Cobb Airbox

[MSMS3]

Here's what happens to underhood temps when the car sits at idle for 5 minutes from a cold start. The temp gauge has two probes. One is sitting under the hood on the rubber mount that formerly held the stock air box, the mount about 3-4 inches away from the MAF sensor. The other sensor is in the gauge and is on the floor next to the left front tire a few inches away from the CAI intake. 32 degree difference in five minutes and climbing. Hopefully the box might slow that down some.

hnda etr, can we get some more data? Please & Thank You

I don't do a lot of stop and go traffic driving, but i'll see what i can do...

I'm just looking for 10 or more minutes of driving, followed by 1-2 minutes of idling. Take outside and intake air temps then please. See my pictures above for a Cobb SRI w/o airbox.

Thank you!

Well, let me see here... I haven't really paid too much attention after installing it, other than my first report...

In the mornings, with AAT's around 76, IAT's are around 4-6 degrees higher.

In the afternoons, with AAT's around 90+, the IAT's are around 7-9 degrees higher. I'm wondering if the heat soak from sitting in the sun all day causes more heat radiation into the CAB.

Sitting Idling - I've seen IAT's 20+ degrees higher than AAT.

Stop and go, city driving, IAT's around 15 degrees higher than AAT.

My conclusion is that the CAB works best at highway speeds and is not as effective at low speed situations because it doesn't offer a complete seal to a cold air source (fenderwell).

Still, it looks cool (wiggle)

So in conclusion, it looks cool but doesn't help really at all. Based on the data I took, we're getting basically the same findings. Thank you for the continued reports!
