The point is the engine doesn't need a high flow filter if it doesn't flow that much air anyway. You can't get better performance if the filter can outflow the engine.

Point taken.

My point is dirt in the filter will restrict airflow. If not, why do you ever have to change/clean it? The less restrictive filter will remain the less restrictive with the same amount of dirt packed into it. If you are saying there is no point at which a clogged filter restricts airflow then you are dreadfully wrong. By your logic one should never have to change the factory filter.

Anyway, find a paper element filter with factory specs that is cleanable/reusable that is cheaper than both and I'm in there like swimwear.

Otherwise: 1x $54 K&N > 1x $57 AER > Many x $24 Fram filters over the lifetime of the truck.

After reading the link that I provided on post 77 I have decided to go 60k miles interval before changing the filter for me. They found no change in MPG but reduction (7%) power with filters that are 2-3 times more clogged than a filter with 30k of use. A dirty filter actually filters more, which is a good thing. No argument a very dirty filter will reduce peak power, but not with your typical 30K interval.

With my 2.7L I don't care if I lose a few HP at 5500rpm, I don't see that engine speed anyway. I picked up 3 oem filters at the dealer for $14.99 each, that's 240k for $45 including the original.

I do a lot of beach driving here in corpus and it's super fine sand that gets everywhere. What do you guys recommend for me? I like the idea of the dry filters as I don't want to deal with the oil gunking up anything. However would the dry filters offer enough protection? Is my best bet just to stay stock paper filter while I'm living here?

How much does a CAI help with mileage, I have been on the fence about one for a while, wondering if it is worth it.

I would recommend NOT removing the secondary filter first of all then just cleaning/replacing more often whether you use oiled, dry or paper.

If you still have the secondary charcoal filter in the stock air intake on a 2nd gen, an oiled K&N drop-in will never mess with your MAF. The secondary charcoal filter is eventually, way way down the road, going to get dirty too. Then what, buy a whole new lid to get a clean one? Wash it off with lid removed from truck? Remove it and go more? It's just a matter of reusing or filling landfills with old filters. None are any better or worse. Just choose one because clean or dirty is the only real difference.

Does the AFE pro dry add any performance compared to the stock filter?

I really don't think oiling the filter is a pain in the ass, and plus I've never had a MAF problem.

I have the TRD intake kit, and I have no complaints. I don't think I've ever heard of anyone over-oiling the filter.

The oil is spray on, and it's dyed red. Spray it on, just enough to tint the media red, then let it sit on some newspaper for 20 mins or so. If it's running out of the filter onto the paper, you put on too much. Clean it and start over.

Seems easy enough to me. Isn't the AF-e kit more expensive?

That's a nice looking setup right there.

Looks great! That's a serious air setup! How does it sound??

Going with the full CAI short ram would be a diminishing return over just dropping in a Pro Dry methinks...

I didn't care for the open filter in the bay like the K&N setup is. Soaked up heat even with the divider wall and also soaked up moisture enough to bog the truck on frwy in hard rain. The sound is noticeable with header and intake but is different and not brappy with filter enclosed in the box like it was when open. Other than the enclosed kind of setup, just the pro dry s drop-in in the oem box is next best IMO.

Great. Thanks for the feedback. I can def see where you're coming from not wanting the filter out in the open like that. Wish they made a fender mount like I had on my old Foxbody mustang. What's your total bill for a setup like this if you don't mind me asking? Seems like a ram air and closed off box like you have is probably the best setup you can run. I'd like something like that also with some LCE headers. Do you see any real loss of performance or need for a retune? Running lean at all?
