Steeda intake cover.

my aluminum MAF tube has never been so hot that i cant stand to grab it after i get done with a drive, how ever mine is powdercoated which may have some affect

Thank you for your insight on this matter. I do agree that a closed air box does take more time to shed the trapped heat (heat soak) vs. an open box setup BUT at the same time, closed box takes more time to heat up than an open box.:frusty: Open boxes are more prone to fan wash, especially when both fans are being used (A/C on).

As for open boxes flowing more....I strongly disagree. Numerous reports/posts have been made about the maf lbs per minute of air flow being the same between the open/closed boxes. The TB diameter is the choke point NOT if the air box is opened or closed.

I'm not knocking the product you stand by at all. Steeda has some great products. But I do wonder why you implement an aluminum tube right where the maf sensor resides:shrug: I think you could have better control of IATs by simply using a plastic tube in that area. I bet that you would not want to grab that tube after sitting in traffic vs. a plastic tube design.

If you had a scoop hooked to the factory inlet area and the grille cut out I am willing to bet anything the iats would decrease just as fast if not faster than an open filter and because the initial rise rate is much much slower the net effect is average iats are much lower. The highest I see on the stock airbox is 115* in 95-100* outside temps when the car idles in place for a long time or gets left sitting hot with the hood closed.

Why does PMAS use an aluminum tube just like Steeda? They are engineers and designers just like the Steeda staff. They have tons of data points to support their design and it seems to work really well and why then went to market with what they did.

Like I said above, IATs seem to be beaten to death over the last couple of months, for whatever the reason.

Because it's hot as heck right now here, and Unless you are bringing your own extra oxygen and octane with E-85 hotter IATs do decrease performance measurably, and open filters in the engine bay have hotter average iats even at speed, but mostly I do a lot of stop and go driving and with an open filter my iats get up to 150-160* in a hurry with an open filter (my 2013 had an open Airaid) and take a while to cool off. The ECM pulls quite a bit of timing at 140-150 and car is noticeably slower and even if you tell it not to pull so much the knock sensors will.

True and I am running E85. Hot as heck here in Atlanta, too. 37 days out of the last 45 where it has been 90+. Most of those days are 95+.

I can tell E85 makes a big difference in running in this heat. Glad I can take advantage of it

Totally agree with the beatings:repost: In the end, both types of intakes get hot and get cold.

Data log from my friends 2014 5.0 with a open intake in Texas from a few days ago. First run around 90* iats second run close to 140*. Car is on E-30 blend. 10* of timing difference which is a lot. Car has a FF tune, CJ intake mani with a JLT intake, LTs, axle back, etc.

I hope they put an E-85 pump here soon. I do my own tuning so it's nothing for me I just enable flex fuel logic in my tune and add spark and disable or reduce IAT retard in my tune.

Ugh...this tired old complaint again?

Does it even compute to some of y'all that many of us don't give a crap about trap speeds or thousandths of a second?

WOW...That is a lot of timing being pulled when looking at those 2 pictures.

I would love to be able to tune my own car at somepoint down the road or at least be able to look at the information you have above and be able to decipher all of it and just not 20% of it

I am very lucky where I live in GA. There are literally 10 stations that carry E85 within 15 minutes of my house. The closest being 5 minutes away and that one has been testing out at 82-85% @$1.60/gallon, too

Then why post in the thread? You don't care, so move along. Pretty simple.

I am learning some good info that has been shared thus far and will continue to do so.

And if you look there is zero timing pulled due to the knock sensors it's all due to iats. Knock retard (KR on the scanner) is 0.0 in both cases.

If the throttle body is the choking point, then how does a CAI make MORE power with the same throttle body as the stock air box? :shrug:

The reason we do a billet mass air meter is because a plastic roto-molded one like some other brands, incorporated into the intake tube, will not be nearly as consistent in diameter. If this car was speed density, that’s fine, but it’s controlled by a mass air meter metering the air coming into the motor and with that you want to be as consistent as possible. We did several tests with a plastic mass air before we released these and the temperature was almost identical with both. We stuck with the billet aluminum meter for overall performance and aesthetics happen to be a bonus.

By using a billet mass air meter, we are able to precisely locate the mass air flow sensor - this gives us superior repeatability and makes tuning the intake system that much easier and repeatable. With a roto-molded meter, that is not possible.

With the bellmouth and billet mass air housing, our kit has a more precise MAF signal for better driveability than a roto-molded plastic housing; the plastic MAF housing can have as much as 70/1000ths variance in diameter which is inherant with roto-molding, this can affect drivability.

You missed my point, I'm sick of all the assumptions that IATs should matter to everyone. You certainly have seen the mass of Steeda haters on this board and they all sing the same tune. (pun intended)

My Temps lower just as fast they did without the cover. It's not a perfect seal on the cover plus there's a random hole in the front of the air box. So it does still suck in engine bay air. With the grill being opened up, it helps too. I really haven't seen a down side to what I've done, other than time I've put it. The other issue I see is hoe far back the air box goes, which I would think allows the fresh air from the front pick up, to escape. With the cover, it stays closer to the filter, rather than hitting the back of the box and go upward.

I can do some data logging if needed.
