I intend to take off the stock air inlet to the filter box and replace it with something which isnt blocked by the bonnet..however under the standard air inlet is a black flattened egg shaped gizmo which does not seem to be attached to sensors or wires or anything..what is its purpose?:confused:

It's a resonator. It's designed to cancel out rumbling in the intake caused by pressure waves bouncing around. If you take all the resonators out, your car will sound a bit like a V8 under load.

They are there for a reason beyond blocking a "v8 sound".

The resonators have been discussed many times on this forum. In my opinion the snorkel is what cancells out the sound burble. The resonators are there to increase the intake air flow at various rpm bands and thus increase the torque at these rpms.
Leave them on. I know this is contrary to what some others believe.
Cheers.

I have also done this mod, noticed no difference anywhere in power or response, but the car is louder when the foot goes down.

just run a search for more threads

i was looking at the standard intake the other day. Everyone says that the rubber seal under the bonnet blocks the the intake snorkel, but infact the seal is deflected around the snorkel so that it sits ontop of the upper lip and does not cover the opening at all. Not sure if it is just a TJ thing though?

It's the same for all models. People tell themselves the rubber seal blocks off the intake as an excuse to use drainage pipe in their engine bays.

my dads good m8s with a man named Steve Martin, he worked at tonsley mitsies. he worked mainly on the air intake and air intake calibrations, and he was round the otherday and i was showing him me pod filter in ezboy box and sh*t and he knoticed id taken off the resonators. and i asked if it was good or bad that i took em off and he said that " it dont matter,They are just to reduce intake noise":badgrin:

There is another seal on the leading edge of the bonnet that seals against the grill. This is the one people are talking about, at least all the Magna I have seen have had this.

maybe pre tj but not on my tj...

i wouldnt waste time with cai....

i have it and i''ll swap for a stock intake if your nearby

Possiblly, I have only really looked at TFs.

Don't tell me you have that super duper awesome sprintex CAI....lol

sprintex no longer supply that cai, but i have done it anyway waste of time

If anyone is still not convinced even after countless people have reported gains by trying this cheap and reversable mod, here are some threads with Dyno proven results that show that the standard intake snorkel is not the best flowing option.

From this thread HERE (http://www.aussiemagna.com/forums/showthread.php?t=19962&highlight=CAI+dyno)


Oh, something else of interest. Rob and Nick did a dyno run with the intake from the airbox forward removed and the difference was a gain of 3-4kW.


From THIS (http://www.aussiemagna.com/forums/showthread.php?t=6939&page=3&highlight=CAI+dyno) thread:


I took it for a back to back drive with the original intake and does pull a bit better from about 2500 and up, jackpot! nothing major but can only get better.

And from THIS (http://www.aussiemagna.com/forums/showthread.php?t=22967&highlight=snorkel+dyno) thread:


CAI is definately worth doing. In combination with the other mods I had at the time the difference between my bodgy $15 PVC CAI setup and the factory intake snorkel was on the order of 6kW ATW tested back to back twice on the same dyno.

There 4-6kW gains by removing the standard snorkel and/or a proper large diameter, (read; less restriction intake pipe, or affectionatlly called drain pipe by the doubters).

I agree waste of time, that pipe attached to the standard snorkel looked like an afterthought.

Cthulhu also had gnarly cams and aftermarket ecu.

The other day I had my left headlight out and so I pulled off the snorkel too and went for a drive. I needed spine surgery afterwards because of the neck snapping difference. It definitely unleashed like a thousand kilowatts. Those mitsubishi engineers were idiots designing such a silly plastic moulded snorkel, they could have saved thousands by cable tying ribbed drainage pipe from bunnings to the engine instead.

(There was no difference. Leave your air intake alone)

If you read carfully, the difference of 6kW was between standard and modified intake.
I have posted a FEW links showing there is a difference (you point out one), not a miracle difference you obviously expected, but then again no one ever said it was (we're only reducing restriction, not enhancing combustion). It's cheap and easy, and if you find no difference like you did, you can always easily revert back to the standard setup. It doesn't hurt to try.

You simply could have stated you found no difference, but instead you got all worked up, replied condescendingly and come across as ignorant. Now I don't know you so I particularly don't care. But this is a technical forum about Magnas. If you disagree with something post you results and others will do the same. This give new members a chance to make a decision for themselves by looking at ALL the results.

The way in which you reply brings the maturity level of this forum down unfortunatlly.

Well said Phonic.

Now I'm definantely a hater of useless "miracle" mods, but I am pretty sold on the case of the "drainpipe" CAI.

Can't say I feel any diference (I don't think 5kw atw is enough of a difference to feel), but what is noticeable is the way the car seems to breathe better at high revs, power doesn't seem to drop off as savagely after peaking. Not a huge difference, but noticeable.

Out of skepticism I have switched between my drainpipe and the stock snorkel a few times. Every time the drainpipe stayed on in the end.

The seal that ran across the front of the cars(the one that sealed on the grill)was TE/TF and maybe TH.It was definately deleted by TJ.
This is my two cents worth in this disscussion about the intake.I use a NZ domestic market intake on my 3.0 litre wagon.I found it gave a sweet spot in the torque above 2800 rpm and an improvement in fuel economy.The differences in both weren't dramatic but were noticable.
