I bought a CHEAP intake kit off eBay that came with the tubing, couplers, mass flow sensor adaptor and new hoses all for about $35. I then bought a K&N filter that matched my vehicle that i had looked up on their website for about $62. I then went and bought a sheet of 1/4 high heat plastic for about $9 and fabricated a half box kind of like the K&N set up. All in all i spent a little over $100 and have a set up thats pretty much just like the kit that K&N sells for $260 for my 5.4L. And it is a pretty noticable difference. Just goes to show that you can save alot of money with making something pretty similar. Hope this helps with anyone that would rather do it themselves than have someone do it for them. Especially someone that likes to save every last doller
