K&N oil filter part number for 340?

It’s the right part number. I run the K&N PS-2004 on my car, but I run mine without the 90 degree adaptor. The dimensions are the same on both, the PS-2004 is the “performance silver” and the HP-2004 is the “performance gold”. I haven’t had any issues with mine, I run Brad Penn 10-30 in my 340. There was some kind of rhyme or reason why I decided not to spend more money on the “gold”, I remember looking up all the particle filtration and performance specs before I decided but honestly I don’t recall why I choose the silver one anymore.
