A smooth radiused air inlet is generally a good idea and actually must be used to test things like intake ports on a flow bench. The filter acts a flow straightener itself but it does have reduced and somewhat sharp edge at the outlet so the velocity stack design may have some merit. A flow test would tell for sure.

TB spacer?? for what engine? It looks nothing like any of the TB spacers I've ever seen.

I did not intend to say it looks like what, but the function would seem similar. TB spacers are used to increase velocity of air flow. So to reword my statement.


It would seem as though the resulting effect of using this would be similar to that of a TB spacer. Maybe that'* judging a book by it'* cover. Give it a shot. I'd like to know the results.

If anything I could test it by recording my maf readings. I'm also trying to figure out if i'm going back to a 3" intake pipe too. :?

*&B Filters already use a velocity stack effect. It is'm as drastic as that but alot better then K&N.

I searched thier site and couldn't find any info on that. Do you have any pics?

I know what he'* talking about. I've seen pics of it. Mike, I'd be really curious to see what your MAF readings are with and without it, but I would suppose it would only make a difference if you're outflowing your current setup, or if you aren't laminar enough in flow right now.

Overall performance might not be affected much, however your throttle response might definitely see an improvement when you go WOT.

No sorry and I will not be able to get any pics of it any time soon because my Bonne is in Chicago right now. My setup is basically the same but a 6" x 9" Cone filter with a 4" inlet.

Quote much?

Damn... I didn't think I was that tired. Working 12+ hours a day 6 days a week.
