What is this part?
 

94 940 2.3L non-turbo.

Need to find out what this part is called and a good place to get it from.

Thanks.

Pic attached.

It's something related to the intake and/or exhaust, as a hose leads from the air box and then two metal pipes lead down toward what I presume is the intake manifold.

I'm referring to the rubber pipe...

thats the ''pulse-air" system on a B230FD engine. there are two one-way valves on the exhaust side that fail, then hot exhaust gasses burn out the tubes.

the "F" tube is volvo PN 1266666
the 2 one way valves are Volvo 3507332 (order 2).

you can order these at any volvo dealer's parts counter, or one of the online volvo dealer parts stores (I use VolvoPartsWebstore.com and/or TascaParts.com ... the latter is cheaper, the former has a better online catalog and better automatic status notification and usually ships faster, tasca is cheaper, but a black hole until the parts mysteriously arrive).

Thanks
 

I actually found a similar question you answered after posting this via Google. Thank you for clearing this up.

note, btw, that if you live in an area where hey don't do any smog inspections, you *could* remove the pipes from the under exhaust manifold, and plug up the openings. you'd need to make some plugs the same diameter as the ends of the tubes, that would be held in place by the existing clips/clamps. ditto, plug up the other end of the hose that goes to the intake manifold, and disconnect the Pulseair vacuum actuator thingie.

it will have ZERO effect on engine performance, pulseair just injects some fresh air into the exhaust gases so the catalytic converter can do a better job.
