Not at all. The only thing it gave me was...1 additional mile per gallon...1.
Exactly
On older trucks or even trucks that use a MAF sensor vs a MAP sensor maybe. A colder reading makes the MAF think there is more airflow than what there actually is since it’s adjusted to the stock reading. Our trucks come factory with a cold air intake setup. Most aftermarket intakes mount to and suck through the fender same as factory. Only difference is the larger filter which unless needed is not beneficial. Heck the 6.4 uses the same size filter and throttle body as the 5.7 and makes 90 more HP? Over the 5.7. Go figure. So performance wise the stock airbox can flow well enough for around 500hp. Isn’t that crazy good for a factory setup. And the air is fairly cold. Some of the aftermarket intakes “seal” to the hood and still draw air through the factory hole or in some instances like the K&N to name one are actually sucking in air from the engine bay because it doesn’t seal to the outside air. Not very cold now. Heck I’m running the 6.4 intake manifold and 6.4 airbox drawing air from a snorkel. My air is 5-10° above ambient while cruising. Why? I’m drawing air from outside directly. Before the snorkel my air was still 5-10° above ambient. Why no difference? Because stock draws air from outside the engine bay.
