As looking for the "perfect" 180 degree reversing duct for a cone filter I came across the k&n site just to see this. Anyone know this? Must be cheaper that anything...

A member of the forum (SPS-SI) had an inlet he was developing using a BMC carbon shrouded inlet and 2 90deg Samco hoses. Looked sweet but having priced it up it makes the Dahlbak system look cheap at £190! With decent ducting and mounting I can't think of much better though as it's fully shielded and those filters give good flow AFAIK. If combined with a 180deg 80mm diameter metal pipe, or larger, I think it may be an option but would cost around £250 with a heat shield! I'll contact Si and see how he did it.
Was looking yesterday at heatshield options and will be having a go in the new year. Looking at mounting it to the strut brace, original airbox bolt and possibly a bolt at the front by the headlamps. Will attempt to make it out of sheet Ally as this should be easier to work with for a prototype. Inlet ducting will go next to the original scoop by the headlamp. This could then be used with any cone filter and may even present a group purchase option if it's any good and I can get it drawn up on CAD at work (or just by hand).
If anyone on the forum can get 180deg bent pipework made out of up to 100mm pipe then keep us informed!Cheers'en, AndyC

I personally would rather fancy a single piece 180 degree, rotated nicely, no inner edges to minimize turbulence and lightweight. We'll find it.Originally posted by JamoWasn't 2 90 deg drain pipe bends considered to be the answer to cheap 180 deg bends?Gabor

FWIW - The Dahlback pipe looks like 180 from a distance but there is a skew in it so that the fattest part of the air filter does not sit directlt below the MAF.

Here's a picture of SPS-Si's pipework.
