Firstly I was changing my otter switch for a lower temp one and straight away noticed it was a pig to get a spanner on, (mine is on the rad)... done it in the end but I was looking to take the air intake out to give me more room but couldn't seem to pull it through, I took the end off the air filter but it didn't want to move, I noticed there was a couple of cable ties near the middle, but i couldn't see what was stopping it at the end. I'm only curious because I'll be changing it for a smooth bore one soon probably.

The other thing is that I was changing a vacuum hose as as the rubber cap looked perished and noticed there was another tube coming out the back, should there the something on there, if so to go where? its a 2000 plate by the way. See pic

The dizzy vac cannister on old systems used a retard port as well as advance so this is not used now so just gets left off.
Not sure why some cars had this style cannister.

Removing the intake pipe is best done by going in through the front and stretching the pipe out straight as it goes through a tight bend inside the nose cone then pulling it out through the wing via engine bay.
With age that pipe can degrade, if you do remove it stretch it out and you might find it has many pin prick holes in it.
They tend to be in the folds of the pipe so to some extent when pipe is more compressed this possibly keeps it air tight but it’s not ideal especially if it’s in the part running up past the manifold. Drawing in very hot air is not great.
Personally I’d not remove it unless you have a replacement or are prepared to repair ( tape up ) the holes as putting it back through the hole in the wing is a PITA

The smooth bore set up is much better which uses a sleeve where it goes through the wing and the section in the nose cone being pre shaped provides a far less restrictive flow and after having mine on for about 5 years I reckon the thing will last longer than the car. It’s meaty bit of kit.

Brilliant thanks for that, so basically a lot of wriggling, I've heard a smooth bore pipe works better hence the change really, cheers
