I'm not sure a CAI would even be that much better than an SRI on our cars...

[spotch]

I've been doing some thinking about getting an SRI for my 2010 2.0 5speed (specifically the corksport one) and part of me is worried about the fact that the filter on any SRI is going to be situated so close to the radiator fan that it's basically going to be sucking in a lot of warm air. Then again, when I take a closer look at where a CAI would likely place the filter, (probably about 3-4 inches further from the engine and 6-8~ inches down) it seems like it's still not going to be all that far from the radiator fan exhaust and because of all the splash shields lining the bottom of the engine bay, would end up sucking up most of the same air (maybe a little cooler), just with a further path to bring it back to the engine.

Thoughts?

What? I'm just saying I think it's harder to make a case for a CAI on a 2010+ 3 than it is on other cars where the engine bays aren't as sealed off.

search button is your friend. use it.

i have had both the CAI and SRI on my car. diff in temp between the two was 2-5 degrees, and that temp was 5-10 above ambient

I did search the 2010 forum (since the OEM intake piping is different). Thanks for the info though, I'll look for your post.

so the piping is different, laws of physics are the same.....how different can it be since the 2.5 is essentially a .020 overbore of the 2.3......

I'm not talking about the 2.5, I was posting about the 2.0. I know the engine is largely unchanged, the underbody trays are different as is the oem intake piping. Seems like there's basically nowhere to get 'cold air' to the engine on the 2010+ ones, which is different from any other car I've seen (which had less-sealed-off engine bays/gaps for the CAI filter to get fresh air) and apparently different from the pre-2010 ones, on which the stock airbox drew it's 'fresh' air from BELOW the airbox (implying that there was somewhere for a CAI on the older 3's to get cold air below the airbox) vs in front of the radiator (like on the 2010 ones, because the area under the airbox on the 2010 seems sealed off).

That, and I didn't think the results on a turbo 2.3 would be the same as on an NA 2.0, since the air temps at the TB on a turbo car will be affected by the type of intake you have, but the effect will be muted because the air will have already been compressed, sent through a bunch of piping, then cooled again, before it even got to the tb, vs just being moved sucked through a filter and moved 6" before being sucked into the engine.

all cars have an IAT. I can see the temps at the maf right after the filter (IAT), and in the manifold (BAT). the 2.0 is the same block, just not stroked.

Ahhhh, ok good. I knew about the block being the same, didn't know you could get temps at the MAF (this is my first MAF car lol). Well that's helpful then. Thanks

For your info, a 1st gen CAI or SRI will fit on the 2nd Gen. The filter will sit behind the driverside headlight about 6" down from it. The air is definatly cooler over there vs a short ram. not that you would actually "feel" the difference

A few intakes for the previous gen have been causing CELs. I test fitted the Simota from the Mazda 6 2.5, and it works great, 2.0L version available. It doesn't have an open filter like the CorkSport. Here is my review on it.

[Sean2010]

Yea, I have the Injen CAI and it works great too. No CEL and fits like a glove

 

[nondual]

Remind me what an SRI is?

 

[wingzero_]

short ram intake

 

[JS + MS3]

the temperture difference between SRI and CAI is pretty much negligible while the car is in motion. so, my honest opinion is to go with SRI as it is easy to install, clean, and blah blah. it's been discussed to death in Gen1 MS3 section. :shrug:
