Need diesel intake silencer for bobcat skid steer loader
(OP)
I'm new to this forum. I have a bobcat or more correctly a skid steer loader made by New Holland with a 3 cyl. Izuzu turbo diesel. The intake is only a few inches behind the operator's seat. It is not muffled. I'd like to know if there are any off-the-shelf silencers that I could install at the intake opening (approx. 3 - 3-1/2"), pricing and where to get them. The engine is approx. 78 hp, turbocharged, 3 cyl. and runs wide open at approx. 2600 rpm. Any ideas?

Maybe somebody makes a silencer; I don't know. If not, you could make a tuned pipe sort of thing, given the fixed operating speed.
It might be simpler (though not nearly as effective) to erect a sound- absorbing barrier between engine and driver.

A correctly designed air filter should be a moderately effective silencer.
A plenum in the added on pipe or duct, especially if the inlet and outlet of the plenum are in different planes.

Isn't there something that would affix to the open end of the intake pipe?

Remember that Diesels take in a lot more air than gasoline engines of equivalent size, because they're always running with the throttle wide open, so you need a big air cleaner. I'd start with a hot rod air cleaner for a 350 Chevy, just because they're common.
The material of the plenum should be thick, and relatively massive. Many plies of fiberglass would be okay.
