View Full Version : To CAI or not to CAI that is the question

okay,

I know this has been sort of covered before, but my question isnt about whether to change the standard intake or not. But what would the gains be to CAI as against just fitting a K&N Pod in the enginebay.

Pods in the enginebay look very nce. Will see a monumental gain going the CAI route ?

Please anyone who has had a pod and then moved it to the bumper, I would love to hear your thoughts.

Thanks everyone.

a pod in the engine bay really defeats the purpose of a pod IMO. cos you are sucking in hot engine bay air any ways, so you may as well stick to the panel or K&N panel. if you want a pod, best to go for some sort of CAI whether it be relocating the pod, or sealing the aribox somehow and feeding some decent cold air into it. there is also the legal issue of having an oiled unsealed pod in the engine bay too...

if u can get ur pod down to front bumper then is more like real CAI but the gains from my understanding arnt huge for the effort really, u get a nicer induction noise to

..GONE..

mr altera has the same sort of CAI as TH Smoker has in his car.. and It has some seriously nice ass induction noise! Either then that.. I havent driven his car with the POD so I can't tell you what the difference is.. but from a passenger point of view.. All I can say is.. there's more exhaust burble now!

Also, His POD is relocated to the front bar.. All he needs is a drycharger though.. so that he doesnt get any water in there!

Theres everything you need to know right there!! Spot on.

I think most people who have have them fitted don't really notice a big improvement over the standard units (although if anyone disagrees feel free to say so).

I measured the cross sectional area at several points on the standard units and it's much larger than many points along the whole intake and exhaust system such as the throttle body and most of the exhaust. So it's unlikely fitting an after market CAI will improve breathing unless you've done other mods.

They are louder, look trick, may be illegal in some states, and may feed cooler air (maybe) than the standard unit. And I think they're about $500.

Thanks for the feedback everyone, I asked the question as in my TL I cant see how I can get the pod infront of the radiator. The radiator stretches right accross the front of the enginebay.

And having the pod behind the radiator is worse than at the back of the enginebay, as there will be HOT air feeding it. Maybe the radiator in the TLs are larger than the previous models.

if you are gonna put in a pod - put in a cold air box - or a cold air induction kit - cos otherwise it is pointless - though becareful with the CAI as it will put your pod low to the ground (great for cold air - but not so great for puddles!!)

The Idea of a CAI is solely to allow the Filter to be able to take in colder air rather than from the engine bay (unless there is a quality heatshield in the bay ie. AEM or ARC etc)..

It doesn't have to be sitting in an area there will be a flow of air coming in from somewhere along the front of car. Also, the bigger the area of the filter doesn't necessarily means it will be beneficial. It comes down to the quality and permeability of the material.

First mods any car modders would do will be the exhaust and the filter. with an after market filter, you will lose abit of power on the lower end but the top end improves and as for the HP increase.. every car is different, even if it is just amongst Magnas, they will deliver anywhere between 2-5HP, not dramatic but can be felt...

My Opinion...

Weeellllll CAI can increase power a little.

Lets look at the 60's US Muscle Cars, The GTHO Falcon and Late model Pontiacs.

They all have q forward facing cold air scoop. This forces incoming air straight into the guts of the intake system.

All have been proven in many a dyno to make power in these old clunkers. Imagine what it could do in a modern engine where fuel/air can be modifed on the fly !

So adding a CAI induction system that "scoops" air from outside will work. I supposed it's all down to the design of the system as to how effective it will be.

Speaking of which, TH Smoker whats going on? :confused:

I don't think the air would be much different to the ambient heat in the engine bay. You know, people say how there could be 10 degrees difference, (for argument sake), between the engine bay and behind the radiator but in reality, when temperature is measured from -273 celcius, it's bugger all.


This forces incoming air straight into the guts of the intake system.
Whilst this will ensure there's a constant feed of cooler air, it won't force more air into the engine.

A pod won't flow any better than a panel so if you can't come up with a decent induction setup then stick with the panel. The beauty of a pod is that it can sit on the end of some pipe to be positioned anywhere you can get it.

Lots to think about, thank you all.

Quick question, what is the K&N part number for the pod ? I looked on their site and it has a search for parts that suit car X.

When I put in a magna it only came back with either a oil filter or the panel.

Thx.

i'll get in contact with TH smoker and hopefully he'll get his ass into gear

whats the best way to set up a cold air in a tr, without moving the pod. coz theres heapsa puddles and mud where i live....could someone draw a pic????

Someone please let me know what pod filter setup works that mates up to the MAS sensor unit. A part number please :)

I contacted motor traders to get a panel filter for now ( I pay trade price ), but the TL uses a whole different airfilter to the previous models. As such no one has a hi-flow unit for my car. Only genuine ones exist at the moment.

Im hitting brickwall after brickwall here..

Help !!!!!!!!!

It does? Any chance you can take some pics of the air box setup?

Happy to, gimme a email addy and I will mail some to you..

No idea what the changes are, but both K&N and Ryco say they are different.
