172 Ph1 - Idle Control Valve Pipe

[f0xy]

172 ph1 with cable throttle in my mk1, idle control valve on the back of the inlet. The pipe that comes off it, usually goes to the elbow the airbox attaches to, correct?

Im not running this, air filter is in scuttle panel, with a 90* bend, no attachment for this pipe...

Its 'sucking' on idle as I thought it would be, but surely it cant be good to just leave it open, what needs doing....small breather filter over the end?

Will using a small breather affect the idle in any way?

Thanks!

You need to fit one of those small pipercross filters over the end. They do them in halfords for about £11. gaz has one on his as he made his own induction routing.

It definatly needs some sort of filter on it like one of those small breathers.
