So today i was fiddling around under the bonnet, decided to remove my cold air intake and just leave the air box with the oval shaped opening. Took it for a drive and it gave heaps more grunt and sounded heaps beefier.

My question is, what can i do to make this a permanent thing? im assuming its not a good idea to leave that oval shaped opening because the filter is straight there.

any answers greatly appreciated.

So... you put the panel filter back in with the box minus the snorkel that draws in air from the bonnet?

If that's the case and you've left the "oval shaped" hole from the box it really doesn't matter.

As long as you have some sort of filter there it's fine, although there's no reason why you wouldn't put the snorkel on since you're sucking in hot engine bay air without it.

Put the snorkel back on, it helps alot.

yes that is correct

Sounds like it too me.

I would bet you $8.64 on the fact that what you felt, performance wise, was in fact result of a placebo effect. If your keen to keep the sound, invest in a K and N oval pod filter. Just up too you really.

Actually going back to the panel filter is known to give more down low. It seems that putting on the CAI creates a flat spot in acceleration.

That being said, I'm putting mine back on cause it sounds sick.

And Rush, read my first editted post. In short, put the snorkel on.

yeh i understand what your saying dingers,

I guess i drove our 380 on the weekend, and that had a real grunt to it thru 1st and 2nd, and after taking the snorkel off it seemd to produce that same grunt and actually felt like i was driving a 380.

Having a pod does create a flat spot at about 4500 rpm, but its a magna, its not fast anyway. Might as well make it sound nice.

I've been running with no snorkel to the air box for 18+ months now. I did performance testing with and without the factory snorkel on a warm 26 C night at WSID drag races and the times were identical.

IMO - the hot air sucked in doesn't make much difference on a stock motor. If you had a tuned ECU and it was tuned on the edge, definitely ensure you have coldest air possible getting in, but otherwise you may just want to put the snorkel on when it's over 30C during the day (stuck in traffic on a 40C day, I recorded air intake temps of 70C on a previous car running a pod filter behind the headlight but still in the engine bay.

I will agree with Illestmagna that the gain in performance could well be a placebo effect. I found with mine the exhaust tone became beefier and the little bit of induction noise is a welcome addition. :)

Have fun - it's cooler weather time, so you'd be lucky to get air intake temps over 40 C IMO which means more fun without the noise restricting snorkel or CAI.

Yeh you pretty much summed it up! the Exhaust tone is much beefier. I might try running no snorkler for a bit, but might actually put a stocking or something over the oval shaped whole on the air box to try and stop anything getting in there. :)

One Horse per degree, folks. That's what you gain (so I'm told - in reality, from my own Dyno experience on my "weekend" Mitsu, I gained about half a horse per degree C, measured at the intake manifold). Now, if you had a more free-flowing snorkel...... you'd have the best of both worlds, right???

You do have a filter there right..?

Like a panel filter or something..?

You're not talking about the honeycomb on the MAF, are you..?

Nah, he' talking about the little oval inlet that's left over when you take off the snorkel. The mod itself doesn't do too much. The car sucks in a bit more hot air, so in summer you're going to be worse off.

The extra "performance" that you're getting is only because you're driving it harder to hear the noise. If anything it takes a bit of power away from the car.

It's fine to leave it off, in summer I would saying put it back on so your car doesn't have a massive power loss once you've been sitting at traffic lights for a couple of minutes :P

Why dont you just run a duct from the oval shaped opening down to front bumper (like many people here), that way you eliminate hot air problem yet keeping unrestricted air access. But you will find thats its mostly placebo effect anyhow, but at the end its a really cheap mod to do so why NOT

Ahhhhh.. Just checking!

Get a POD & MAF Adaptor..
Cut out a paper filter..
Put your pod IN the box and listen to the induction noise!

Hey guys has anyone used those cotton pods with fixing that just bolt on to our MAF (no adapter needed) sensor forgot the brand (its got opening that precisely replicates our maf oval shape), if yes do the fit in our air box?

