Ramair Filters utilise the top-quality components in all their kits see below for what this kit will include: Heat Shields should be used with an induction kit to ensure the intake charge is not heated by the main engine bay. The cold air feed was routed to receive air from the bottom of the car but the feed ran close to engine and exhaust.

An open cone filter could give less power than standard air filter, if standard air filter is not a restriction. I tried air filter heat shields in 4 different designs to see which was the most effective at reducing inlet temps. We want to know 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. Urban driving: hp gain max: + 6.8hpwhen using heat shields – (intake temps 14C lower with heat shields over standard air box). Open road driving: average gain + 4.38hpwith heat shields – (intake temps 9C lower with heat shields over standard air box.)

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%. Urban driving: average gain + 5.84hpwith heat shields – (intake temps 12C lower with heat shields over standard air box). Design 4 gave the best results. Isolating filter completely from engine bay but leaving the filter exposed to the air entering the engine bay. No cold air feed was necessary. This induction kit will increase the airflow into the turbo while increasing engine noise over the restrictive factory air intake system. This kit includes everything required for the fitting of the induction kit.

The idle temperature was taken by running the engine up to operating temperature with the bonnet open. 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. For every 10C increase in intake air temps, air density is reduced by 3% and therefore horsepower is reduced by 3%. So while an induction kit will make a better noise and make then engine bay look better it may not increase peak horsepower if it is not properly shielded from the heat of the engine bay. Viper Induction Kits/Typhoon Induction Kits and other Cold Air Intakes CAI. Heat shields should surround the cone filter an ALL sides, except the side facing the front of the car so the filter can receive air when the car is moving. Isolate from warm air that has passed through the radiator if necessary.Ducting routed next to the engine should NOT be used as the ducting is heated by the engine/exhaust. The heat soak from the engine was making the feed incredibly hot and therefore heating the intake charge as it passed through it.
