Wws: u are aware that a warm air intake just takes air don the engine compartment and not from the fender like a cold air right? The warm air intake only has engine bay ambient temp. It's not "heated" like the older cars on a cold start up. And intake temp is not going to heat the cat or O2 sensor rather its hot or cold. Hot air goes in engine, comes out hotter... Cold air goes in engine and come out just as hot. What helps heat the O2 sensors are build in heaters. Plus the extra fuel In the exhaust heats the cat
