It's not worth the time and effort, and makes pulling the filter a little harder. Definatly a NO-NO with a clear lid, as they are even MORE prone to cracking.

It's 3" in/out, and its 4" long. Fernco part number is 1056-33. And here's a picture of it, you can see it in the background

LOL! so basically you are saying **** it?
I have a fernco but I trimmed it and used a hair dryer to make it fit. It was bothering me that it didnt go flush against the MAF at first. now it does.

Is the 3x3 Fernco big enough to fit a 90mm TB and 85mm MAF?
I tried to get a Fernco Sunday doing my 90/90 install. The 4x4 was too big, they didn't have a 3x3 in stock, the 4x3 looked like it was a hair big for the TB (4" end) but not near as oversized as the 4x4.
