Does anyone know what the cover/shield is for attached to the back of the intake manifold? Between the manifold and the firewall.

I always figured it was there to protect the plastic intake manifold from the heat that funnels up through the transmission tunnel from the cats when sitting and idling for a long time in hot weather. No idea, but I'm glad you haven't found any negative effects from removing it. I may remove mine if I ever have to remove the intake manifold again.I think it's for sound deadening. I removed mine when I added 4 corner steam kit to my engine, and that cover got in the way. I haven't noticed anything different with it removed
How long have you had it off?I think it's for sound deadening. I removed mine when I added 4 corner steam kit to my engine, and that cover got in the way. I haven't noticed anything different with it removed
The GM vans do not use that part and their cats are located about the same distance away.I always figured it was there to protect the plastic intake manifold from the heat that funnels up through the transmission tunnel from the cats when sitting and idling for a long time in hot weather.

I learn something new here every day. Good to know. Next time that manifold comes off, that shield is going into the recycling bin.The GM vans do not use that part and their cats are located about the same distance away.

Safe travels on your trip. We're heading out on Saturday for a 4500 mile trip west, staying in Longmont for a few days at the end of August/early September. Gonna hit the West Side Tavern and spend some time with old friends. When we lived in west Old Town, we walked there from our house on Judson several times a week.
And I grew up in Pittsburgh! Great minds…I live in Longmont! I am about to head east, back to Steelton, PA
I think it is there to make removing the oil pressure sensor a real pain in the neck. Maybe some other purpose as well, but I think that is the primary purpose.Does anyone know what the cover/shield is for attached to the back of the intake manifold? Between the manifold and the firewall.
That’s why we left it off!I think it is there to make removing the oil pressure sensor a real pain in the neck. Maybe some other purpose as well, but I think that is the primary purpose.
