Airflow straighteners.

3" yeah, that's exactly what I'm after. I'll definitely have that off you, I'm happy to pay full value for it.

Drop me a Facebook message mate, I'll let you know when I'll be around for you to collect it.

Looks similar to what we use to straighten flow for measurement purposes. But will this really help with idle? Would have thought only make a big difference at high revs when moving

Probably better to just use a high quality silicone hose. A lot of OEM ones are not smooth on the inside which is what causes the "problem".

You might get a more stable reading with that honeycomb thing, but it will restrict the flow.
