So, I'm having air boxes powder coated and the lower half of the box has a grill and under it is a fiber glass insulation (at least it feels like fiber glass). Well, that is not on the parts diagram and I don't know it's purpose.
I'm looking to replace it and will likely just get some fiberglass insulation (hi temp), white.
Does anyone know the purpose and a source? I should have taken a photo but I did not.
I modded my tubi and put some in. The stuff in the tubi was not as heat tolerant. You can see it turns to stone after some good heat.
My understanding of how Fiberglas breaks down in a muffler is because it slowly disintegrates from the constant exhaust pulses beating on it over time. Would this stuff break down the same way? Do you know if it would it be more resistant to this problem than Fiberglas?
