Default Fast 92 issues....can you help fix it ?

this manifold was not a piece of cake install....pulling the shells apart I saw that if you do NOT port it.....you are leaving a few ponys left behind ( spent 2 weeks with a dremel and cartridge rolls ....lots of plastic shavings !! ) the fatness of the rear of the mani interferes with the truck style crossover ( nope....not putting LS6 block offs on mine ) the front snout interfered with the crossover line too !!! little creative bending fixed that......but most important

there is NOTHING to hold the map sensor down!!!

if anyone has auto cad and a 3D printer i am sure something can be whipped up in no time using the one bolt by the sensor as an anchor....some kinda C shaped bracket would work wonders....I am in CAD classes but just not far along yet to accomplish such a task.....so anyone out there that can do it?

Known issue for over a decade, and it's well documented on this board. Either use a new sensor grommet or fabricate something like this:

^^^ great pic.....but where is the story behind it so i can do it too ??

since the fast intakes are not a new thing.....i am sure most people just stick the map sensor in there and forget it......i am kinda **** and the sensor is pretty freekin loose just stuck in the hole like that ( new sensor with a new grommet BTW )

such a common problem .....i think my idea of someone 3D printing a hold down is a winner ( wishes i had a 3D printer )
