Review on K&N Engine Air Filter: High Performance, Premium, Washable, Replacement Filter for Toyota/Lexus/Mitsubishi 🔧 (Highlander, RAV4, Sienna, Avalon, Camry, ES 350, NX300, Rx350, L200, Triton) 2010-2019, Part Number 33-2443 by Ronnie Dunn

Toyota 4Runner 2010-2020 already delivered with COLD AIR INTAKETS! The OEM air intake draws in cold air from the outside and introduces it directly into the engine. All you need is a K&N air filter. This filter is the ONLY difference between OEM Air Intake and TRD PRO COLD AIR INTAKE. On the freeway, my 2014 Toyota 4Runner SR5 Premium typically gets 19-20 mpg. But with this filter, along with BLASTING AC and music, I can get 21-22 mpg. This filter has really made my car run smoother. For example, if you're going in place, just give it a little throttle, then give it more when you find the engine isn't running fast enough. Well, this filter solves that problem. This gives you about 5 horsepower, but the engine runs smoother overall. Each gear change is about 1.2 seconds faster.
