| + | Hi fellows, techinspector1 here. I'm still tech inspecting at Firebird International Raceway in Phoenix and want to pass on some basic information on the subject of cold air intakes. I constantly see installations that have been done with K&N and other filter assemblies with the filter in the engine compartment, usually right behind the radiator. | ||

| + | Common sense should tell you that you are picking up 200 degree air right behind the radiator, but I guess common sense isn't all that common anymore. Run your ducting to the outside of the car to pick up cooler ambient air and you'll pick up power. For each 10 degrees of lower air temperature you duct to the intake, you pick up an additional 1 percent power (rejetted of course to take advantage of the denser air). Here in Phoenix where the ambient can easily be 100 degrees, a change from underhood air at 200 degrees to ambient air at 100 degrees can mean a 10 percent increase in power. | ||
