Aluminum dryer vent warm air intake to the back side of the snorkle. The front is blocked with pipe insulation noodles and aluminum tape.

The vent entrance is hanging just above the exhaust heatshield between oxygen sensors.

I was seeing intake air temps very slowly rising to 120F over 10 mile commute with 70F or lower ambient temps and full grill blocks with just the back of the snorkle open to underhood air temperature.

The next step is adjustable shutters on the front.

Mirror deletes, 80% grill blocks, wheel covers, 50 psi tires = 6% better MPG avg. over a year. Wheel skirts overcoming ethanol winter fuel mpg losses and more!
