Here is mine. Of course the only pic I could find it shifted in haha Oh well.

I think im on the right track. Need some denser foam though. This fits nicely but needs a little bit more rigidity. The prototype gasket was the best I could do at midnight and sacrificing an old gun case. :thumbsup:

that seems to work really well. I think you are on to something there.

Nicely done, especially at mid-night...:rotfl:... The real test will be a road trip and see if it shifts...:thumbsup:

I doubt it will do much shifting. the only reason mine does is everything is smashed in that box with the spacer installed. Nothing lines up like it should anymore :rotfl:

What spacer do you have installed? Is it for the air filter?:confused:

It is an Airaid Throttle body spacer off a 4.2 envoy/trailblazer. You can barely see it in the picture. It is red. I got it for super cheap off this forum from a member. Idk if it does anything other than make noise though :rotfl:

i need to get a new filter...one that would fit all the way in the fender well of a 3800... any ideas

I couldn't tell you:confused: maybe make a thread on it and some 3800 guys could help you out that have made FWIs before. :thumbsup:
