Ted also mentions that it's not the filter that's the restriction, it's the box itself. I have no reason to dispute Ted's claim, but if you note the spreadsheet picture from the first post, changing filters, or removing the filter all together DOES allow the stock box to flow more. It's not as big of a restriction as people think.
Back before I started playing with these filters on the flow bench I would have agreed, but everytime I put the S&B filter on the bench, it flows extremely well despite it's looks. |
I had tested Stock air box with stock filter against K&N against No filter and as I recall, there was no more than 1 RWHP measurable difference.
Engines do not flow like Flow benches, there are both Pluses and sound waves involved that affect HP.
Great Job on the Testing
Ted.
