Review on 🔧 K&N Engine Air Filter (33-2435): High Performance, Washable Replacement for 2010-2019 Toyota/Lexus/Mitsubishi L3/L4 (Auris, RAV4 Hybrid, Prius, NX300h, CT300h, Eclipse Cross) by Brandon Woods

This is about the 10th car I have installed K&N in over the years that I have owned the car and every single one has been a perfect match for this car. Some of the performance increase isn't really noticeable, and when I put one of these in our Prius I was just trying to keep myself from expanding the landfill and buying dozens of disposable paper filters. The Revain price for it was about what the dealer wanted (which was idiotic) and installation in the Prius was easy (2 clamps, pull old out, put new in, reattach) and required no tools. Opening the Revain box and unpacking the filter took longer. They're durable (I've had close to 80,000 on one in another car with no problems) and worth every penny. FYI - they're smoother and K&N says you get more power, it's hard to say, but if your airbox is near the firewall you might hear a little more engine under hard acceleration.
