   It's for cold starting,warmth from the manifold is drawn into the throttle body.I take it your putting an induction kit on?

   I want to give up that hose thick and thin hose that goes over the air filter, which can happen if you take out and go? thank you

   It could cause the car to idle roughly,i'd leave it alone as it's there for a reason.

   It's a warm-air intake to stop the single-point injection throttle body from icing up in cold weather. You won't need it in summer but you do for winter. Remove it and you risk breaking down due to body icing causing excessively rich fueling to the point where the engine stops or, worse still, it can cause the throttle to freeze open and an accident.
   
   It's driven by vacuum and a bi-metal strip operated valve which is mounted in the intake that opens the actuator diaphragm to vacuum when the weather gets cold so that it draws heated air from around the exhaust manifold.
   
   Given that it doesn't operate in summer so you get cold air anyway it's better to leave it where it is, helping you not break down or crash due to body icing in the winter months.

   Very much doubt it,pretty sure it works to lower emissions during cold startups,wouldn't explain why other engine of the same size don't have it otherwise.

   shirley popping it into neutral would avoid an accident?

   Don't doubt it. It is 100% what is used for.
   
   It is SINGLE POINT injection, not unlike an electronic carb. Not many engines have single point so that's why you don't see it on many engines.
   
   Guess what? Carb setups had exactly the same thing for exactly the same reason, long before emissions were considered an issue.
   
   I'm old enough to remember working on carburettor-equipped cars and they often iced up without a carb heat. Some of them had a manual adjuster on the air filter with a wing-nut that you loosened and moved to 'Winter' for heat and 'Summer' for cold intake.

   And you've experienced a stuck throttle have you? Popping it into neutral wouldn't stop it revving its tits off will it?
   
   O/P, just do yourself a favour and leave it in place, or ask someone old and educated enough to know what it does and listen to them when they tell you to leave it in place.
   
   look here, on the left is what I'm talking about...

    Fair enough,initially I thought OP was talking about the pulse air injection model fitted to VTS engines above the manifold but then saw the picture and edited my post,I had assumed mistakenly they were for the same purpose,thanks for clearing that up.

    The other end of number 1 goes to the vacuum pipe on the inlet manifold.
    
    In warm weather, if you suck on port 1 it should be blocked (by the bi-metal valve) and in cold weather you should be able to suck through to pipe 2 that operates the flap.

    thanks Chipwizards
    pipe number 1 must be connected behind the throttle , blue jack intro ?

    Probably, yes. Not sure if on the throttle body itself or, more likely on the manifold. It will be a small pipe that sucks air in all the time when the engine is running.

    Are you talking about the black motor for idle control on the throttle body?

    itll stop your car gaining any further speed, allowing you to pull over to the side of the road safely, where you can then turn the engine off completely.
    
    or you could panic and crash into something i suppose.
