Bigger is better imo...but to calculate it correctly, it would help to know the cfm needs of the car to know the cfm capacity needed for the intake/filter.
Best bet is likely a filter right off the maf (non oiled) probably could do about a truck sized filter that way.

Ive always read that having a filter right on the MAF is a bad thing, as the maf need a semi straight flow of air to calculate how much is going into the engine. And putting a filter right on the end disrupts air flow.

Plenty of people have done it. The carbonio is a straight path, VWR, forge, USP's tearduct intake, etc, all do it. I don't see any issue, but idk.

necessary probably not does it shield heat.. probably.

Just added a velocity stack to my cold air intake. I'm going to add a heat shield b/c why not.

Is that the apexi set up?

Almost all of the aftermarket intakes on the market today are undersized in terms of filter element surface area. After calculating the 35lb/min flow rate on my old K04, the filter I chose to use was larger than the one pictured here. Moving to the larger filter increased MAF values substantially.
Clamping on a filter to the MAF housing is fine, the MAF housing has an air straightener in place which will smooth the airflow readings. What you do need to help the air straightener is a 2.5" to 6" velocity stack if you're retaining the stock MAF housing. Then grab a 6" filter. Forward facing or straight facing doesn't matter as per my testing.
Here is what I ran a while back for a 3" intake pipe:

1 x 3.0" Silicone Straight Coupler, Black http://www.siliconeintakes.com/silicone-hose/silicone-turbo-hoses-p-617.html
2 x T-Bolt Clamp for 3.0" Silicone Parts http://www.siliconeintakes.com/t-bo....html?osCsid=49010ddd1b92932e03d81d5371c0616b
The filter comes with a 6” clamp to hold the filter on the velocity stack

Its the unitronic piping with a velocity stack added. The same setup Hyde described, just slightly smaller filter.
Cleaned it up a little bit.

Is that a serious question?
