As an example, before I had my S2000, I was driving a Mazdaspeed Protege. At Gainesville Raceway one day, I had fairly consistent exit speeds from the chicane after the decreasing radius sweeper in the 40mph range. 1 month later, I went back with no differences other than a different BOV. My exit speeds were closer to 45mph then, and had dropped my lap times by around 2 seconds on average.

Did the BOV make me go through the turns faster? Of course not. After reviewing recordings from my in-car camera, I determined that I simply was apexing the decreasing radius later which allowed me to turn much less sharply through the chicane.

My point is that, unless you have a lot of seat time on a course, small changes are mostly negligible as an increase in driving skill or track familiarity. I'm not saying it's impossible, I just doubt that the intake was the one distinguishing change.

Also, were both setups (OEM vs K&N) done on the exact same day, with the same temperature, humidity, track conditions?

Been to Laguna Seca 4 times and consistently hit 103 on the straight with high 1:50's lap times and over a dozen track days total. conditions were the same wednesday as they were in november when i was there, cool and dry. this time, consistent 108 on the front stretch. i was also really close to tapping the limiter approaching turn 6 and that never happened before either. i'm running the same set of tires as november which was my last track day. if in 3 days there i can do a consistent speed and then i add an intake and suddenly i'm much faster, then i am convinced that the car had more performance.
