Over the past year we have conducted extensive dyno testing on a variety of high-performance vehicles to determine exactly how much power you can gain by reducing inlet air temperature. Frankly, the power gains are stunning – particularly on older muscle cars that typically have a round air filter on top of the carburetor that draws air that has been pre-heated by the radiator and exhaust.

By ducting cooler ambient air to the engine, you can dramatically improve performance. The more powerful your engine (and therefore the more air it requires, since engines are basically big air pumps) the more it is effected by inlet air temperature. Here are some examples.

On a typical hot summer day, underhood temps in a classic mucle car can be as high as 190 degrees. By reducing air inlet temperature 50 degrees - to 140 - the engine gains 25 horsepower and 26 lb/ft of torque. Dropping air inlet temperature to ambient (in this case 80 degrees), the formerly 300hp engine becomes a 360hp engine!

Performance improvements are even more impressive on a 350hp engine - which gains 70 horsepower and 75 lb/ft of torque when air inlet temperature is lowered from 190-degrees to 80-degrees. Think about that... there are very few ways you can add 70 horsepower to your engine without tearing into the internals or adding nitrous.

Ever wonder why your car feels so much faster on cold winter mornings than on hot summer afternoons? The more power you make, the more your engine is effected by the density (temperature) of the air. Cooler, denser air means more oxygen is packed into the combusterion chamber on every compression stroke of the piston. The more powerful the engine, the great the improvement in power. A 500 horsepower engine can see a 100 horsepower gain from a 110-degre inlet air temp drop. But even a modest 30 degree inlet air temp drop picks up 24 horsepower and 25 lb/ft of torque!

The Easy Access Oil Changer relocates your oil filter to the top of the engine compartment where it’s easy to change without a mess. The kit also includes a filter relocation bracket that holds an extended oil drain line attached to your oil drain plug, a 12v pump that plugs into your cigarette lighter to help pump out all the old oil without getting dirty on the ground, and a variety of fittings to make it work on nearly any vehicle.

Other advantages include the ability to run large capacity high-performance oil filters and the ability to move your filter away from headers or other heat sources that can cause burns during service.
