I have the universal K&N filter currently. It is pretty beat up because it does not fit well into it's location in the engine bay onto the side of the turbo.
Should I bother with cleaning, oiling and reusing this filter or is it too beat?
I've looked at some other filter options, for example K&N has a shorter cone filter, but I wonder if the reduction in air flow would hurt performance?
Then there is always the inlet mesh screen option....
I'm gonna have to dig it up but, I found a page on the interwebz that had great info on selecting the proper sized filter for your application. Helps you determine the surface area required by your setup. Good stuff.. Hint: almost all cone filters on the shelf will suit you wonderfully in the size you posted there.. monitor your WOT and cruise AFR after install for verification.. You will notice it there if it's not enough.
I figured the size probably wouldn't matter too much. But mostly wondering if the one I have, being crushed the way it is, is it a bad idea to continue using?
I have the 6" long one, going to measure and see if the 5" long one will fit better, if not will go with 4". Ideally I would route a pipe to get the filter into a more accessible area, but it is just not possible with how my bay is set up. The charge pipe goes right over the top of it, but was removed here so you can see the filter.

You can just clean the one you have. The cleaner/oil kit is about 20 bucks at most auto parts stores. With the price of that though, you could nab a new one. Up to you. For space, the one I have is perfect.
There is actually enough room now to add a bit of pipe to pull the filter off the compressor housing.
I think just to keep it easier to work on and to clean things up a bit I will order the smaller filter. Only issue I have is finding one for a 3" turbo inlet, since the RU-2510 is for 4". But maybe I can use the adapters that came with my universal one to make it work on the 3" inlet.
Already ordered the cleaner and oil for the filter It will come in handy regardless.

Are they the stepped O-ring type adapter things that the Spectre filters use? If so, those are awesome!
Probably the same. Different diameter rubbers that fit inside each other so you can go from 3" up to 5" I believe.
Why are you guys just stuffing filters pics the turbo inlets and not creating or using pipes to point downwards or in directions that allow for the filter to not be damaged in the first place? Childers may lose 7hp, but not worth losing the entire turbo for. You lose a ton of responsiveness not using a type of intake for the compressor inlet, and this has been stressed tune and time again. I'm just trying to understand outside of the exhaust manifold pursuing compressor inlets towards the driver fender. (BTW which many of my exhaust manifolds have done, so I don't want sympathize with many excuses )
You probably wouldn't lose 7hp if you had a larger filter, these filters you are all running seem pretty tiny. Like others have said, run an intake pipe then a larger filter. I've used various sized filters over the years on non-turbo cars and the larger filters definitely help with response and power. The below should be helpful on K&Ns site.

There is a restriction no matter the size of the filter. On the dyno, with the filter, my car made 317. Once removed, it jumped up to 324. That should clear up your assumption.

Hey, you found the calculator I was referring to! Lol
Because I have literally no space to run an intake pipe of any sort to my turbo inlet, nor anywhere to locate the filter other than directly on the side of the turbo.
The simplest way I have figured out how to do it would require me to buy a new intercooler with a single back-door setup, rotate the compressor housing so it blows directly into that, and redo all of my charge piping. Just so I can run a pipe to a filter behind the driver's side headlight. For now, no thanks. Maybe later on.

No. You can point it downwardlike a lot of us do, and use a K&N containment air filter wrap to keep water away from the filter since you have an open engine floor.

But it's not like NA world. Your torque/hp loss won't be significant enough to warrant risking the life of the compressor wheel from FOD.

AEM and Injen also both make a "hydromesh" or "hydroguard" type of pre-filter.
All together with a pre-filter and K&N filter together, whatever HP loss there is is extremely negligible and not worth risking the turbo in a trade off.

Unfortunately, either because I have an EF or because of my turbo placement, I cannot. My trac bar is directly below the turbo inlet about 4", by the time I even get a 90° elbow on there I'll be running into it. There simply is no space to route any sort of pipe, and barely enough room to fit a filter alone.
One idea I have toyed with is putting the filter under the drivers side headlight behind the bumper cover. But, I would have to blow a 4" hole through the chassis frame and this is structural to where my trac bar mounts so I'm not sure it's a great idea. It also would require some funky piping to get over here.
For now I am looking at the smaller K&N options and trying to find one with a 2.75" inlet size to match my turbo. I've had some issues with the universal one because the smallest coupler size is meant for a 3" so it is hard to get it tight.

Go snorkel with it!! Probably a bad idea for DD but, damn. You're in bad shape for space. Lol

I used a 45* 4" diameter intake only going down about 6" due to a similar issue. It points it right past your traction bar towards your wheel well. You don't need a CAI, just something to help with spool characteristics, as you only need a couple of inches in length to be effective

It will come in handy regardless.
