I have had this airflow system installed on my Titan since I bought it in 2004.Cleaning the filters is easy enough, but they take forever to dry. So I always have a spare clean filter. To swap out.

Dans mon auto, il est trop gros et prend extrêmement beaucoup de place. C'est pour un camion et non voitures sport turbo.

Perfectly fits my 2005 Nissan Titan AEM Brute Force CAI. The old grey filters I had on hand (one on the truck, one in standby for when the other needed to be cleaned) had rubber dry rot (expected after 12 years). Popped the old one off, put this one on and it fit perfectly. Comes with a new clamp too so no need to keep the old one.

Very good quality. A bit expensive for what it is. But you pay for what you get.

My old filter had started to dry rot and fall apart. I did some research and found this one. Good price and perfect fit to replace my old one. You can't tell from the image, but it is slightly cone shaped (as was my original one).I can't tell if there is a performance increase or any fuel mileage gain (over a previous similar filter). But I really wasn't expecting one.I also bought a dry flow air filter wrap to go over this (item [...]) which fit like a glove. Again, ti was a replacement for an old one that started to just fall apart.All in all, this is what you expect if you are buying this part number. Seems high quality. Installed easily. Runs well.

Easy to clean, improved mileage(with Brute Force kit) about .5 to 1 MPG on Nissan Armada. Power increase is negligable.
