I'm sure it's been covered many times before but a quick post for your thoughts on:
K&N
Pipercross
Green Cotton
OEM
panel filters for my 320i (with a Mild chip). Which one should I go for? Aware that it won't make that much of a difference but it needs a change anyway.
Cheers
Air Filters

personally verde, id say OEM filter, K & N may be fractionally better flow but its down to letting more air through so what else is getting through?!
OEM filter box and OEM filter panel would be best IMO, its not like BMw spent many many hours designing it or anything

Agreed with the above, OEM box, but with a K&N Filter.
BMW spent a lot of money in R&D, as have K&N, best of both worlds and if i recall it's been proven by rolling road on one car doing back to back tests against OEM intake with regular filter, K&N and Cone type.
Found the OEM both was good, with K&N filter was improved, but the cone actually was worse than retaining the OEM intake system.

Usually run with a high power fan in front of the car to provide airflow to both intake and the radiator.
Usually cone filters suffer from heat soak and suck hot air from the engine bay, result = power loss!
BMW knew what they were doing

Thats handy because thats what i just gone and ordered myself.Chris_B86 wrote:No issues with my Pipercross, and it's cleanable, never have to buy a new one again
I was panicing a bit just reading this when everyone was sayin k and n, but then i saw this. Good to know you havent had any problems with yours it gives me a bit of piece mind. At least i wont the only one with pipercross panel filter.
Purely previous experience and friends testimonies. I had the Pipercros Viper Cold Air Induction on a previous car and it was fantastic, but I wanted to keep things OEM under the bonnet so chose the Pipercross panel filter and have no complaintsRich2388 wrote:Chris, what made you choose pipercross over k and n?
