nice quality
Size: 1.9" x 9.9" x 11.4"
I happen to be a fan of K&N air filters. Fit perfect in my vehicle. Seems like a much nicer quality filter than the cheapo filters from the parts store.

Great purchase!
Size: 1.9" x 9.9" x 11.4"
This has worked out quite well. I have had it since 2023 and have been cleaned thru about 6 maintenance schedules. It's been 2 yrs and it's in great shape. Worth every penny.

Really filters the cabin air
Size: 1.9" x 9.9" x 11.4"
K&N filters are always a cut above. Can’t say the same for service/support after the sale.
