Excellent filter. I recommend it
Size: One Size, Style: Select
Arrived on time as promised. I was able to install it easily on my Jeep Cherokee with 3.2L engine. Good instructions and the part seems to be of good quality. Four Stars only as I have just installed it. Filters are passive components, usually can't tell of their long term quality or reliability unless they leak or cause immediate problems. I recommend this part.

Awesome filter, my engine told me it loves the fit and ease of installation. It also it very good value for money as they aren’t expensive and you are getting a high value for the money. My engine also told me it’s getting slightly better fuel efficiency as well.
