Compact air filter for the GT42, pics within.
I looked everywhere for a good filter to replace my compact(5.5Long with a 5 ID opening) K&N cone filter that was now too long because I messed up a measurement when fabbing up my truck manifold kit.
My search led me to place in Australia....damn those aussie guys have some good products over there
I bought a custom pod filter that specs out at
127mmx100mmx180mm or 5in x 4in x 7in for us Americans.
Flange id x filter thickness x filter width
Here are few shots of it on the car/turbo and a few of the box and prefilter as well. You can see the reinforcement inside the filter both top and bottom. These were designed with FI in mind. No fear of it collapsing.
It has more surface area than my ol K&N. It also breathes from the top as well. Can't beat it for how compact it is but offers quite a bit more surface area too.






Ran me just over $100 shipped, for the filter, pre filter and a bottle of oil treatment and 20 bucks for shipping from AUS to here.
It shipped out on the 18th and I got it today.
So for those who are stuck with limited space, go to the site listed on the box and go under custom pods. You'll find a ton of filter sizes for almost any turbo.
Hope this helps a few of you out there, no more turbo screen for me

I'd be in a real jam if I couldn't find a filter especially since the car is driven daily. I was shittin bricks when it snowed for half a day over here and I had to drive home from work in the instant slush with nothing but a mesh turbo screen and a waxing bonnet over that.....it was all I had in the car
I was stoked to see that the filter showed today no more fears of running around in dusty, snowy, rainy conditions again.
Thought i'd share a great design for a filter instead of those hard to place cone filters.

I told em it was a turbocharged app, and that the airfilter would be mounting directly to the turbo itself for space limitation reasons.
They rec'ed the one I got above.
But i'm not really worried on CFM rating, I was just worried about having an airfilter on the car since its a DD. The prefilter is probably overkill for the street, but it tends to get dusty here in albuquerque with all the road construction going on.
For all out racing purposes i'll slap the turboscreen back on the car, so that'll be the best of both worlds. Filter for the street, and screen for high flowing track fun.

I asked them how it will fair with a turbocharged 383 making 800hp...still waiting on response.

PSJ it'll do fine driving around the city, if you are going to a full tilt street race or hammer on it at the track, don't run anything that might be a restriction to the turbo like a filter... run a mesh screen of whatever mesh material that would make you feel safe or run nothing and have no doubt about power production

I really don't see the turbo sucking this filter in as its bonded to the flange and it has a thick metal mesh cage with support up top to keep it from caving in.

But yeah if you want something that'll flow a ton in a tight space you won't find it in a air filter that is small...just too impossible with limited surface area. Go big or go home goes hand in hand with high flowing air filters. Try to get a foot long 5 inch ID filter in the tiny space that I have, its not going to happen.
That was the reason for my post, the GT42 is huge with a huge 5in opening on the compressor housing. Packaging is tight so I had to come up with a filter of some sort because my car is driven Mon-Sat every week and to run no filter all the time is not good in my book.
So to those who are compromised on space and need a filter for everyday driving, look at these filters as they sit right on the turbo and are compact with a lot of surface area
K&N's just stick too far out and my old one didn't offer as much surface area to breathe through for my turbo.
So its a compromise, filter for the street, no filter for all out WOT fun. All it takes is a flat head screw driver and your turbo is breathing easy at the track. No need to over analyze everything.

The P/N's are wrong! If you order, tell them the size you want and not the P/N. They said their columns on diameter and length got switched, so again, dont order by P/N. Ask for the size you want.
