These trucks love a little n2o.

So you're saying just the efans alone will give that kind of a bump? Is that with most engines? I have the 5.3 and I'm looking at various things to help out.

I don't have the K&N although I plan on one when I have a little extra pocket change. I have a 2000 'Ho with the 5.3. In looking at where the K&N mounts, and where the heat sheild fits I got looking at the air flow. There is a narrow flap that runs vertical along the side of the radiator. There is also a rigid panel behind the headlight assembly. It looks to me like if you removed both of these the air would have a straight shot through the grill at the filter rather than still needing to come in and around things. If you did this I would think you would need the waterproof pre-filter to cover the K&N filter since the filter element is so close to the front if you opened it up like this rain would come straight in to the filter as well.

I have a K&N intake on one of my Z-71 trucks. I trimmed my intake tube to fit and left my fan alone. It worked fine for me, I just never thought of the fan blade trim idea. I also didnt notice much difference from the TBS, but it sounded cool. I dont drive that truck much any more, and now I think I'll drive it tomorrow so I remember what it sounded like. LOL

I ended up going the the AEM Brute Force. Easy install, no clearance issues, nice clean fit.

You have to get the PCM retuned in order for the electric fans to work with the Nelson Performance fans to work. Don't expect any noticeable gains with them. You're probably going to need to upgrade your alternator is you use them, too.
