This is my first post, yay

Anyway probably some dumb questions as it is late and I had a few red wines.

Under the Cinq airbox there is a sensor or some sorts, the wire goes to the cold/warm airfeed. What is this sensor called? To my knowledge it is not a MAF, if that is even used on a Cinq? I think the IAT/MAF is on the TB?

When adding an induction pipe + filter I can just ditch this sensor as its only purpose is to open the valve when running cold?

Also I haven't looked at the pipe coming from the manifold, but I take it that this connection is just closed and not open? Probably answering my own question, but taking air straight from the manifold deprived of oxigen sounds completely pointless to me to warm up the engine...

its not a sensor it mixes the hot and cool air like a thermostat for cold starts i think you don't need it...

But there is some sort of sensor in the bottom of the airbox, it is pinkish and probably gay so I will remove it.

Will post a picture when I can.

i know what you are on about its not a sensor it opens a flap in the air box...

Picture would help. That would take away any speculation.

It's a mechanical vacuum/Temperature controller.
When the intake air is cold, the valve is open and allows the intake to create a vacuum that activates a control flap. This allows warm air picked up from the manifold to mix with the cold in the pipework. It's good for cold temperature running but the design is biased toward carburettor type fuel systems to stop ice plugging on the jet. However, the injector nozzle could ice up if subjected to low temperatures, being in a similar place to a jet on a carburettor type system.

It was broken on my 899 Cinq, so I removed the flap mechanism and blocked the hot air feed.
No problem starting or running even on the odd extreme winter morning.

So no, you don't need it.

It is situationed like this:

TB > wire > airbox > pinkthing > wire > hot/cold valve

Can't make a picture as my Cinq is not on my driveway atm and Google has no pictures :s


Anyway if you unclick the filterfront, it sits there at the rightside on the bottom.

Remove and it with hammer until dead!!!!


its pointless, I removed on my Cinq and never had any issues but there again, I converted to MPi fairly quickly lol
