Looking for great engine function? We don’t know any driver that doesn’t put engine efficiency and power at the top of his or her list. At the end of the day, however, achieving great engine function isn’t as easy as simply tinkering with the engine itself - you need to tackle the family of systems that support and engage with the engine if you want to get the best from your vehicle. With a Toyota 4Runner Cold Air Intake, you’ll be able to boost power in your great vehicle - guaranteed. What does an air intake system have to do with anything? Simple. The internal combustion engine in your 2005 - 2006 Toyota 4Runner depends on a steady supply of oxygen in order to function properly. Without oxygen, combustion cannot occur - and an engine without combustion is, not surprisingly, non-functional. Your air intake system, then, is responsible for supplying your engine with a great flow of highly-oxygenated air, thus giving you the raw ingredients you need for incredible power. With the right 4Runner Volant Cold Air Intake, you’ll have all the makings of a great air intake system and thus a great engine - guaranteed.
