Not a performance upgrade but have been toying with the idea of doing this since fitting the ITG.
On the
K1 the ITG filter element (in its enclosure) doesn't seem to get much air. The only air entering that enclosure is via the side vent low down in the engine bay. So I have decided to 'vent' this directly at the filter cone to hopefully maximise the air intake.
Flexible Hose
I purchased 2M of 40mm Revotec flexible air intake hose (having fitted it now 1M would have been more than sufficient).
I chose 40mm as anything bigger would be difficult to attach to the back of the vents.
I used 2 lengths each 40cm long
Inside Engine bay after fitting
Picture collage shows side vent removed (simply remove the 3 screws holding it in and it pops out) and the 2 hoses coming into the engine bay and the final picture with the filter back on.
The two hoses fit snug in the enclosure and therefore did not need to secure them with cable ties or tape but you can do this if you wish
Side Vent (Market with an 'x' where the hoses have been connected with cable ties)
'X' marks the position where I attached the two hoses with cable ties to the side vent. If you look at the top picture you will see that there is essentially 3 places on the vent where you can connect a hose (top/middle/bottom). The bottom section would be difficult to use unless you had smaller pipework as the 40mm will not fit easily between the side vent screw fixings.
Hope this helps if anyone decides to do likewise
Pipework from Demon tweeks btw
