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.
