno. Anyone check Cobb versus BEGi Version?

What about rain? Does the Cobb get soaked when it rains?

Does the Apexi filter fit on the HKS or BEGi SRI?

Apexi makes a few diffrent diameter filters the last I knew so one of them should fit. Check out ther website.

I think the Apexi filter is suppose to be very high flow, zero maintenance, and a superior filter ta-boot (meaning it removes more dirt).

I think I'm going to go COBB CRI when/if I ever get an ms3...

To me it looks like the real-world performance difference would be negligible. The up-front cost will be lower. And the install cost is non-existent.

Earlier I was thinking I'd buy a MS CIA from Protege Garage for $310 and have the dealer install it for ~$120 (1.5 hours at $80-per-hour dealer rip-off rate)...

On the other hand; is $255 worth the warranty?

Do y'all think the SRI would be susceptible to hydrolock like the CIAs apparently are?

 

[Falconx84]

they can't void your warranty on an intake unless they can PROVE the intake is what cause the problem

hydrolock is an urban legend..... i have never once seen it happen on the street and only saw one jeep w/ a factory intake suck up some what off-road

most of the time the MAF gets wet - break out the hair dryer or wait for it to dry. The big key is just to not be stupid and drive through a huge puddle accelerating. Get whichever you want, but I'm pro-SRI since it doesn't make a big real-world difference

you wouldn't be saying that if you lived around here, the flash floods from super heavy sudden rains has caused more than enough hydrolocked engines.

It does happen, just maybe not where you live.
