Ruien Universal Air Intake Filter Cover Heat Shield Stainless Steel Carbon Fiber Cover compatible with 2.5-3.5" Cone Filter

Product Information

Most of these articles have temperature in Fahrenheit. (5/9 Celsius = 1 Fahrenheit), or just over half. The best figures from the articles above is from Banks Power which says that for a 5.5C drop power should rise by 1.8%. The idle temperature was taken by running the engine up to operating temperature with the bonnet open.

The cold air feed was routed to receive air from the bottom of the car but the feed ran close to engine and exhaust.

These gains solely take into consideration the hp gains due to lower temps and not the hp gains that the induction filter may also bring. The temperature was monitored on the route to determine the trends in the temperature changes, the max temperatures and minimum temperatures. Due to the laws of thermodynamics, anything that uses energy or performs work will inevitably produce a by-product in the form of heat. A car is no exception to this law and features various components which produce heat, some more than others. In most cases however, heat can have a detrimental impact on the performance of certain engine components. The figures used to calculate power gains due to the reduction in intake temperatures are taken from Banks Power, see link. Ramair Filters utilise the top-quality components in all their kits see below for what this kit will include:

The air filter heat shields can increase *power by4.5% (6.8hp)on a150hpengine. Inlet air temperatures dropped by 14C.To test the temperatures on the road, a route was devised which took in Urban Roads, Open Roads and Motorways. The heat soak from the engine was making the feed incredibly hot and therefore heating the intake charge as it passed through it. Cold air intakes and sealedinduction kits such as the Viper from Pipercross combine an induction kit with a sealed enclosure. This enables the engine to breathe in colder air than even the standard intake system as well as being freer flowing than the standard paper air filter element. However these sealed induction kits do tend to be more expensive than the open type induction kit but they should produce more power.
