New Gen4 Snorkel

I know it has been mentioned before but the gen4 has this "empty" box in the inlet pipe next to the air box. As it is empty and is called the "resonator no3." in the parts manual, I would suggest you explore further in this area as the bravo snorkel removes this. ( I looked for resonator no1 or 2 but nothing is listed)

I would reckon you could add it back in.

Tell a lie

There is:

Resonator, No 3 - Jimny
Resonator, No 2 - Grand Vitara
Resonator, No 1 - Liana

All positioned in similar positions just in front of the airbox

I did look at the "empty box" and think it must be something like that. But trying to fit that withing the flexi-pipe and getting a good seal will be nigh impposible. If the pipe can be replaced with something solid, the you will have a much better chance.

Just writing an email to Bravo now.

Just catching up on this thread, sadly have been ill since Christmas Eve...

I did try reversing the head on my snorkel, as you can see you can't quite fully reverse it, but it does work fine like this.

It has no impact to the resonation noise being made, however if you open the window and induce the noise you can clearly hear it is induction noise, with the window up it does however sound far more fog horn and intense like.





In terms of the cause. I suspect this engine must have a harmonic trait as the factory ducting contains a baffle/resonator box (as Martin lists above). The tube also has some hole in it too, which must be there for harmonic tuning.




A test I'd like to run is to have no ducting to the airbox at and see what results.


My hunch however, the flexible ducting on the Bravo snorkel is not the issue or source. I suspect it must fully be the internal chamber of the snorkel, which is either amplifying an existing noise or more than likely producing the noise and amplifying it. I will await Bravo's reply before attempting any real fix. As I do not see how it cannot be an issue on every single snorkel they have sold for the Gen 4 Jimny.

Those holes are the water drains according to the Brazilian snorkel instructions. The Brazilian snorkel kit provides a blanking plate for those holes and a duck billed drain valve so that the entire tube is sealed

Interesting, although I'd suggest that maybe they are multifunctional. But I can't see their prime function being water drain holes, as they'd need to be on the lowest point or in some kind of vee. Under moving airflow water would be unlikely to collect or drip out of the holes as air will be being sucked in through them.

As they are located next to a tuning baffle/resonator, I'd guess they are very much part of the harmonic tuning. Bit like the finger holes on a recorder or Irish whistle.
