    Folks help me out here please. I agree that the sound of the engine under acceleration is greatly improved with the TRD or any other aftermarket (AM) intake. I have found that there is also an improvement, albeit not as great, with just adding a high flow filter like AEM or K&N. Since the TRD fits the same location on the inner fender wall, why not just drill lots of holes in the stock box? From a purely physical perspective, you can only push so much air down a certain diameter pipe without a booster pump and since these systems are passive the only way to do is by a less restricted filter media to increase the velocity of air into the engine. Has anyone ever seen specs on much much more cubic feet of air per minute (under full throttle) the TRD or any other AM system can deliver over the stock? What I dont see at AEM or K&N, is the particle size filtration specs like some manufactures do for cabin filters, such as 5 micron. Isn't that what we're after in the air filter? Has anyone ever seen these particle filtration sizes? Has anyone ever read what particle size the filter media should remove to protect the engine? Thanks.

    Blacked out badges, window deflectors, smoked 3rd brake light. I have a Borla muffler on order as well as some color matched engine cover stickers. I'll be painting the stock wheels soon as well. Falken tires in the fall as well.

    Thanks much Blue 4ever, most excellent and just what I was looking for. I think I'll stick with the dry paper filters. I might pick up a used stock filter box and experiment with drilled holes. Happy 4 wheeling.

    You would be sucking hot air from the engine compartment, yes, no?

    It will if he drills a bunch of holes in it.

    I have both the CAI and exhaust. Yes there is a drone when under load or when I jump on the gas. I kind of like it because it feeds the old man race car that’s left in me.

    I ordered an AEM air filter directly from AEM ($40 free shipping) and my paypal account was charged to K&N Engineering, so essentially the AEM Air Filter is a DRY version of the OILED K&N Air Filter, it even looks the same, except its not pink or oiled. I went with the dry version because on my last 4Runner, I had an MAF Wire break due to oil buildup, and the Toyota dealership recommended not using an oiled filter.

    Wouldn't cutting off the resonators on the stock intake and plugging/covering the holes get you the sound you want from a CAI and actually be a CAI(oem) for minimal $ ? Just a simple mod I would think. Or will this throw codes?
