I ran a K&N against the 5vz for all of two cleaning cycles before I went back to paper. The only "seat of the pants" gain was on the first trip after I dropped it in. Within a tank of gas the computer adjusted for it, and within six months it had fouled the MAF and throttle body so that I was losing performance. OEM filters all the way.
