Buschur Air Intake vs. Stock Box
Wow I feel patient now sitting down and reading the whole thread.
IMO, the buschur filter is nice but if it causes problems go back to stock airbox. Ta da! That's it. That wasn't so bad now was it?

Well I have to say that I have mixed feelings about the intake (I ordered it just to evaluate): (1) I like the quality of the bends and welds -- very nice, (2) the pipe should have a bung -- easy change, and (3) I personally think BR should use a different filter for street applications (flow is good but particulate filtration is not great).
Not all pipes are equal quality. I am no BR fan boy, but the bends and welds are very good. I don't understand why Dave uses SS instead of aluminum (pro race cars -- F1 to rally have used aluminum), but it probably does not really matter for most of us. Dave nice stuff, but add the bung please

PS - I have a new BR intake and UICP never used For Sale if anyone wants one...

Come to the ECUFlash forum and we will help you out. Make sure you have good logs of your fuel trims at idle and cruise and it also would help if you have WB data.
This should be a relatively simple fix. Also, do you have the breather hose that goes from the valve cover to your turbo intake pipe still in place or do you have one of the Bushcur breather filters? If you have a breather filter, get rid of it now and put the breather hose back on.
Open a thread in the ECUFlash forums. You should get plenty of replies and I will jump in where necessary.

Edit: I am assuming that you have an ECUFlash cable or access to one, maybe from a friend. If not, then it's your call whether you wan't help fixing/tuning this yourself with an ECUFlash cable (buying one) or to bring it to a pro tuner in person. Either way, I would still recommend posting your question and logs in the ECUFlash forum. This may be a simple hardware fix and need additional tuning (like the breather hose).

If you would please be so kind and elaborate as to why you think the filter isn't good for street use, I'm just trying to learn your point of view. Thanks
I can't give you data (unless you pay
), but I could probably get K&N or S&B to come on and provide all sorts of filtration data...

hey guys im new to this site and i have an 03 evo 8 i am looking to put the small battery kit n i read that u have to change the airbox to an intake any suggestions or recommendations on either one? thank you
The nisei upper intercooler pipes also let you keep the factory airbox as well.
Also, I should have clarified that I drive on freeways / areas that are very dirty / sandy, so for me a filtration system with better particle / dirt capture is important.
Again, I am in no way criticizing Dave's kit -- I like the pipes a lot. I spent $750 on UICP, BOV, intake system -- is that a lot yes, but the quality is what I expected. The only thing I would change would be to add a bung and change the filter (both of which I plan on doing).

I don't believe the dry filter that is being used with the BR kit will filter dirt as well as a factory paper filter, a K&N wet filter, or an S&B wet filter. That said, it is probably one of the least restrictive filters -- unfortunately there tends to be a negative correlation.

I can't remember if I could still use my stock air box when I installed my mini battery, but I don't see why it would be an issue.
