Cold Air intake install (with pics)
A few days ago I finally installed a cold air intake Mod for the BMW e34. I don't know what you guys think, but I can get by on one high beam light. I very rarely use it to begin with anyway.
I'm not replacing the air box or installing a pod style fiter. Just increasing the amount of cold air entering the engine. The stock air filer is staying.
The intake now comprises of PVC piping 80mm (the size of the stock air box opening) opening towards 100mm at the front. A speaker grill acts as a screen. The right highbeam light is now gone. The intake is not supported to the light harness (it's not attached to the harness).
To keep the piping together I drilled a small hole and used some computer case screws to hold it together. Two screws in each 3 parts of the intake (where the two pipes join). It cost maybe AUS$50 all up in materials to make. The parts that where most expensive where 80mm to 100mm PVC pipe - $25, 80mm to 80mm (joiner?) - $8 etc.......
The intake seems solidly supported.
Initial testing shows no noticeable difference in power (then again to notice more power you would proably have to create 10% more right?). High beam with only one light works fine at night. Took about 3 – 4 hours in labour.
Attacking / installing / removing the front grills now seem easy. Front clears should be no worries. It's different. I like the look of it.
Anyone know of a better grill (100mm) that I could replace for the speaker grill? To act as a filter for the intake?
What power / torque figures could I expect with this setup and an EAT chip (m30) on 98 RON,.
Please guys, comment and suggestions welcome.
Regards
Kristian
