Anybody know what this is

[Slugger]

After fitting the Viper to my Cup I found this.

The part marked with the yellow arrow is where one of the standard air feeds connects to. Inside that tubing is a plastic thing which seems to be some sort of valve. The round bit marked with the red arrow has a tube attached to the bottom of it just like the one marked by the green cross. If you put your fingers in and move the valve type thing backwards and forwards you can hear what sound like pumping air.

Whats that all about then?

YOU PUT YOUR FINGER IN IT?!?!?!?!?

i know what it is !!!! its a thingy hehe sorry aint got a clue

Slugger its a valve that controls the hot and cold air feed to your air filter, when the engine is cold the valve closes and opens back up when th engine warms up, to stop the intake iceing up. ive took mine off all together to make room for the cold air feed but it will be going back on in the winter. the noise you can hear is the vacum from the air feed pipe coming from the throttle body as shown in the pic:-

Has anybody removed this air valve? is it clipped in place or is it bolted in? I want to remove it completely (blocking off the vacuum pipe) so that i can use the space for a continuous cold air feed pipe.

I came across this when doing mine.

After a lengthy debate with the reisdent chief engineer over all sorts of things from a limiter (eh? lol) to a cold beer tap we think we narrowed it down to what paul suggested. With no help from renault AT ALL.......they didnt bloody know!

Anyway, it didnt delve in too deep and couldnt see where the hot air pipe came from, but would be to aid a quick warmup due to emissions regulations.

We took ours off totally and detatched the solenoid and kept that pluged in so the computer would think its still there. Never had and problems ever.

Yup, mine was completely removed too, just the solenoid kept and taped up somewhere.

No not really thats why ive took it off all together, but i pluged the other end of the pipe, which i arrowed in the pic. as for putting the standard air box back on, ill wait till winter and see how it runs on the cold mornings or i might just disconect the cold air feed from the filter now fitted.
