20+ hp you should be able to feel it.
Also, as the webpage doesn't state it, at what level of micron does the filter filter down to? Oiled and Non-Oiled?

One thing I can report though, Charles at AJUSA is really good to deal with from what I've experienced so far, answered a bunch of questions and had quick email feedback, Thanks !!

So is part 401-299 the one with the tube also and not just the basket and filter? Is the 401-299-1 just the basket and filter?

I am comparing pricing and am trying to ensure I get the best bang for the money but not sure if the tube is necessary but seems to be a wanted item if you are going to get the full benefit, right?!?

Also, to answer my earlier question - oiled filter is 820 CFM, while the dry is 1400 CFM.

I can't get an answer on if the dry traps the same as the oil but from the CFM off the website it seems to appear that it doesn't.

What about the prefilter? I can't seem to find details about it's affect on the airaid filter whether it decreases CFM % and what additional filtration it does.

Not sure why this information is not redially available or is it just not everyone cares but if I am going to change something on my truck, I want the details.
