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.

Effective

This worked wonders on my car’s performance! After one use, the engine started idling much smoother and the throttle feels more responsive. A very high-quality German-made product.

Great for All Cars but Especially German Cars
Size: 300 Milliliter
I use this in our used VW we bought and it helps keep the carbon build up down with their direct injection feature. I pair it with their oil additive which helps lubricate the rings so they don't stick as much.
