Restrictor In Vacuum Hose

[Spence_R32]

So most of my vacuum hoses are slitting so i ordered a new hose kit.

Just in the middle of fitting it now. When i pulled one hose off, there is a restrictor in it. Just wondering what its for and if it needs to be there?

Either way im glad it was. On the turbo side of the restrictor, there was a bit of wire brush that has been snapped of and stuck in there

Was it the hose running to the wastegate actuator?

If so - a restrictor in that line is often to help with spiking issues by controlling/dampening the flow of air to the actuator diaphragm.

If its in the line leading off the solenoid, it's there to artificially increase boost.

Either way, you can get rid of it and be better off - just watch your boost pressure after you're done to make sure it's hitting the same levels (as in not higher than target)

OK cool. Cheers for that. ill take it out and ill keep an eye on my boost.

Wait, in the pic it looks like its the pcv line off the rocker?

Mine has a wire brush in it too I assumed it was to help baffle the oil coming out of the covers?

Oh ok. Ive never seen anything like that. I would have thought it would be on the rocker side of that restrictor, not the intake side. Well ill put it back in then.
