RPO/Knp Code in Engine Oil Coolers and Kits

2005 Yukon Denali Engine Oil Cooler Line! Check your glove box for the RPO KNP code! No more oil loss! Check the oil level after installation, the oil pressure gauge may also need to be replaced, mine seems to be bouncing up and down from the oil gauge on the dash again, but wait until it gets really crazy, replacing that little switch is an expensive job !

Pros
  • GM Recommended Replacement Part for Your GM Car's Original Factory Component
Cons
  • Little Stuff
