Okey doke, Well I have the reminance of TH Smokers CAI kit however I dont like the idea of the MAF sensor so close to the ground.
Would the MAF still function correctly if i left it in its OEM position and ran piping down to the front bar with the pod?
Or would I have trouble with idling like some people do with round pods?

I was thinking of using the POD adaptor for the MAF and instead of sticking the pod on it, just clamping some rubber piping onto it and running it down the front.

<disclaimer - I have never had a CAI setup>

Personally I think leaving the MAF in the factory position, and running a pipe wherever is a MUCH better idea than moving the MAF. Moving it just seems difficult, more likely to cause problems, and is entirely unnecessary.

<Disclaimer- Got TH Smoker's CAI but haven't put it on yet-too lazy :D >

Here's my understanding.

With the stock/K&N panel setup, the filter is adjacent to the MAS, providing a STRAIGHT, non-swirling flow of air essential for the MAS to give a correct reading.

With TH Smoker style CAI, the pod bolts directly to the MAS, giving the same result.

With a pod at the bumper and the MAS in the stock position, there would be 4 feet of pipe in which the air would unpredictably swirl, giving a false reading by the time it got to the MAS.

It seems that a pipe feeding to a hole on the bottom of the stock snorkel setup would be the best compromise.

Or get a Turbo.... :bowrofl:

To overcome the swirling air problem, by runing piping to the ground, use a K&N oval pod filter. So you should be able to run piping from the MAF (leaving it in its original position), to the ground, put on the oval pod, and you wont get the swirling effect.

But mounting MAF that low to the ground, then having the pipe would the air not swirl after the MAF causing problems??

Obviously a pod at the bumper is a dumb idea for several reasons. The best option in my opinion is MAF in the original location, with pod directly in front of it (basically in the factory filter position) and then piping to wherever you need it.

On the topic of swirling, I have yet to see anything other than conjecture to suggest that this actually happens, or that it is detrimental to the performance of the engine.

Had a pod with an RPW kit and it killed the MAF sensor from water ingress :rant: . I wouldnt do it again, now I can drive the car when it rains, yay! It did make a fantastic noise though.

Well I installed it with a Simota pod at the bumper with that $30 pipe from autobahn up to the MAS Pod adaptor, onto the MAS sensor.

Seems to be running fine atm.

no, infact i believe it is actually a good thing to have swirling air entering.. only problem with swirling air is while is running through the sensor... if it swirls after that the its no problem.. perhaps someone else could it explain it better

If you keep the bends big and reduce the sharp changes of direction there will be less air swirling prior to the MAF. The honeycomb mesh is a big help with straightening the airflow for vortice reading anyway. Once ram air effect is engaged the air will tumble less as it's busy getting shoved and/or sucked into the engine depending on load.

since when do you get cold air off a hot road in summer better to run cai up high as possible and the other reason is to keep water out and havent magna air flow meters have a hunny comb mesh in front of the sensor to stop the air swerling?

Love your sheer ability to spell :bowrofl:

I know that my road is far hotter than any engine bay :nuts:

Yes, keep it high up to keep the water out, the HONEY (note the spelling) comb will steady the airflow.

Personally I can see no reason an adaptor can not be made and then run the cold air up to the MAS.

Better still, keep the filter where it is, run the CAI into a cold air box, bring the inlet through the front bar where the driving lights would go.

Would be a "largish" job but far more worth while.

Agreed, except if you've already got foglights, you've got nowhere to run the pipe to other than butchering the lower section of the grille.

also, remember that the closer the MAF to the filter, the more accurate the reading.
