Laneza,
My car is an e36 328i, reason the engine bay looks a bit different is that i am running the e36 325i intake manifold. it should be easy for anybody to copy this design for any type of car. Just as long as you can block off a section of the car to make sure that what ever filter you choose is properly protected, you should be fine. it's very important to make sure that you have a heat shield that is insulated. I've seen just metal plates being used and this is not ideal as the heat will still pass through to the filter. what type of filter you use is totally up to you. In my opinion, there will not be much of a diff between brands. I would recommend a K&N drop in panel with the stock air box if your car is mostly stock. Also, i prefer my K&N Cone to my Pipercross Venom, the K&N has more filter area than it and with the heat shield it keeps things much cooler than the metal case the Pipercross comes with.
Dolceaddict,
Filter came as part of a kit which i ordered from e36coupe.com. You can get it made yourself for much cheaper here, but i didn't want to go through the hassle of DIY. But having looked at it, i am sure you can get it done yourself much much cheaper than the 160 pounds i paid.
The kit is fine as it comes, but i did get the intake pipe ceramic coated as additional insurance and added additional heatproofing to the wheel well, and back of the heat shield.
Cheers.
