Every morning I drive about 2 hours in traffic, so I decided to try this product. help improve my IAT (Intake Air Temperature). After properly installing this product on my AEM cold air intake and testing it with the new Honda s300v3 app for a week, I found that it only took 15 minutes longer than usual to reach 59 degrees intake temperature. Celsius, this is the highest daily temperature when the air conditioning is on. So I don't really think it's worth buying.
