Do I really need this thing? (1 Viewer)

I was swapping the valve cover on my 60 and when I went to put the airbox back on I noticed this thing hanging by a thread or what looked to be asbestos fabric on the exhaust manifold. I assume it attaches to the flex pipe going to the HIC controled door in the aircleaner.....can I live without it....or should I replace it? Looks like a pain to put back.

Looks like your heat riser but I'll have to allow someone with more knowledge than me answer whether or not you need it.

That piece diverts warm air around th exhaust manifold up through the pre-heater hose into the air cleaner. Is it necessary? Not really, but it helps warm things up quicker.

Not sure how it is where you are, but over here in the Peoples Republic of California, I failed smog because the hose that goes between that thing and the intake was missing.

Well that and I was a "gross polluter" But I inittialy failed the visiaul due to that stupid little elbow thingy. Sweet

Not needed. Just keep the preheat hose in the general vicinity of the exhaust manifold. A smogged 2F gives off plenty of heat to warm the air underhood.
