03 2500hd cai problem
i have a 2003 silverado 2500 with 6.0l engine. i bought the truck a couple of months ago and have recently decided to install a cold air intake. so i bought a k&n 57 series cai kit and tried to install. long story short it didnt clear the fan. after doing a little problem solving i discovered that my truck has a throttle body spacer installed. so my question is to all you guys with throttle body spacers what do you do to install an intake? is there a brand that will be able to clear the fan or what. or is the only way to remove the mechanical fan and install an electric one?

Just take the t/body spacer off and throw away. There useless on all the LS type engines. They work fine on TBI type engines.

you can replace your clutch fan with electric fans which will give you a little more powere, alot more room, and keep your engine cooler. there are fan swap "how-too's" on this forum. just do a search2000 silverado with a 5.3l v8, shorty headers, upgraded plugs, 10 mil wires, magnaflow high flow cats, flowmaster 80 series muffler(2 in 2 out) w/ 18 inch stainless silverline tips. i have a k&n CIA. its a 4x4 z71 offroad package. Ls model.

Its not that Im a hater Ippield, but when you work in the aftermarket industry and have acces to dynos and flow benchs you learn what works and what doesnt. T/body spacers work well on some of the older trucks (TBI style intakes) but we saw no increase in the LS family engines.
