smaller?





This is engine bay porn!

Is this a custom intake kit?
Also do you still use the MAF sensor or is it just plugged?

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



Do you happen to have a picture of this setup?
The standard MAF housing is 2.5 or 3 inch?
