Stock SR20 MAF airfilter setup?

[WheelNut]

So, I just bought a haggard '91 Silvia last week and, well, the car is a bit of a disaster. I removed the stock SR20 that was running all kinds of wrong and dropped in another red top. All the hoses, pipes, and stuff have been messed with and most of the look home made. Anyway, I put a new SR20 stock MAF onto this new engine, but it's just the MAF hanging off the end of the intake tube. There is no airbox or anything. The MAF just has a flat face. What airfilter bolts right onto this MAF? Or is there an adaptor piece that bots onto the MAF first to mount the air filter?

TL;DR: What airfilter for stock SR20 MAF? (preferably something easy to find in the average auto parts store)

Also, does anyone have a picture of an red top install in engine bay with all the hoses hooked up? There are a few hoses that I'm not sure about.

THANKS!

if the car was haggard u need to check if ur sr harness is wired corectly
