    Default 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?

    I don't know what the layout of the engine is, but if your CAI has a hard pipe with it, you could just trim the pipe on the throttle body side of it.

    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.

    Why are you such a hater?

    Back on topic, Measure twice per cut. Like Land Shark said, little bit at a time. It'll probably take a while, but it'll be worth it to keep the Throttle body Spacer.

    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 search

    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.
