Nice1 joe! Iv got all the bits to do mine but ill be just routing it straight to my k&n cone

Be easy then, i had to slice the pipe to get it to shape on the airbox.

I think this makes far more sense than 100 sovs for the pipe

Is there any proven empirical benefit yet ? Has anyone actually mapped their car on anything stage 1 and less and seen any measurable benefit on this ?

From what I have read here its for the "big wave surfers" lol, those seeking over 200bhp,

however if you are mapped to below that you just spunked £100 for a bigger pipe for drawing extra air you don't actually have the capacity for bringing into the engine or something?

A bit like having a bigger pipe for your vacuum cleaner to suck the air in but not a bigger wattage of motor, something like that seems a good enough analogy for me

From the autospeed articles on the Roomster, the standard intake pipe(s) can be improved upon. Though they're far from rubbish to start with, even if they look a tad weedy. Biggest actual restriction is probably the meshing in the MAF pipe followed by the anti-shudder valve.

Nothing gets sucked through the pipe its just air directed from the out side, so a biger pipe and mouth can carry more air to the air filter. But i have saved about 80 quid here so its all good

So you don't intend to put a Henry the Hoover under the bonnet? Lol

Keep away from deep puddles

The duct isnt flush it has about an inch along the bottom and a drainage hole at the lowest point of the pipe.
