Hello, nice to see an Alto being modded
Can you elaborate a bit on the 'mile long intake' & the 'pre-filter' bit ( ? ).
By snorkel, do you mean the small U-shaped tube that's connected to the air-box at one end & has a scoop at the other end that's fixed to the cross member on top of the radiator ?

Re-did by adding 2 additional air inlets facing front and right upto where the hood lock is located (cold air).
That works well.
Can you elaborate a bit on how the second aperture 'messed things up' ( ? ).
I presume you lost a bit of low-end torque ( drivability ), but hoping you saw some improvement at higher throttle openings ( ? ).
Asking since I'm planning to replace the intake I have now with the Swift's ( G13BB ) air-box & throttle-body.
It'd be nice if you could post some pics of your engine-bay too.

Trust me, I know it from the horse's mouth, a friend who drives a 3 liter truck and had used a free flow filet and switched back to original because he could 'see' dust in his intake manifold.
True, but not all filters are created equal, the intake I use has an ultra-fine stainless-steel mesh as the filtering element ( it's an oiled one ).
However, to date, haven't noticed any dust of any kind on the downstream side of the filter ( using the same filter for the past 9 years & clean it every 6 months ).

Hi Srini, yes, by snorkel, I mean the long U shaped rubber hose that runs from the airbox to behind the left headlight. In my Alto it is all gone. There is just a little trough left of it to prevent hot air being sucked into the box, about 2 inches long, only!
The second intake messed things because it was a long arrangement G shaped near the firewall and feeding the airbox from bottom. That has long been sealed. Now I have 2 rubber hoses (additional) about 4 inches long each, looking a little upwards and drawing air directly from above the grill (cooler air). I intend to drill 2 more of those and then may be seal of the original air inlet altogether. From experience, unidirectional air flow is better plus when the vehicle is moving, air intakes looking forward get a little forced feed.
I will post images of the engine bay as soon as possible.
I am very much interested in your filter and if it has worked for you for 9 years then may be I can use that in my air box. I am currently also toying with the idea of adding a second air box feeding right before where the MPFI system begins, suggestions welcomed!
