Up grade air flow system

Hi everyone
Just wondering has anyone ever upgraded the air flow system on a Suzuki Jimny to a induction kit/cone filter ?  Maybe it will add a small amount of power? If not it will just look cool under the bonnet? 

I have a 2007 Jimny 

Thanks

In my humble experience of these devices I don't believe it will do much to the performance in real terms, but It may sound faster if you can hear the induction over the general Jimny rattle's.
It's not such a good idea if you like wading through water, but if you are road biased and like the look why not, enjoy your Jimny

If anything you'll lose a bit of power. The standard intake picks up cool air from in front of the radiator. A cone filter will get warm air from under the bonnet. Warm air is bad for power.
If you want it for the looks and sound, that's a different matter.

There are definitely gains to be made over the standard setup, which has been made with practicality and low noise in mind rather than performance. I have a couple of spare airboxes, so I might try drilling one. It will still be drawing in air from the same part of the engine bay, albeit 2 inches lower, and it will remove the convoluted mess of pipes behind the wing that Lambert mentions.

you need  x2 57mm o/d 1d elbows some 57mm i/d hose
then route it in front of radiator.......or anywhere you choose 

this removes the convoluted madness giving lots more flow 

 

So I've drilled a 64mm hole in the air box. First impressions are it let's a lot more noise out! Hard to tell if it's improved performance, but the sound alone makes it feel sportier. I've lost my OBD dongle but when I find that I'll do some back to back 3rd gear pulls to see if it makes any difference to performance.

I couldn't find the dongle but I downloaded a performance app and did a couple of 0-100kmh runs. Now, this is not very scientific as it's just an app using phone GPS and I took it fairly easy on the start, but the results do correlate with how it feels. 12 seconds with the hole open, 12.8 second with it taped up. I'd say that's significant and worthwhile improvement for a 5 minute modification!

 

Bear in mind my Jimny has a 1.6 and they always feel a bit strangled at higher rpm compared to the revvy 1.3. Drilling this hole seems to have fixed that.

I still stand by my humble opinion for a Standard Jimny, it's not going to do much.

The air filter system on the Jimny is designed for a 1.3 N/A engine,  the air filter system designed by Suzuki for the 1.6 is different.
What you have is a 1.6 with a Jimny 1.3 air filter system, it's likely it will impede the air flow for the 1.6.  I wouldn't want the original poster to believe it's instantly going to give more performance.

Not being a fun sponge. At my advanced age I've spent plenty of cash on go faster modifications and most didn't 
 

Replacement air boxes are available for as little as £12 on eBay, so there's absolutely no harm in trying! If someone gives it a go on a standard Jimny and shares their findings we will all know forever more.

Agreed.
Happy to be proven wrong and I would be the first drilling holes. Every bhp counts with my caravan on the back 
What is the function of the G3 under wing plumbing, anyone know?
I like to think it's some form of water ingress prevention system, but then it could be for any reason, I simply don't know.
What I do know is Suzuki don't fit anything just for the hell of it, so what's it's function?
 

As far as I can tell it's simply a resonator, to reduce induction noise. There is no element of it that would stop water ingress. At first glance it looks like it's been designed with routing to a snorkel in mind, but the path to the rear section is even more restrictive so that seems unlikely.
