    What are you looking for specifically? The stock unit is a cold air intake. Aftermarkets all pull air from a hot engine bay and don't increase power. Plus the stock filter is very very good.

    Only thing you may gain is more noise.

    Welcome to the forum. Might not be the answer you were looking for but Shaggn is right. Aftermarket filter setups especially for a forced induction (turbo charged) engine typically only add heat from the engine bay a negative for power creation and reduce filtration another negative. Yes a guase filter may reduce a little of the paper filtration restriction but that was already easily overcome by the turbo. Many add some induction noise which some see as a positive other see it as a negative. A tune would be the only practical way to add measurable performance. After that a little performance could be freed up by opening up the exhaust track but not much as it’s still not a major restriction.

    The AFE Magnum Force intake can pull cool air from the stock wheel well location or hot air from engine bay depending on if you keep its lid on or off. (see pics)

    AFE claims more HP and Flow per Dyno. That's up to you if you believe them.

    Per my own UOA's and their Silicon levels the AFE dry filter works just as well as the stock filter. (note: the blue filter in the pic is theor oiled filter. I have their grey dry version)

    Yes, it will increase turbo noise. Post AEM I now get turbo bark from back pressure when I let off the throttle quickly after accelerating quickly. I don't have a lead foot so I've only experienced that while off roading.

    The increase in HP and TQ is in a fairly narrow band of RPM. I'm no engineer nor a mechanic but that's not enough for me to make such a change. Some are on a MPG quest, some on a HP/TQ quest, and others are on a bling quest. But, to each his own.

    If I recall correctly, GDE did some air flow tests and concluded that you could not improve the OEM air filter system. There may products that increase air flow but the limitation is the turbo, it can't use more air flow.

    look at the run conditions listed at the bottom of the HP/Torque chart. It was 14 degrees cooler when they ran the test with their intake, humidity was considerably different too. I don't know if that alone would cause that much difference in the outcome, but it shows this is not an apples to apples comparison

    Add to that most flow increasing mods gain more on the top end instead of the bottom end.

    I wouldn't buy it.

    I know you said Air Filter System but here's AFE's air filter flow test results. (see attached)
