hello new to the site.01 5.9 auto off-road. wich cold air intake are you guys using and with what affect.already have the k&n drop in. thanks guys i wish i knew about this site when i had my 95

 

K&N FIPK GEN II

From what I hear, it's the best intake out there. It's the ONLY one for the V10s (in my case), and it sure seems worth it.

 

AFE magnum filters, Saw a few K&N Filters kits, wasn't impressed.... Saw the AFE filters.... bought one, LOVE IT!

 

You could always make something like this. It cost me about $50 total in parts for the tubing, air hat and filter. I cut a hole in the shroud next to the radiator so that it can draw cold air in from outside the engine compartment. Works very well and I saved enough over the K&N to get a throttle body.

I have an Airaid that I modified on mine, I insulated pipe and added a 90* elbow to put it directly in the path of cold air, pretty sweet.

 

K&N FIPKII i payed for what i got... all im gonna say!

 

My only problem with the K&N was the having to relocate things under my hood, I just bought the basic Airaid and modified the flap next to the radiator to allow cold air to flow directly on the filter after I added an extra pipe, basically as good as any you can buy or make, just have to get cold air to it.

 

Cheapest piping you can find and K&N filter. If you want a intake from a brand name K&N or Airraid probably. All the major brands should be fine.

 

Follow this link and read what it has to say about the K&N filters. I was going to buy a K&N until I read this. After looking at the charts, I decided that K&N was not the way to go.
