Awesome!!
Had a check engine light come on for cam shaft position. Did some research online about the specific code and found that I could be due to sludge in the engine. Added this and ran for about 30 minutes and then had the oil changed. The light never came back on and the engine is running smooth and quiet. Will definitely use again.

Good price!
These are your basic filters for jeep or Chrysler vehicles with the regular oil change interval mileage. Cheaper than Autozone for the price.
