Stealth Airbox Mod
So the Perrin will not fit.
I am using a samco intake pipe thats already trimmed about 3/4 inch to fit the filter as it sits. There is only about 4 1/2 inches of space with the Vibrant adapter that is required. The Perrin is a full 7 inches tall. One would think I could just trim the intake pipe a little more but no way will I get 2+ inches without totally relocating the MAF not to mention the connector to the MAF would not reach at that point. OMG filter here I come!! Otherwise the mod to the box was easy and only took about 30min start to finish.

This is my first time posting pics so bear with me if I screw it up. As you can see there's not much room. Could get maybe another inch before I would not be able to connect the MAF sensor.


Pretty good size filter. I apologize for it being sideways.
The OMG speed element filter is at a good price right now so I'm just gonna roll with that. Might give up a pony or two but I much prefer stealth over all out power.

Good luck with that. Like I said before you will end up with the MAF too far away from the wiring harness to reach. I just ordered the OMG filter. It's cheap so not much to lose. I'm not much for wanting to hack something too much just to make it work. Not to mention I am kinda getting tired of the oiled filter thing especially when you could pick up another OMG for under 50 every so often.
I'm trying to make it work because the K&N Small (Which is almost the same size as the OMG filter) didn't show fantastic numbers from Kracka's air filter shootout:
Buschur: 378whp/361wtq (old style, no longer available)
Perrin: 376whp/345wtq
Amsoil: 374whp/344wtq
Vibrant: 371whp/351wtq (current style Buschur air filter)
K&N - FIPK: 369whp/355whp (comes with Typhoon intake kit)
Apexi: 367whp/357wtq
K&N - small: 367whp/346wtq (caused more knock than others)
In this shootout alone it was a difference of 11whp/15wtq.

Get a omg filter if you want this mod to work. if u want the box on u need the OMG filter if u want other filters u will run no box that's about it
