Re: APEXi Intake Exy
I guess this would be a better option than the standard filter but not as good as the cold air intake (CAI)
Any feedback about these on the net you can share with us?
By the looks of it, it'll still be sucking hot air from the engine bay.

Re: APEXi Intake Exy
It is certainly a better alternative than the CAI from an off-road risk perspective, as it doesn't see as low as the CAI does 
Let me do a bit of research about this one using the magic search engine.

Re: APEXi Intake Exy
I think I have probably replied something similar to the following in the other thread but it doesn't hurt to include it here...
Hot air from the engine bay will have a negative impact on the engine efficiency. I had a similar pod style filter in my N15 pulsar and I ended up making up a heatshield for it (so really I would've been better-off putting in a standard-sized filter like Jalal's K&N panel filter (which incidentally is identical to the X-Trail's), after going to all that trouble to separate the filter from the hot engine bay air!).
The advantage a pod filter has is that it's much easier to put in a much bigger "cold air intake" duct from the front grille (or where-ever else at the front of the car you want to put it) to "force" cold air into the filter. I guess you could do the same while modifying the standard air box to accept larger diameter piping...
Being a more off-road vehicle than my lowered pulsar, and hence much more likely to be doing creek crossings (or even exploring deep puddles/pot-holes on Sydney's "excellent" roads), I'd steer away from using a pod filter in the X-Trail - and more importantly forcing cold air, which would turn out to be cold water in the abovementioned situations.
I'd say stick with the standard setup, and change the standard filter to a different brand if you're worried about lack of air flow through Nissan's filter. I'd also consider modifying the existing ducting - but the top of the engine bay where the opening currently exists probably doesn't leave much room for improvement as far as a larger opening is concerned. The only option would be to have a wide & flat opening at the mouth of the CAI. Also gaffa-tape up your factory plastic ducting (in front of the filter box) as water can also get in there, too.
And for those still considering "upgrading" to a pod style filter, I noticed the other day that SupaCheap has pod filters for ridiculously low prices (I can't remember if they were $25 or $50 each) - and they looked identical to the one I had in my pulsar (which cost me over $100!), but I couldn't vouch for the quality or air-flow characteristics of them. They also had some flexible rubber/plastic piping (for the CAI) in approx 80-1000mm length and around 3inch diameter, and also the mounting brackets & adaptor plates for the pod filter, too. So even if you're someone that's keen to experiment with the whole idea, it would be a pretty cheap experiment to play around with...

Re: APEXi Intake Exy
Thanks for the info. Rich
I'm a bit sceptical about the pod set-up as well and I have been searching Google last night and today with no luck with any similar set-ups to the one shown by Robin above.
I think he's the only xtrailer to have done this.
There are many set-ups with the CAI that is mounted in the corner of left fender, but as I said below, it is out of the question for someone doing off-road and creek crossings.
Had I installed the CAI before attempting my deepest water crossing, I would have been in serious trouble.
The optimal solution is the SNORKEL
