hi all, i have the K&N 57i air intake and since joining this forum i have seen that many of you have the cosmo set up. i like the long arm induction kit by cosmo. i would like to know is it better then the K&N setup that i currently have?  thanks |  |  | | 05-05-2007, 07:04 PM | #2 | | Senior Member Join Date: Jul 2004 Location: Florida Posts: 1,595 |
Probably. Is the K&N just a filter? Any piping? Pic? | | | | | 05-05-2007, 09:15 PM | #3 | | Member Join Date: Feb 2007 Location: London UK Posts: 45 |
urm i havent got a photo but the filter is directly connected to the intake sensor lump and i have run a hose from where the fog light is all the way up | | | | | 05-06-2007, 09:26 PM | #4 | | Senior Member Join Date: Jan 2006 Location: lancashire, england Posts: 300 |
the cosmo intake is better than a k&n 57i cos' the filter is further towards the front of the car. you can do this yourself though with a 76mm 45 degree alloy tube, raid hp sell them. you will need to relocate the alarm and horn though. still, a cosmo intake isnt' as good as a fogged stock airbox or an enclosed induction kit. __________________

Yeah, the k&n is robbing hp from you. It is sucking in heat like crazy. The cosmo intake is a good option or like CosmoSchwarz said, the fogged air box is a great cheap mod. Do a search and you will find the thread about it. If you need an air box I am selling mine with a K&n flat panel filter for $55 shipped. http://www.318ti.org/forum/showthread.php?t=15599 Pics are on the bottom of the thread. | | | | | 05-07-2007, 04:29 AM | #6 | | Junior Member Join Date: Jul 2005 Location: Ohio Posts: 4 |
I have the Dinan Cold Air Intake setup and am really happy with it. It has a tube, heat shield and filter that is located in the front fender under the front head lights...the front air intake duct in the front lower bumper has a flap that works to also help to get air to the filter element. I have a '99 ti sport with the M3 front so it has the 2 intake ducts for the front wheels/brakes. The Dinan setup keeps the hot air from the engine compartment from being sucked into the intake via a heat shield. The car definitely performs better and sounds better besides. | | | | | 05-07-2007, 06:28 AM | #7 | | Senior Member Join Date: Jan 2007 Location: Los Alamos, NM Posts: 344 |

http://318ti.org/forum/showthread.php?t=14920 that is my current set up....modified cosmo intake... i have had the debaffled airbox with paper filter, the fogged airbox with paper filter, fogged airbox with kn filter, cosmo stock intake, modified cosmo short ram with a paper cone filter, and my modified cosmo cold air intake with the cosmo filter. i like the modified cosmo the best out of all of those...the cosmo set up itself has a few design flaws in my opinion, but it gives you the materials to make some options yourself which is nice __________________ 1995 318ti Active

I was curious to see if anyone had made their own intake from scratch? I'm thinking of an intake made from one tube and some bends. | | | | | 05-13-2007, 01:58 AM | #12 | | Senior Member Join Date: Aug 2003 Location: cary, nc Posts: 2,259 |
i discuss all the flaws in my write up....i mean i guess they may not be flaws to everyone else but they were things i dont think worked out well with their design and thats why i made my own __________________ 1995 318ti Active

Issues
The first issue I had to decide on was whether a cloth Cosmo Racing air filter (similar to K&N type construction) would adequately protect my engine. After doing several hours of internet research on filter types, I reached the conclusion for myself that yes, it would protect my engine sufficiently and it was safe to continue use. There are many conflicting opinions on this topic so you have to decide for yourself. Another benefit of the Cosmo filter is the size. It is much smaller than the Prelude paper filter and can fit under the hood a lot better.
The Cosmo intake was decent, but in my mind had a few flaws. Firstly, the filter was routed right behind the driver side fog light. Not a big problem, except for the brake duct is in the way. To install, you have to jack up your front tire and remove it. You have to take out the wheel well liner, and remove the brake duct, run the piping down, and attach the filter from the bottom. It is not terribly difficult, but very inconvenient when you need to clean your air filter or check it every so often. I want a system that can easily be removed from the engine bay without taking wheels off.
The Cosmo system was not very secure. It had a securing bracket, but the only place it could really go was off of the side of cruise control mount. Not hard to do, but essentially you are securing the top 3 inches of the intake while the last 20 inches of pipe rattle and shake around at the bottom. I want something a little more solid.
With the filter all the way down by the fog light, hydro locking your engine can be a concern. Though rare, if your splash guard isn’t working, you can leave your entire car stuck if you hit a deep puddle.
The Cosmo intake consists of two pipes which attach together with silicon sleeves and create a round-about S type curve. I am not an expert on fluid dynamics, but I like the idea of making the air travel the least distance. I wanted a straighter path for the air to flow with the least amount of curves. __________________ 1995 318ti Active

I'm debating whether to just buy the Cosmo Racing setup and modify it or if I want to talk to my buddy who has a shop and try making my own. | | | | | |
