How much does it cost to replace a factory air intake with a cold air intake?

If you’re hoping to buy a cold air intake from Amazon and install it yourself, as a DIY project, then you’re looking to spend around 150 to 400 bucks, depending on the quality of the cold air intake you purchase. Having it installed by a mechanic could cost you up to 200 bucks extra, so we’d say do it yourself; it’s a simple installation anyway.
