Editing Cold air intake (section)

==Construction==
Intake systems come in many different styles and can be constructed from plastic, metal, rubber (silicone) or composite materials ([[fiberglass]], [[Carbon fiber reinforced plastic|carbon fiber]] or [[Kevlar]]). Tubing can be steel, stainless steel, aluminum, plastic, or a combination of materials.<ref>{{Cite web |last=Ceridono |first=Ron |date=2016-04-29 |title=Building A Cold Air Intake System |url=https://www.motortrend.com/how-to/1956-chevrolet-pickup-building-a-cold-air-intake-system/ |access-date=2023-09-05 |website=motortrend.com}}</ref> The most efficient intake systems utilize an [[airbox]] which is sized to complement the engine and will extend the powerband of the engine. The intake [[vehicle snorkel|snorkel]] (opening for the intake air to enter the system) must be large enough to ensure sufficient air is available to the engine under all conditions from idle to full throttle.

The most basic cold air intake consists of a long metal or plastic tube leading to a conical air filter. Power may be lost at certain engine speeds and gained at others. Because of the reduced covering, intake noise is usually increased.

Some intakes use heat shields to isolate the air filter from the rest of the engine compartment, providing cooler air from the front or side of the engine bay. This can make a big difference to intake temperatures, especially when the car is moving slowly.<ref>{{cite web|url=http://strikeengine.com/air-filter-heat-shields-3 |title=Air Filter Heat Shield Test – Do Heat Shields Make a Difference? – StrikeEngine |date=22 July 2011 |publisher=Strikeengine.com |access-date=2013-10-14}}</ref> Some systems, called "fender mount," move the filter into the fender wall instead. This system draws air up through the fender wall, which provides even more isolation and still cooler air.
