Was thinking about finally buying a ZZP intake the other day and happened to come across a K&N intake for the Regal (part no. 69-4532TTK). I had no idea K&N even made one, since I don't recall ever seeing anyone on here discuss it. Not sure if it's relatively new? It's the same price as the ZZP, but it has a heat shield around the cone, whereas I don't believe the ZZP does. I know there have been debates on here in the past as to whether the intake sucking up hot air makes a difference anyway due to the intercooler, but I suppose the heat shield can't hurt. Anyway, I ended up buying it and installed it today. The only problem with the K&N is that if you have a Turbo model, the alcohol sensor on the firewall is in the way and has to be moved over for the pipe to fit. ZZP has a bracket to relocate the sensor (shift it over to the left a couple inches), but the K&N does not. In fact, the directions make no reference to the alcohol sensor being in the way. Other than that, it looks good and is noticeably louder than my AEM dryflow cone filter on the stock intake tube. Wondering if anyone else has the K&N?
