I used to be gung ho on using K&N filters and bought into the hype about their increased flow. The truth is the stock H2 filter does a better job than any aftermarket filter at filtering harmful fines like silica (sand) out and should not be replaced with a lesser micron filter.

The stock intake tube also includes a splash container to partition any water away from the intake that makes it past the MAF. You don't get that with the aftermarket tubes.

At the strip or for a street car, K&N is fine, off road severe duty conditions, your stock filter is your friend. Don't bother posting about the Baja 500, those engines aren't expected to go 100,000 miles.
