Stock airbox set up

[Shimian]

Looking to remove my resonator from the airbox. Planning to keep the stock air box and put some sort of piping after the bottom part of the airbox routed to somewhere down the front.
Something like this

My question is, which part does the air sucking? Just wondering if i do this set up, will air get sucked in mcuh better than the stock setup (with resonator)?
OR
Should i just remove the resonator and keep the piping so it would look something like this

Any suggestions or parts to buy to assist with my new set up?

I have ducting from the stock airbox to the under the front bar (sits on the plastic splash) and sucks air through the front mesh. (aftermarket filter in box)

I can't tell you what stock is like, cause my car has always had this, however just keep in mind if your car's low and your putting ducting you tend to pick up a lot of dirt and stuff.... I usually end up getting out the vacuum to get some of the dirt out of the ducting lol)

[Shimian]

What if i route the pipe not too low to the ground? I mean, it has to be better than the stock setup? As you can see the intake pipe is sitting inside the engine bay sucking hot air.

[Spunkymonkey]

if its not encased then it will be worse off...I've had a similar cai before which just sucked in hot air and made a lot of noise....

so if you are going to do anything its best to try and fit it into the stock box, or have a box so its not sucking in hot air....

I can't really say whether its better than stock..more than likely yes....

I have noticed differences between using different air filters.

[Shimian]

What about something like this? I install it after the airbox and aim it towards the bottom?

OR

What can you recommend from Simota or other brands?

Thanks

[Spunkymonkey]

it looks ok, but sorry I really can't comment on all the brands because I haven't used them. I'm using a simota aluminimum air filter though....probably best to wait for some others to reply.

[Shimian]

Not really after a particular brand but to get an idea of what i can use for my setup. Looked through the whole simota website and that product i have linked is the closest to a boxed intake. I was thinking of putting a CAI or an SRI to the bottom of the stock airbox but i dont know if that will work. Whether it will suck cold air and give some improvements or atleast better than with the resonator. And sound wise will probably be LOUD?

[Spunkymonkey]

mine isn't loud, because its just a filter in the stock box, with air con type ducting to the front bar....so the filter is totally covered, so its only a slight increase in noise. Having an air filter in the engine bay not covered by a box is what's really noisy

Here's what I've done and I'm very happy with the result. I wanted to free up the top end without losing the cold air when standing still.
The pics below show my stock airbox with the original inlet cut out completely (also resonator is removed), I fabricated a bracket out of galvanised aluminium, fixed it on with pop-rivets, cut a 100mm hole to fit a 100mm stainless steel tube (from exhaust shop) angled downwards, and I used roof and gutter silicone to hold it very firmly, then gave it a coat of matt black paint to hide it.
I bought a 100mm (4 inch) diameter x 1m long reinforced flexible rubber tube (from Clark Rubber). I used a stainless steel clamp to hold it on to the box, routed the tube downwards, under the chassis rail and then forward a little, and cut it about 200mm short of the parker light. I fastened it in place with cable ties.
How does it sound? Much quieter that an SRI pod filter, but still has a refined deep roar.
Hope this helps.

[Shimian]

Sweet, so will this procedure work?:

remove everything from bottom of stock airbox.


buy a rubber tube from clark rubber


buy a stainless steel clamp to hold rubber tube to the bottom of stock airbox


route the rubber tube to somewhere where cold air would be sucked in


secure the rubber tube


Wallah? Do I need to put anything at the end of the rubber tube incase leaves or crap gets sucked in?

[T-onedc2]

yep that should work fine, the only real challenge once the resonator is removed will be making the tube fit the airbox.
I don't put anything over the end to stop leaves, all I find in the box now is the occasional tiny pebble but it won't get past the filter.

[Shimian]

My other option would be to remove the resonator only leaving the piping that connects to the resonator. (as shown in the above diagram).
Will this option work too?

[T-onedc2]

You can try it, I tried it first too but found it was slightly more free revving after I made the final changes, also it sounded better :thumbsup:

[Spunkymonkey]

mine is very similar...except I have cable ties holding the ducting in place...the previous owner had made a couple of small holes to put cable ties through

[Shimian]

Anyone tried fitting a manufactured part to the bottom of the stock airbox? If so, what did you use (brand,model)?

[danny_2132]

hey does the stock airbox come stock with a pipe at the bottom of it that goes down?

cause i bought my car with it

[T-onedc2]

The pipe below is fixed inside the resonator behind the guard and the airbox just slips over it.
So if you're buying an airbox from anywhere it won't have the downpipe included.

i removed the resonator on my stock intake last week and found the throttle to be more responsive plus it sounds great past 3.5k rpms! in effect its a SRI but with the benefits of having the airbox there.

[danny_2132]

how do i know if the resonator is still in there?

and if it is in there how do i take it out??

thanx

[T-onedc2]

If the factory moulded plastic pipe from the airbox which runs down into the guard then it's still there, the resonator box holds this pipe in place.
