Bad news! Looks like our filter is different..

Good news! It looks like an open port filter... its time for me to go to my friend warehouse to see if there's anything ngam.. (he is a retired K&N dealer that still has loads of K&N open port filter lying in his storeroom.. )

There are 2 specs, one Europe and the other US spec drop in's. Our 325i's are based on a conical one which is the europe spec filter. So K&N also has a part no for the Europe spec filter which is conical in shape which is the one both Ken and Speedrat got. I haven't checked on the 2.0 ltr, but Speedworks would know I think.

Yup. I have checked on K&N's website and ours is the conical ones. Yet again, I only checked for the 6-pot, not sure about 4-pot, could be different.

Excuse me... I think the right word is Cylindrical (like piston).. not Conical (like ice cream cone, or Madonna outfit..)..

Not sure if it can fit E90 320i.. E46F, can check for me? Thanks!

I will be checking with my K&N supplier and see if can get better price.

I checked and the stock filter element part numbers are different between the 320i and 325/330i. Both are cylindrical tho .

Orig Filter part no:
320i: 13717532754
325/330i: 13717536006

Ouch... then u guys go ahead.. I wonder how different is a 330i filter.. if I can modified it to fit my 320i, I am sure I will gain more impressive performance improvement..

Grill? Head light? Darn... tonight will do some inspection and check for body damage.. I think I'll be lucky if I can escape with scars..

You da man Calvin. Does this include install or its cash and carry only?

Hehehe... Good question. I would think it includes installation.

K&N ....filter....saves fuel.

This is always the misconception.
A good & clean filter is as good as any filters for "fuel saving" purpose.
K&N filter NEVER claim an increase in fuel economy.

Most people after install K&N, FC worsen because they have the tendency of pushing their engine a little more which they now can.. RFi (Right Foot intelligence) still applies..

But keeping the K&N clean is very important as the oil picks up dirt fast and clog the filter. For a JDM, Speedworks washes and oil your K&N for less then RM9 but our e90 dunno la... so difficult to open (more than 10 screws).. My Avanza K&N can be taken out within 10 sec.. and I wash my K&N in the kitchen using Dynamo and oil it with 2T oil.. religiously every 10k km

Another thing you all need to be careful when using K&N... after the filter element, there located our ultra sensitive air flow sensor. Excess of K&N oil will wet the sensor making it less sensitive.. please do some research on overcoming this.. which I still have no clue except spray it with carborator cleaner.. I have one at home to clean my Volvo 940 air flow sensor and throttle body.

Avanza no such problem because the K&N is seated on top of the throttle.. excess K&N will be sucked directly into the intake manifold and burn in the combustion chamber.. I think my Avanza no air flow sensor also..

This is my air flow sensor..

K&N oil will inevitably coat itself onto the sensor and u can't run a K&N without oiling it. Imagine oiling this sensor... how much sensitivity loss would you suffer? Bear in mind warranty issue..

Ab, thanks! That's very useful info!

AB, does E90 use hot-wire MAFs ?
Most E36s are hot-wire, making us less prone to MAF failure

In normal condition, K&N should last at least 50,000 miles before it need cleaning and re-oil. That mean 80,000 KM. You shouldn't be worry
