Good price and appears exactly like OEM
Color: 3 Set
Good price for set of 3 also includes o-rings for cap. After finding engine litter on a rocker lifter change wanted to run several filters in quick succession changing the filter every 100 miles and topping off the oil. seems to be working well and catching any glitter.

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.
