During the dyno day that we were at last week, had a look at Greg's turck. Other than the monster Bassini tip that he had on his Dynomax system (nice!), I was looking at the AFE air filter that he installed. The element is a K&N. Same one that I have on my FIPK. How is it then that the AFE is accepted as a good thing and the K&N is not? He did not have the sock on the filter, but other than the plastic air intake tube on the K&N, they appear to be identical filter elements. Curious, no?
