Filter dimension/size

Is that a serious question?

one is straight and the other is cone shaped. lol

to answer his questions lol

back images are cone in shape front is straight in shape.

I wasn't trying to be a jerk or anything... had he asked if there was a benefit of one over the other, I would've understood asking lol

what are the differences between the straight and a cone filter?

More surface area on cone vs straight, therefore more airflow.

I was referring to difference in terms of performance

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

Cleaned it up a little bit.

Did you connect the the filter directly to a silicone hose?

No, I used a velocity stack.

is the heat shield necessary?

I think the heat shield is overrated IMO. Its a turbo car, the intake temps arent going to drastically affected, especially where the filter placement usually is. I had an Ebay one (with different filter) with no heat shield and now have a BSH true seal and temps didn't change really until after I got an intercooler. Once youre moving the engine bay is filled with cooler air from outside anyway. It does look a lot cooler though with one. I think most of the gains you get are from removing all the restrictions and twists and turns from the factory airbox. I'd mostly be worried if you have a quality air filter and if you retain the factory MAF position.

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:

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

What’s the reason for swapping to a smaller filter in your current setup?

smaller?

smaller?

Srsly you could eat off it, its so CLEAN!

You should see it now, been making some changes over the winter.

Don't leave us hanging. Pics or it didn't happen!

I'm going to take a few more tonight, need to put some things back together after a set of custom headlights.

is this filter size sufficient? https://www.aemintakes.com/search/product.aspx?prod=21-2039dk

is there a performance difference using a velocity stack compared to buying a 3' filter as above?
