I recall an old issue of MCR reporting on a GTO Nats visit. A local dyno had a 389 Tripower running dyno pulls for the entertainment of visitors. Someone asked if the K&N filter was worth it and the operator said he didn't know. One spectator went outside and took the K&N filters off his car and replaced the paper ones on the dyno engine. The 389 picked up 10hp. I've used the regular ones on my Quadrajet equipped cars. Yes, rinse gently and reoil and they look the same.
