Hi,
I put my K&N Indutcion Kit in on Sunday afternoon. It's great, felt a difference straight away! Got rid od my flat spots.

Anyway... Now I have noticed that when I first turn the car on, the radiator fan comes on for a while. Obviously the car isn't hot as it's just been started... Any idea's why it'll be coming on?

When I put the kit in there was a screw to put into the Brown lead that was under the air box, which I did. But, there is also a black lead that was connected next to it... What was I meant to do with that? The K&N instructions don't mention it.

Thanks

P.S What are the brown and black leads for?

the leads that you speak of are vacuum pipes, in the airbox (now replaced with the K&n) theres a thermostatic switch that operates at low temperatures. The black lead from the switch goes to a black thing next to the passenger side headlight. Inside the thingy, it has a flap that alternates between allowing hot/cold air though.

In short, the black lead is no longer needed, therefore you can remove it along with the little "thingy" it connects to.

Hope that makes sense

Ok... I think I get that.

Why did I need to put a screw on the end of the brown one? Was it just to make it air tight?

yup

Grumpy old git going fast downhill rather than downhill fast!!

what does that brown lead do? does it make a difference if you use it without the screw?
