It wont collapse unless a 3400lb car lands on it lol.
I get them from a local dirt track store, they use them on SBC valve cover breather tubes. I have never found a K&N number for them, they have like 100 of them in a bin and I bought a few of them so I never looked into a K&N number.. Some are half covered like the one in the pic and some not.

It cant hurt to have the extra small filter on there, path least resistance will draw air from anywhere it can. I also spent some time and radiused and polished the plastic where the big and small filters attach. Not sure that helped any but it only takes a few minutes.
This is what I have used to run 8.90 @ 152 with a F1A and 9.11 @ 149 with a D1SC. It was starting to run out at higher RPM with the F1A but I dont think it would hurt a D1SC much. I have seen the same the same big dyno increases taking the inlet off but it never translated to anything at the track. I'm sure it would kill a F1C/F1R, which it doesnt fit anyhow.

Looks like it might be this series from K & N. I didn't know they come with a protective shield as I ordered one from Autozone rather than looking at K & N catalog. So will order one with a shield this time.

1" I.D. 62-1511
1 1/4" I.D. 62-1512
1 3/8" I.D. 62-1513
1 1/2" I.D. 62-1514
1 3/4" I.D. 62-1515
The bigger filter recommended by BOB at EPP didn't fit due to my custom piping but an E-1009 will fit. See pics. It pulls about 100 cfm less than what Bob recommends.

I dunno, but hard to argue with taking it off and it runs no faster. Since I was using closed loop wideband controlled fueling it wasnt the tune. Since my car within a tenth for many passes in a row it certainly wasnt a fluke, I tried it many times at the track. I never picked up 115rwhp on the dyno, 65-70 at the most with it off.
This isnt exactly a new topic, all I can say is if my 8.90 car would would have run 8.80 without the inlet hat dont you think I would have left it off and ran 8.80? I mean loosening up a hose clamp and taking the filter/hat off is so much work at the track

I'm not sure how much the little air damn helps. But the combination of porting it, extra small air filer, air dam and giant air filter must all add up.

Hey Bob, have you done back to back dyno testing with that truck hat vs the stock fbody hat yet? I'd love to see the results of that test (with both hats using the same filter so we know how much gains came from the hat itself- I already have your bigger filter). I'd definitely buy one if it made a difference. ![Grin](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_grin.gif)

Anyone tried one of these out? I am seriously considering trying it out but don't see how it will fit with my bypass in the way

If I were to remove the original bumper bracket which I intend to do and make a new bracket to hold the FMIC - the bigger filter will work.
I run AC and have the larger BeCool radiator so there is less than 1/4 inch between the stock ATI plastic hat and the ATI fan shroud.

I wonder how plausable it would be to fabricate up a metal inlet box similar to the current ATI one, except have inlets on both sides. I'm not really sure the size of the filter you could put on the passenger side though.

Picked up 3 #'s of boost with the little filter and I swaped out the stock procharger cone for a bigger one. http://mycarpics.shutterfly.com/276

Here's one with dual inlets that I made for myself a few years ago. No back to back dyno #'s but it definitely "picked up".
