    Looking to add the K & N Air filter system to my '07 Silverado LTZ with the 6.0 liter engine. It was also recomended to me to add a throttle body spacer. As I don't know much about these, are there any brands better than the rest? or are they pretty much the same?

    I've never bothered trying one. Can't see how one chunk of aluminum would be better than another. There are lots of posts about spacers. Try a keyword search, while waiting for the gang to chime in with their recommendations.

    I have the airraid one but I dont think it does much on the newer trucks. It might do something on TBI or carbs. they are supposed to cause turbulance in the air to help atomize the fuel for better burning. But in the direct injected systems the air and fuel arent being mixed until its in the chamber and i dont think there is much of turbulance left at that point.

    Maybe I'll just go with the K&N air intake and see what I can gain from that. Thanks for the replys.

    I have the S&B intake, and it is far better then the k&N. I have owned both. The S&B will give you better gas milage, and supposedly better horsepower, but i havnt noticed much yet. If your going to get a spacer too (which i would recommend) make sure you get both from the same company. I know AirRaid, and AEM both make intakes, and spacers. I cant tell you which ones better, but if you mix and match companies they might not fit properly.

    I have an Airraid spacer with an Airraid intake, and I gained no improvements, just sound. The spacer adds a whistle under load is about all. IMO, it's not even worth spending the money on the spacer.

    I have a Speed & Performance Electronics TBS and I love it!!! I had a PowerAid but did not like it!! like Jimmeh said, the PowerAid does whistle bad!! but I have the K&N 57 series CAI and I love it!! those two are my two biggest mpg helpers!!

    If a machined piece of aluminum could increase power or gain gas mileage, GM would be all over it as OEM.

    When I put the spacer in I noticed a small increase in throttle response. A very small increase of gas pedal would kick down a gearand giddy up. However the best thing you can do is add headers and high flow exhaust. That is an immediate boost you can feel with no doubt!
