I’ve read somewhere that by installing an open type cone filter you would lose low RPM torque but gain top end HP? Is there any truth to this? I’ve recently installed a simota open type filter and noticed that at low rpms the engine lost some “pull” but at the same time I get better fuel mileage. I then re installed the original airbox and filter after a month as most of my driving is around town. What I have known is that when you get more air in the engine it gets more power, but how come you also lose low end torque?
