Yes pf64. Threads are the same. All I'm saying is for $7 it is worth a shot.

Short answer: acdelco oil filter 12706595 Now the rest of the story: this a $7 filter made for the corvette. I have a 2009 Silverado 5.3 with the dreaded afm. As soon as my truck would get up to temp the pressure would drop out to nothing. I changed out the oil pump, the o-ring, and the oil pressure sending unit (4 times). I finally called my awesome mechanic to see about an engine swap and he told me to try this first. I could not believe it, it totally works. Now my truck starts out at around 45 psi at start up and after it warms up it stays around 40 at 2000rpm and goes down to 20psi at idle. Can drive all day no problems. I don’t know the why or how but for $7 you have to give it a shot! And then spread the word!! Make sure to respond to this so others know it’s real and works.
