Post Custom Mounts for Cone filters 98/99?

Hey everyone!

I'm just curious. Anyone have pics of mounts they've came up with, or are using, for the MAF sensor when using a conical filter?

I just got my K&N, and plan on putting it in today. Hopefully, I'll have something by this weekend in place to hold the MAF securly, while keeping the vibrations to a minimum.

I'll post pics when done. Just tryin to get some ideas?

made my own out of aluminum for my K&N cone filter. its basically an "L" bracket from one of the bolts on the MAF to the body. Had it on for about a year with no problems.

Kartboy Kustoms makes an adapter for this purpose.

You can find them in the links section.

well, just installed the K&N. AZScooby sent it with a plate to mount the filter to the MAF, then a odd steel bracket to do something with. I ended up cutting the bracket down, and mounting it to where my horn for the alarm was mounted. I'm not too hot with the mounting arrangement, since it just seems too flimsy. I'll get ahold of RalliSpec, and see if I can get just the mounting plate they use for their intakes. Or maybe make something from aluminum.

Hey, is it normal for the K&N to "whistle"? Pretty cool sounding, but I'm not sure if that's normal?

I'll have pics of my ad-hoc mount soon.

Mav1c i dont have any pics of this but... Basically i connected one side of the bracket to the bottom bolt closest to the fender (on the MAF). While the other side of the bracket is connected to the passenger fender just to the left of the horn (in the second pic). Thats about it. The aluminum piece is about 1 and 1/4 inch wide and 1/8 thick and about 5 inches in length, and i polished it just because.

In the next one, you'll see the mount a little better. see the arrows?

I'm not too comfy with the mount though... so I'll hopefully whip up a better mount this weekend.

Kartboy made my adapter.

I secured it in 2 places and it's very solid. I've driven it about 18K and a few auto-s's too with no problems. I did keep the stock torque box though:

I have cone filters with MAF adapter and brackets for sale on my site. I also have a new machinist for the MAf adapters and brackets for a cold air intake similar to Peaty's, and they will hopefully be available soon.

See www.ImprezaRS.com

ImprezaRS - that setup is from you. I ordered it last week, when you did the group buy on the 00/01 intake.

I love my kartboy MAF addapter. He Peaty, how well does that Reactive filter flow? I kind of want to get one but the surface of the filter seems a bit small.

The Ractive blows in the stock configuration but I've got a really cool intake using a Ractive coming soon... give me about 2 weeks.

P.K. - that's not what our experience says about the Pro1 clone of the Ractive filter that we used...

hacman - the cone kit you got comes with one bracket didn't it?

Uh, no Larry, the Racitve [as it was meant to be used] sucks. I've had several intakes on my RS and in standard configuration attaching a Ractive is the worst of all of them. Have you checked out how they get dirty? All the dirt accumulates in a ring around the base, which might have something to do with it being the shortest distance between the wall of the shield and the mouth of the intake right at the base. As that gets dirty your flow rate decreases even further. Worse, the Ractive is an anti-velocity stack design in that it gets larger before it gets small, and when it does there's only a tiny little chamfer on the mouth of the neck. Looking at the way it gets dirty it must be the case that a lot of the air is flowing parallel to the base! That's poor design and it blows airflow-wise because of it.

There is a fix for all of this... I guess I'll let the cat out of the bag. Remove the base altogether and use a 4-3 reducer to attach the snout of the Ractive to the MAF adapter. The inverted cone then apes the PRM design except that it's bigger than a PRM and it decreases steadily from 5" to 3" rather than going 3"->3.5"->3" as the PRM does. I hope to have pictures up soon, but let's just say that some preliminary testing indicates that this is going to be a really wicked intake.

I haven't had any problems with my setup. Maybe because I still use the second airbox (with the gasket installed) I don't have any flat spots and it pulls easly to redline. I've only cleaned the filter once and the dirt appeared to be evenly distributed. It wasn't all that dirty looking though. Still when I cleaned it a lot of brown gunk came out.
