What is bogging?
Bogging is when you step on the gas and the car doesn't move for 1-3 seconds. It's caused by the incorrect design of every other intake out there except TPR, making the engine run too lean (sometimes leading to CELs that can only be eliminated by reinstalling the stock airbox). It can also cause dips in power in midrange, as well.

Injen and AEM don't always cause bogging or a CEL. I have an AEM cai and I've had no problems with it ( bogging or CEL) and i've had it on my car for about 2 years. The TPR guys tend to bash every other intake out. I think it just depends how good you install your intake, like make sure you have your hoses connected right and everything plugged up.
True that it doesn't happen to everyone, but if it does happen to you, you'll be rather annoyed with it and try everything you can to get rid of it. A good 50% or more of TPR's CAI customers have had bogging and CEL problems with their AEM, Injen, RMM, etc. CAIs and SRIs. The others don't even want to have a chance at bogging with the above intakes, so they bypass the potential problem completely.
Installing the CAI properly doesn't have anything to do with bogging. Incorrect installation leads to CELs, due to improper installation of the vacuum or EVAP systems. Incorrect installation of the VSV hose on the side of the intake piping won't throw a CEL or cause any performance problems, but will eventually wreck the VSV valve with all the dust and dirt ingested, causing emissions problems (valve is used to suck in air for the charcoal canister and fuel tank). The only other thing that can cause bogging is a dirty MAFS, but cleaning it is usually the first step people take to stop the problem.
