You can use the large MB and put K&N filters in the box. That with the 74mm TB, and 3" tubes going from the box to outside the rad wall will give you what you want. It still not cheap. Here's a pic of what it would look like. The nice thing about NW is that is all packaged for you. I had to source all the components separately.
Now this is what I'm talking about! I have spent the night pricing up options. Volant makes a fab kit for about $200 with plastic/carbon parts that look like they would work well. Airraid makes a fab kit too I think. Weapon R would be $200 a side.
The V8 box in this pic with parts looks like it would more expensive than the NW kit.
Looks like the Needs Wings Single is going to be the most logical option for the $ and time involved. If needs wings sold the MAF and coupler together by themselves, the rest would be easy! Someone please sell me their NW single!
