POD Filter And Cold Air Intakes A Myth???

[06 Sportivo Bloke]

I was watching some youtube vids and apparenty mighty car mods have mythbusted the 2.

I watched them and wanted some input from some of you guys that may have fitted them.

Any significant before and after gains?

I used to, really not worthwhile gains, if any, for the cost.

Apart from some nice induction noise nothing really noticeable. I just stick to the standard airbox now myself

You can't put a blanket "busted" down on something which varies from car-to-car, dyno-to-dyno and day-to-day. If you have a car with a really bad intake, switching to a pod filter and CAI can really make some improvements. If you already have a good air feed and nice un-restrictive factory intake then switching will probably have next-to-no effect.

And CAIs can't really be judged on a rolling road/chassis dyno, as the air flow and engine-bay temperatures are not indicative of real world situations (note most dynos will open the bonnet for instance, which reduces engine-bay temps and reduces the difference between a normal intake and a cold one. Also, cars on a dyno can get up to 180km/h+ (the Soarer for instance hits ~190 in 4th), so unless the fan can generate 180km/h winds, you're not going to accurately replicate the airflow over the car and thus any high/low pressure areas and ram-effects (also note that the fan will be drawing dyno-cell air which usually be warmer than ambient outside air.

Sure, on a lot of cars, especially "low"-powered N/A cars like a lot of ours would be classed as, a pod filter and CAI may gain a couple of kws here and there (maybe a few more on the butt dyno), but there is no denying that a properly designed, built and located cold air intake (especially if it helps to remove factory restrictions) can significantly improve the performance of a more powerful car, especially turbos as they luuuuurve cold air.
