This is what it looks like, used the OE intake, adapted the diameters. Drilled a hole on the adapter for the sensor, and another on the resonator box for the vacuum line that was attached to the original airbox. Easy as pie, since pie takes 4 hours to make.
Its a cromulent replacement if I do say. and if it holds up for a bit and I trust it I'll make the parts list and a video or something. If you're into noise, it makes it. You can REALLY hear this thing breathe, sounds like it's had a cord wrapped round it's neck for nearly 3 decades and is finally allowed to take a deep breath. The sound in the cab under acceleration is a deep grumbly noise with an induction whine undertone. It's very noticeable but fades to ambient levels in the cab while driving at a steady speed.
As far as power goes, like the other people who've done this modification, there's DEFINITELY something there. Not much but it's unmistakable. not a placebo effect. It doesn't feel like the 10%+ some people have preached on theirs, but I'm also sucking in air from the engine bay too.
On the topic of Engine bay air, I was a bit worried too. However, after driving hard for a bit to get things hot I parked and opened the hood, intake was still cool all the way up past the throttle body. I think it's still able to pull air from the grille and around the headlights like normal so no worries there.
Only thing left is to make a proper mount for it, you may have noticed the bungee cord.
