Cold Air Feed...how big

[The Kirmanator]

I am replacing my K&N 57i with a standard airbox and replacement filter but seem to have lost the cold air pipe. Can anyone tell me what bore the inlet pipe (Pipe in the bottom right hand corner of the engine bay) is on the valver and if it is the same at the airbox end, its looks slightly bigger??? Is B&Q the best place to go for ducting or are there specialist cold air pipes out there?

Ta.

Get the biggest widest beast u can fit in there. more cold air the better!!

Cant remember exactly cos mines at the paint shop at the moment. But something around 65mm I think. Have you got the airbox and car outside right now? If so, just go and measure the diameters? If youre looking for an easy solution, Halfords only go up to 60mm alu pipe whihc is too small, and B&Q do 100mm extraction/tumble dryer hose which is far too big. If you can find a place that sells Green filters they do a 70mm hose, which will probably go on alright with a couple of jubilee clips. Have you tried a Renault parts desk or scrappy?

halfords ripspeed sell 70mm ducting its about £10.

I measured the bores tonight and they are different sizes....Ive just had a look at the Halfords Ripspeed site but there are no links, it is just a static page??? I take it there are only certain Halfords stores that carry the "Ripspeed" brand?

yeah the ripspeed stores sell 70mm stuff....it wont fit through the standard hole, so i made mine bigger and lost a fog for now! works a treat and the car flys especially at hight speed....

its a bmc cda though not the standard box!
