I'd say your best bet for finding something like this would be in the plumbing section of most hardware stores... They will either have it, or know who you could talk to to get one...

I already rebuilt the back of the airbox using small plastic boxes (although one or both may need to be cut down to fit...).

Notwithstanding the possiblity of having to modify the backs a bit, I'm hoping to have these installed for testing this weekend, with dynos sometime next week.

The velocity stacks are molded into the inside of the filter flange, so it's kind of hard to get a clear picture... bascially, it's just a nice smooth transition from the inside of the flange to the inside of the filter.

Between that and the open top (note it isn't sealed, but has a section of filter), these X-flow filters are pretty awesome!

Should pick up some power over the panel filters, but I'll let the dyno decide if this was worth all the trouble or not...

Essentially, I am rebuilding the back of the airbox to allow more room for the K&N filters. Still looks a bit rough, but it's coming together...

Will probably have to cut about 1" of material off of the top part of airbox back I've built for the passenger side intake to make room for the power steering fluid reservoir, but this gives you an idea of what I'm attempting to accomplish...

So far, so good -- with a bit of insulation material to make up for imperfect sealing between plastic components, should maintain OEM heat shielding and cool air ducting, while addding a better flowing set-up that would be achieved with just a panel filter.

Moreover, after I clean it up a bit, to a casual oberver it should look pretty stock once installed.

More updates soon with dynos to determine whether it was worth all the trouble...

You might be looking at some turbulent air by using a cone filter inside a square box. It looks like air will come in and flow around the cone filter too and cause some turbulance going into the filter. I dont know if that will matter much but maybe using a square filter is still best. What I would like to see see is how much air does the engine require at WOT? And how much air does said filter flow. Using my Cobb tuner deivice I got a reading of 400+G/S on my K&N drop ins. They flow more than that so Im thinking the engine is getting all it asks for.

Hmm. I hadn't thought of that.

Well, it all remains to seen whether or not this makes more power... however, if the stillen short rams made decent gains (over K&N panel filters?) then so should this -- it's essentially the same design.

Whatever the results, I'll share all the details.

sounds good, maybe you can think of a way to funnel the air to the intakes and not let it flow around the back end of them.

Is that the problem? I suppose I can just cut it down or build something that is more funnel shaped to form the back.

Hmmm. maybe will not install these just yet -- dang.

Jordo! · 11-05-2010, 02:33 PM

Okay -- the rear box idea did not fit...

So I went with cannister type shileding. Still managed to get the OEM airbox to fit, providing additional shielding, use of the OEM cool air ducting, and the OEM mounting points.

Looks pretty stock without careful scrutiny. Will be dyno testing either today or early next week to see if this was all for naught...

LightsOut · 11-05-2010, 04:38 PM

in for dyno numbers

Jordo! · 11-05-2010, 05:51 PM

Failure! Lost power everywhere!

Oh well... back to factory airboxes for now. Might try replacing the post MAF hoses and/or different ducting instead of reusing the factory airboxes.

Sigh.

EDIT: Yeah, just ordered HPS hoses. I'll try that next. Dynos to follow...

6spd · 11-05-2010, 10:16 PM

in for dyno results of the tubes, im damn near pressing the order button on a set!

Rooskey · 11-06-2010, 12:44 AM

If you never try you will never know. Good to see someone thinking outside the box!

Ironically, I probably lost power for thinking inside the box (so to speak)

I'll try this set up again with larger filters and some modshack-style ducting. I think the major flow killer was trying to reuse the factory airboxes. Suppose I should have tested it with out the airboxes before dismantling, but was so annoyed, I just wanted my 10 whp back

Oh well... back to the drawing board.

I was thinking the same thing. I'd go with square K&N's. Things are looking good, Jordo! Have you contacted Modshack, he might be able to give you some good ideas.

Also, Cobb no longer makes the intake tubes.

You can get the HPS post MAF tubes from Corsport.
