scored this puppy off Ebay - EMTECH actually - and tonite got stuck into things with the Dremel to get it fitted - its almost a very neat fit. Don't know if it'll make much of a difference but who can leave well enough alone anyway.... lol lol

Ahh you bought it!!!! there was a thread about it just recently!

Let us know how it performs :)

Yeah well someone off here was going to buy it for sure so I jumped on it - I don't really know how much of a difference it should make but I wanted it fitted for the run on Sunday to the Blue Mts so we can see how it goes.

Well at least it looks neat... as long as there is enough cool air drawn in behind the headlight assy to keep the warm engine air out as much as possible... certainly better than my set up right now... nice one

Well after a few weeks running with this puppy I can say it does add a little something to the ooomph factor though I don't know about the extra 7KW claimed. Sounds nice too (though I have the Mitsu VRX exhaust, not the standard setup).

And to fit the thing is more like 2 hours with the Dremel not 10 minutes.... But anyway I'm happy I bought it and the point is here's another one for sale if anyone is interested:

The intake at the end is (at least from the pictures) looks quite small in comparison to the entry to the airbox...

Would have thought that it would have caused a bit of restriction.

hmmm would there really be any advantage from the stock cold air intake?
Only reason I ask is I dont think the stock setup is too bad. It comes pretty much straight from the front and only gets cold air. The one you have has a big bend and doesnt have its intake directly from the outside world. It has to come from below the headlight...

If anything, the CAI he has placed on his car is more of a restriction of air as its way to small and no air is being forced into that little hole/pocket where his battery is. (the hole is sideways which is another factor for not allowing direct air into the box..)

IF anything, he should have used a few thermal sensing probes to find out exactly how cold the air is in that spot and if anything is even going into there.

Stick with the original and just hollow it out some more, even add a 2nd CAI below the current hole and run a duct up from the bottom of the car.

Well, the fellas that tuned my car said that they did a run, (out of interest - which I thought was pretty cool), and said that it gained 3-4kW.

/whoops. I think I misread your post. Anyway, the factory one is restrictive. Not sure about this one.

Seems a like a side-ways step to me. No substitute for a big gaping tract of PVC to the front bumper or driving light. Or a shaker kit :think:

Actually - it doesn't. It should, but then the seal at the headlight end of the bonnet would have to bend up and around the shape of the scoop - as it does on the Evolution VIII. In the Magna some 'genius' ran the the seal straight across the mouth of the scoop which seals it off from cold air and means its sucking air from directly underneath the flat surface of the bonnet - the hottest possible in other words.

The stock setup while it looks ok is actually pretty poor, the moulding itself is ok, but the way it gets it's air is terrible. If you look at where the moulding meets the bonnet(or avoids it rather) you'll see in front of that is the rubber sealing strip, this means that the air has to route from either side above the headlight and travel along the radiator support and then into the pipe, not only is this restrictive but by the time it reaches the stock pipe it is already somewhat warmed up, to make the stock pipe efficient a cutout needs to be made in either the plastic shield above the grill or in the rubber sealing strip, which I wouldn't recommend as it will probably lead to wind whistle.

P.S : Both Cthulu and I got a dynoed 6kw increase by running pipework to the bottom of the front bumper, this is an indication of how bad the standard piping is.


Bah I type slow, got beaten to the punchline :P

Okies, firstly, I agree with Bain about CAI set-ups. All you POTENTIALLY need is a secondary pipe running under the original. That's the way Sprintex did mine and unless you look under the original set-up, you would never know it's there. Not ricey enough for some but I personally prefer the sleeper look.

Why did I say 'potentially'? Because you will generally only make gains from an ADDITIONAL CAI system (your car already has a perfectly good one from the Factory), if your engine has been modded to the degree that it would ACTUALLY benefit from the addition of more (cold) air being introduced into the system.

In the case of my Supercharged Sprintex VR-X, there is certainly a greater need (over a mildly-modded car), to get more, and colder air into the system. But, and a really BIG but, only up to a certain point. After that certain point, any additional (in this case), air-flow modding, becomes redundant because the 'system', quite frankly, doesn't need any more air for peak efficiency, as determined by tests conducted by 'expert technicians'.

The same principals apply to exhaust systems. Erm, only in reverse, mostly.

And btw (nudge nudge, wink wink), a skilled professional (one who is more interested in your performance (legal) mod desires than ripping you off), can do wonders with filters, the guts of Factory airboxes, exhaust systems, etc...allowing gains but still keeping everything nice and legal. (Say no more). :cool:

Oh, and lastly, I agree with some of the others that your CAI's intake is not positioned for optimum performance. Quite honestly, to me, it looks like a CAI trying to impersonate a Turbo or Supercharger unit. If that was the intended look, cool. :)

Redav also found that the guys who dynoed his car found an axtra 4-6kW with the standard intake taken off :P

VR-X IIIt's not about MORE air, it's all about COLDER air. Our car's certainly do benefit from colder air. Take your car for a run to Lithgow or Bathurst (as NSW did recently), and even after driving all morning, making our engines (and engine bays) nice and hot, there was a bit more oomph from the colder air.

It's about the mass of air. Colder air = more air anyway as it's denser.

I agree that probably the best CAI is to run a 90mm/100mm pvc pipe from the stock airbox (i used to have this but got defected)
But there is another way...Cut the front bonnet seal in front of the snorkel and remove the plastic crap/sheet that runs along in front of the snorkel and around the bonnet latch. (both blocking heaps of air). Works great, a test b4 and after showed a definate increase in induction noise (i still have all my resonators) so i should be getting higher pressure & colder air.
Also as I am now on my third magna (3rd gen) i have noticed that the snorkels seem to warp over time due to the heat in the engine bay especially where it attaches to the air box, collapsing in on itself restricting airflow. Easily fixed with a new one.

You got defected for it? How low was the pickup point?
