    hello, I'm shopping for an intake and I am seriously considering a k&n drop in filter with an upgraded resonator tube, or an AEM intake. I have some concerns though.

    How does the stock MAF sensor work with a open filter intake like the AEM? I have read some material that claims the benefits an open air intake like the AEM are negated by the MAF sensor. So basically, to get the most out of an open air intake (AEM) you need to upgrade the MAF sensor, add an additional o2 sensor and reprogram the computer. Is the k&n a better choice because of this?

    I have also seen that hydro-lock can be the cause of an open intake. I understand bypass valve can also prevent hydro-lock. Is the stock air box is designed to prevent hydro-lock?

    Finally I'm wondering who makes a good aftermarket resonator tube.

    I really appreciate any feedback.

    I've never heard of the issues you mentioned. The stock MAF flows plenty of air, up to I believe 600hp. It does help to go with a good programmer like the Diablo Preditor. This will complement your intake and exhaust. I've had K&N drop-ins and other CAI's and have never had any issues. I'm running the Banks CAI now, you can see it on my album. I do think the most bang for the dollar is Airaids Jr. Kit, it has a drop-in filter and intake tube without all the baffles in it.

    yeah, do not change to an aftermarket MAF sensor... there is no need... the stock is good for 550-600+ hp anyway... and will be fine.. and leave the screen in it too!

    the aftermarket ones fool the pcm into thinking the engine is running leaner than it really is.. bad bad bad....

    get the diablo Predator, model U7198, like silveradotb mentioned above...

    thanks for the advice,

    so just to clear things up, is it worth using the AEM brute force intake with the stock MAF sensor or should i stick with the stock air box with k&n filter and upgraded resonator tube?
