Convenient and economical
I can't believe that I've paid $60+ for years to have my filter replaced. The money that I've spent is mind blowing.
The replacement actually takes 2 minutes! Quality is amazing and it lasts just as long (maybe longer) the dealer's and repair shops version.
Helpful tip: Do it yourself for far less.

Very Good At Capturing Debris Of All Sizes
I have been using this for my 2015 Acura RDX for several years and each time I replace it, the old filter seems to do the job in capturing big and small debris.
