SRI to cold for cold weather driving
 
So I installed the Roush SRI last... April. Drove all summer with it installed. Very happy with it. I live in southern Wisconsin and in December-March it gets REALLY cold. I found out that the intake is, well for lack of better terming, too good at its job of getting cold air. Long story short, ended up having to put the stock intake back in for a few months. So it's warmed up a bit and I hated not having noise and some extra ponies to play with. So me and a buddy bought a smaller filter and figured out how to keep as much of the uber cold out.

So we didn't put the snorkel on and plugged the hole and had a brilliant idea to put the HID ballast in the heat shield. And have been running like that for about a week now with no issues and I'll put the snorkel on when we've had a week above 50. I don't know for sure if I'll move the ballast yet. But that's my fun cold weather story for the year.

what symptoms were you having due to the (very) cold air? just curious.

I was driving on the highway and the car lurched and went into limp mode.

When you installed it originaly, did you install the insert that came w/ the steeda sri? w/o it you'll need a reflash. Sounds like you didn't in your post.

It totally shouldn't matter how cold the air is coming into the car.. Afterall if that were the case the stock setup would have issues to as it pulls air from the fender well. If anything the air from an SRI is warmer than the air from the stock setup.. Your issue lies elsewhere.

This. Besides, your a WI/MN guy. If it was too cold just put a piece of cardboard in front of the radiator and let the engine get warm. [hihi]

I have the Roush intake not the Steeda so I don't have an insert to put in.

The duratec pulls air from the crack between the hood and the grill with the stock setup as well as being a big plastic box that does allow for some engine heat to leach in where as the Roush intake is a big powder coated steel heat sink just stays cold because of the air flow in and around it.

I put the HID ballast in the heat shield to warm up the shield and air just enough so that the oil coming in from the breather hose doesn't muck with the throttle body when cruze is disengaged with the clutch. Also since the filter is drawing much more O2 dense air than the stock intake the car runs lean at higher RPMs/Speeds. Next winter I'm going to put an arm band around the smaller filter to lessen the air flow a bit to help with lean issue.

Please don't bash something until you fully understand it.

Thus the removing of the stock snorkel and putting a blocker in that slot of the intake heat shield.

Did you get the codes? What was the outside temp? just curious as said. I am betting (with myself) that your MAF had 'brain freeze'. I.E. The MAF measures quantity of air by temp measurement within a known volume. If you exceed the temp spec, then the MAF know longer knows how much air is entering and goes to safe (limp) mode! Think FORD tests to -40f, but normal MAF 'probably' can go to -50f. things get a bit iffy at the margins.
Hey! it's my theory and I'm stickin to it [wiggle]

I have a steeda SRI,live in Illinois. We have had several sub zero days this winter. My car never had a problem related to the air intake. The battery issue is a different subject though.[rofl]

The car was reading 4 outside temp. Pretty sure it was colder. I agree wholly with freezing the MAF. I dropped the car into neutral and actually turned it off for about 10sec. Probably not my best idea while going 55 but she turned right over and worked so long as I had it engaged in a gear. A bit of trouble at the stop lights but got to work where I tied hand warmers to the outside of the filter and got home without to much greef. I threw the stock intake back on the next morning and had that on for a 2-3 months.
