Third party sealed snorkels for the IG and QM

[KristinaM]

Just had a thought - I know plumbers can put a liner in existing damaged piping. Couldn’t something like this be applied to the inside of the OEM RAI to seal it off in situ?

I’m not convinced this is viable once you take a look at the petrol air induction assembly:

You can see the components of the RAI here:

Granted I’m not a plumbing expert but none of this looks suitable for a sealed liner…

The theory checks out. The pressure drop would increase ever so slightly between the RAI head and the air filter due to the precleaner acting as a restriction. Some 'dirty' air could get pulled in through the inlet duct gaps. About this much maybe? . .

Most would still pass through the precleaner as the path of least resistance and all of it goes across the airbox panel filter.

I happened to watch a good YT on air filters from Donaldson Filters today. It's on The Motor Oil Geek's channel.
The tech is demonstrating the effects of a dirty air filter and how a dirty filter is more effective than a clean filter.
He also restricts the inlet on a test rig to simulate the pressure drop across a dirty filter element. He has to almost completely choke the inlet before a pressure drop registers. This is the same as adding a 'restrictive' cyclone head on top of an RAI. The impact is negligible. Most of the air will still pass through the cyclone instead of getting sucked in through the gaps of the RAI.

I'm no expert, but I have a suspicion that some green garden edging and 2 tubes of sikaflex may not be the most robust solution.

Not a fan of a little bilge pump in the airbox either? Tough crowd here

Although a slight diversion from this topic, does anyone know the purpose of the two feautes marked A and B in the diagram below. In the parts list item A is just part of the Air Filter Box Assembly and is not given any separate classification, and item B seems to be a mysterious protrusion on the Clean Air Duct without any further explanation. I am having trouble understanding their purpose.

I know it was suggested earlier in the thread that A may have a noise suppression function, but it strikes me to be a very odd and unnecessarily complex shape for that.

I think A is a noise suppressor