I've been running without the intake snorkel for over a year for the simple reason that my battery is too big to fit the stock snorkel on and I've been too busy to get something else made up for it. Power is unchanged, if anything it has increased my fuel economy but I can't confirm that, but 13l/100 is really starting to piss me off.

I had the intake snorkel off when i was doing some engine work, and found when the car starts to warm up and the fan goes on, the hot fan air goes straight into the intake and causes the car to run really bad. It not as bad when you run on petrol, but if your on gas, as soon as the fan goes on the car wants to stall. so i was say that having it off is not doing any good. like some have suggested, probably if you want to do anything, run a duct down to the front bumper.

I've always thought but not tested that when doing drag runs, etc "hot air" wouldn't be much of an issue due to the fact you are sucking so much air in.

I figure it'd just confuse and pointlessly warm up your poor engine sitting at traffic lights, and I guess on initial take off.

To the OP, just put the snorkel back on lol.

If you want sick induction noise, put a SCA 25 dollar pod on a MAF adapter, buy Welch plugs and remove the resonators on the intake hose and shove them into the holes and use the old clamps to clamp them in. Once you've done that cut out the back of the airbox just enough and sand down the ridges on the top of the box from the inside so you can fit the pod filter into the box.

Put foot down, sound like W16 Quad Turbo.

If you can't be bothered, just put the snorkel on, it won't do anything but improve things.

I have to disagree with dingers on that one, a pod on a 3ltr sounds like crap when comparing to just a snorkel removal, ive tried both on mine and with a pod the engine sounds like its being rev'ed to the shit house ,does'nt sound good at all in my opinion, where as with a snorkel removal you will get a beefier more solid sounding rumble, my advice save your $33 buying a filter and adaptor i recon you will regret it, dont plug up the resonators , you will lose initial low down oompff.

i have to say i do notice a performance decrease with the snorkel off, especially on take off after waiting at the lights, but if you feel like being a hoon its well worth it, the look on peoples face's when you plant it at 80kph and do a fly by is priceless.

Taking off the resonators results in decrease in low down torque? =\
I know this has been covered before, can't remember the outcome though.

Don't see how removing resonators can affect anything since they're air tight chambers that are rigid.

Someone shed some light?

Dont know if it loses torque as a figure, but dont they hold a reserve of air for when the peddle is planted , rather than drawing all the air from the inlet on the cai, it draws from the reserves initaly as well as the inlet, to give a larger volume of air? well that was my understanding in relation to previous threads on this forum, it has other uses as well , but its the weekend and i aint studying....

edit: if the resonators are air tight whats the point in having them in the engine bay? to fill the gaps?
can't remember if this is true or not from the last time i removed them to have a look.

Well I assumed the resonators were there to control noise, thus the name.

In theory it'd impossible to suck air out of them since the chamber is air tight and can't be compressed or changed.

Resonators do not effect power at all. They are noise control devices as the Magna intake is rather loud in "straight" form.

Why would you regret spending $35 on a WASHABLE cotton filter when the stock throw-out paper filter costs $47?

As for the pod, it needs to be properly enclosed. A modified stock airbox containing a pod gives a really deep loud hammering induction noise. Anybody who heard Zahrim's old TE will be able to tell you this.

Removing the snorkel is ****ing STUPID. It is there to suck in COLD air, hot air = worse fuel eco, less power. Simple math really. Colder air is denser air, denser air is leaner AFR, leaner AFR is more power, better fuel eco.

Im no expert but does this link relate to our topic?

http://planetsoarer.com/resonator/resonator.html

from what i gather it has two purposes ,firstly sound, secondly volumetric efficiency...
the two websites listed from dingers and i contradict each other.

and LIFE i did'nt think we were talking about a washable cotton filter, i was reffering to a $25 sca filter that dingers mentioned , which i pressumed were disposable?

Really this sums it up, well said.

Nope, SCA are washable cotton.

Nope, SCA are washable cotton.

well ill be... in conclusion washable sca filters are a good choice, removing resonators isnt.....
