Hey guys, im not really looking for an intake, but i was throwing around the idea for one. i would like some sound, but not risk losing any power. I have read about the Cosmo CAI, and i dont wanna spend that because im gonna eventually putting a S52 in. I found this intake on ebay and it looks like it properly positioned to not suck in hot air. I was also thinking i could put some heat wrap on it to keep the heat off the metal tube. What are your thoughts? Just keep the stock system? thanks guys! http://cgi.ebay.com/ebaymotors/BMW-Z...ht_3644wt_1167 Alec |  |  | | 03-06-2011, 09:36 PM | #2 | | Senior Member Join Date: Mar 2005 Location: Portland Or Posts: 2,666 |
Fogg the air box...  I believe its been the hands down performance winner, unless you have a 95 which already has a CAI.... Stock... Dave __________________

I have a 95 I'm from the uk so not sure what you mean by fog the air box and CAI. Could you explain a bit more please.
Cheers

CAI= COLD AIR INTAKE.. a Fogged air box is just running a 3-4" inch diameter tube from behind the fog light into your stock air filter box..need to cut a hole the size of the tube you use and covering the already existing one.. i did this to my air box and well felt slight improvemt took me around 15-25mins to make and install and around 25-30$ worth of materials | | | | | 03-08-2011, 09:33 PM | #5 | | Junior Member Join Date: Feb 2011 Location: lancashire Posts: 22 |
Ahh right so as mines a 95 no gains to be made? Looking at the air box mine looks very restrictive. I might knock up a remote cone filter lower down and more forward. Mine has no fog lights so the blanking plate could be removed to make a good front mounted air duct. | | | | | 03-09-2011, 01:10 AM | #6 | | Senior Member Join Date: May 2009 Location: Orange County, CA Posts: 2,019 |
I am about ready to install this bad boI  | | | | | 03-09-2011, 01:49 AM | #7 | | Senior Member Join Date: Jun 2009 Location: Miami, FL Posts: 874 |
my car has no fogs either so i took the fog cover off.. ran the air duct from there to the front of the air box... inside the engine bay it looks pretty clean.. it just looks kinda sloppy at the fog light... i need to do something about that.. but besides that well is pretty much the same thing as a CAI and well is like 80 bucks cheaper than the cosmo racing one | | | | | 03-09-2011, 06:19 AM | #8 | | Senior Member Join Date: Mar 2005 Location: Portland Or Posts: 2,666 |
The 95 already gets its air off the grill, ahead of the radiator. The opening is plenty large and the 95 does not have the foam in the air box or the long intake like the M44. I have a hard time believing any CAI without a AFM replacement is going to do anything. I worked on a project one time where we used a flow bench to test the door style AFM units. The Bosch ones like the BMW were almost invisible from a restriction point of view until you got to some ridiculous flow rates. Way more than the M42 would get to without hitting about 8000 rpm. Basically it provides noise... Dave __________________

Cheers Dave for clearing that up for me .. so a new air filter panel is all I need. I'm not into noise I'm 43 Ffs :0)
I'll probably get one of those midnight racing chips (110 quid delivered) and call that a do for engine mods..
Thanks again.

Yea, the restriction points are fairly obvious as you look at each part of the system. I have thought for quite a while that the boot from the air flow meter to the throttle body looked like the best potential improvement but have not found a replacement that I like. The stock rubber one has the accordion looking bellows in it and that's gotta be causing some weird turbulence....

bavauto has a silicone replacement for that boot, I almost got one until I saw the price  | | | | | 03-10-2011, 07:04 AM | #12 | | Senior Member Join Date: Mar 2005 Location: Portland Or Posts: 2,666 |
Yea,,, I can't convince myself to spend the $$ yet, bit when you really look at the whole intake path that bellows is definitely suspect...

If it has started crumbling, go ahead and dump it all out, you're just sucking pieces of it into your engine (from the lid) and making your filter dirty with the stuff in the lower part of the box. | | | | | 03-16-2011, 05:50 PM | #14 | | Senior Member Join Date: Mar 2005 Location: Portland Or Posts: 2,666 |
This guy posts on M42club.com http://cgi.ebay.com/ebaymotors/BMW-E...item1c19f03091 I could see it working pretty slick in my 95, if I needed space like for a DASC... Dave __________________
