That page explained the K&N formula to determine filter size
Ah...ok...I apologize for not being able to figure that out, there's a lot of various info on the FAQ, and the CA warnings are some of them.
But now I will ask you a question in regard to the formula, since I've seen it before but just wasn't sure where the 20,839 divisor comes from?
Another person calculated 190 cfm and K&N calculated 188 cfm, so very close and certainly close enough for me. This filter will allow 228 cfm, so it's well within what the carb needs. There are a number of K&N haters out there, so I wasn't sure if you were one of them or you were pointing out about the odd CA regulations, or what. That is actually a good point, because it's illegal to put a K&N on a newer vehicle that does require smog in CA, I had forgot about that.
