I picked up a ISO USB Scan tool from ScanTool.net and decided to play with it. So I hopped in my car with my laptop, hooked it up to my OBD and did two test runs. Also I could probably install the Cosmo Short Ram Intake blind folded now. Just a note, I should have done this before rush hour traffic started to pile onto the parkway. The setup: Stock - 100% Stock, no fogging, typical M44 airbox with insulated air feed running over radiator, foam removed from inside the airbox on both clean and dirty sides and resonator is still attached. OEM BMW Paper Air Filter. Short Ram - Comso (not Cosmos) Short Ram Intake with their air filter (also oiled), no Heatshield, insulated air feed running over radiator left in place (don't know if this helps or hurts.) My findings, Stock air box keeps the air temperature consistent regardless of speed. Meaning it's more insulated than the Short Ram Intake (SRI). SRI absorbs the engine heat at low speeds, but once you've reached a higher speed, air temperature is about the same. Maybe a few degrees difference. I'm no scientist or engineer so don't quote me on my hypothesis So make your own conclusions. __________________ BMWCCA #403399 2012 Mini Cooper S Clubman, 6-Speed Loaded 2001 325xi, Winter Package, 5-Speed Traded 1998 318ti, Active, Automatic, TOTAL LOSS R.I.P. 10/20/08 Bilstein Sport Shocks/Struts .

I could have paid more $ for the CAI ($ I don't have), I could have done the modified Cosmo CAI too. I didn't want to cut my brake duct and relocate my horn. With the performance differences between the CAI and SRI being minimal and I was doing it mainly for looks and sound, I ended up going with the cheaper of the two. Also with the CAI you run the risk of hydro-locking the engine, and well I just don't have deep enough pockets to run that risk. I live in an area where flash flooding is like the haze in downtown LA. __________________ BMWCCA #403399 2012 Mini Cooper S Clubman, 6-Speed Loaded 2001 325xi, Winter Package, 5-Speed Traded 1998 318ti, Active, Automatic, TOTAL LOSS R.I.P. 10/20/08 Bilstein Sport Shocks/Struts .

Well at the time i didnt know about that stuff, plus i didnt have the shield that goes right in the corners right underneath the brake ducts to atleast splash the water down. Im considering running the pipe to the ground again. I guess i dont learn. But i bought that plastic piece now, and now i know to be careful through puddles. | | | 07-26-2007, 03:38 AM | #8 | Senior Member Join Date: Nov 2006 Location: Stamford, CT <-> Boston, MA Posts: 1,393 | It's been a while since I made any progress. Earlier today I picked up some aluminum sheet metal and started fabricating. Of course I chose to do this at night so there wasn't much light. I snapped two pics quickly on my awesome camera phone, one of the images decided to corrupt so I've only got one angle Anyways. I plan on putting a bottom to the heatshield, and possibly even a top. Maybe even a cold air feed. edit: I just noticed how poor the picture came out. To narrate you through, the obvious piece of the heatshield is between the air intake and the belts area, this extends to the radiator reservoir. Directly below the MAF is the continuation of the heatshield (still all one piece) that extends to the wheel well. __________________ BMWCCA #403399 2012 Mini Cooper S Clubman, 6-Speed Loaded 2001 325xi, Winter Package, 5-Speed Traded 1998 318ti, Active, Automatic, TOTAL LOSS R.I.P. 10/20/08 Bilstein Sport Shocks/Struts .

Something like dynmat thermal wrap. You should be able to get a small square of it at any good car stereo shop. That will completely insulate it. | | | 07-27-2007, 12:59 AM | #12 | Senior Member Join Date: Nov 2006 Location: Stamford, CT <-> Boston, MA Posts: 1,393 | Quote: Originally Posted by mohaughn If you want to make it even better cover that sheet metal with some thermal insulation.

There aren't any (to my knowledge) car stereo/alarm places around here to check out __________________ BMWCCA #403399 2012 Mini Cooper S Clubman, 6-Speed Loaded 2001 325xi, Winter Package, 5-Speed Traded 1998 318ti, Active, Automatic, TOTAL LOSS R.I.P. 10/20/08 Bilstein Sport Shocks/Struts .

My only screw up was not making my own CAI. I want to make something like the Cosmos intake, where it dips to where the horn is. Just like the modified Cosmo intake. That would solve the problem of the cold air feed and most likely wouldn't need heat insulation on the heat shield. __________________ BMWCCA #403399 2012 Mini Cooper S Clubman, 6-Speed Loaded 2001 325xi, Winter Package, 5-Speed Traded 1998 318ti, Active, Automatic, TOTAL LOSS R.I.P. 10/20/08 Bilstein Sport Shocks/Struts .

I opted for posterboard to make a template. Duct tape to hold the template together. Scissors.. Tin snips to cut the sheet metal. A workbench helps out too.
