Another which intake...

[Ronisonce]

When I bought my truck it had a K&N Cold air intake.. I want to get something that filters better, should I go with another intake or go with a stock unit? It seems that price for price I can get either a used stock air-box or buy another intake. Thoughts on best filtration ?

The stock filter is the very same style of filter used by Hospitals because it can filter out airborne bacteria. The stock filter filters to 99.97% efficiency down to 0.03 microns having at least a 3-1 aspect ratio (for intents and purposes, 0.03 micron rating).
That style filter is also used by Asbestos Removers, Lead Paint Removers and even in Nuclear Power plants. It stops Asbestos fibers, lead dust and radioactive particles.
This style of filter is known as a HEPA (High Efficiency Particulate Air) filter.
There is no better filter.

That is some pretty good information NYC.

Agreed. My filter box is broken, so I was thinking of just getting a different intake instead of buying a new box. Now I guess I won't.

now sure how much a new OEM box will cost but if it costs over 200 your better off getting an aftermarket intake for just a lil bit more...

It just doesn't shut all the way in the back. I've not priced them though.

I think both Afe and S&B have filters that will fit on your K&N piping.....that should give you the better filtration you are looking for with less cost than a whole intake.

Just remember if your going to run an aftermarket filter you might need to run shorter service intervals......thats why I always have a clean spare filter with me in the truck.

I think if I was driving through any of that the last thing I would be worried about is how my motor breathes.......

I would look into getting a new filter that fits the intake you already have. Like alwil mentioned AFE and S&B make filters that are direct replacements for K&N intake systems. An AFE pro-guard 7 or S&B filter mated with your existing K&N piping would be the best bang for buck! That is exactly what I have done with my truck, I was given an Airaid intake but it didn't have the filter, I found an S&B filter with the right dimensions and put it in the Airaid box. Here is a link to the S&B filter I'm talking about.

F-Series 6.0L (03-07)

The point was that the air coming through that filter and entering your engine is quite a bit cleaner than the air you are breathing right now.
Clean intake air = cleaner internal engine parts, less wear, longer lasting engine.
