I needed about .6 to .7 metres on my sprint

Yes I have seen that but I believe the +2 needs quite a bit longer ducting than a Sprint.

Probably true, I can’t say. What I can say is though that 90mm as opposed to 3.5inches worked well for me - made it easier to attach to air filter box and air box.

I measure mine at ~60cm and a cut off of 40cm. I am not using the standard filter housing in the nose but a cone that is mounted closer.

I think 1m will be long enough.

Thanks for that.
That helps a lot and just what I needed to know.

If you want more the ask the usual suspects for a longer length.
I'm pretty sure they buy rolls and cut to suit.

Well having my cheapskate hat on I was hoping to get some from ebay where it is much cheaper (usually China) they only sell pre-cut 1 metre lengths which I have not been convinced will be long enough for a +2. Hence my question.

I'll try remember to dig out the hose that came with my car and measure it tomorrow. Can't be 100% it's original and correct but another data point.

I used silicone 'brake duct' type tubing, which seems great stuff. Fits well, is durable, and even where it gets bendy the inside remains relatively smooth compared to corrugated-type duct, which might be good for free-er airflow. I got a 6' length from Pegasus Racing. They have many diameters and I used a smaller size for the ducts to the dashboard vents.

If you can live with self colour you can buy 1m length that extends to 3m if required.
Or I did see 2m length for £6.99.
Or is that too 'cheapskate'?

I had a look in my attic/garage for it but can't find it. Wondering if I got rid of it as way to dirty to use again.

Ok, Thanks for looking anyway.
I have now been told elsewhere that for a +2 with standard airbox I need 44inches of trucking. So a metre length from ebay is not going to be long enough.
