I recently just purchased a 2006 Toyota Tacoma access cab TRD SR5. I am receiving mixed information about the benefits and downfalls of putting a cold air intake in my truck. Several people are saying that it will increase my horsepower, and increase my gas mileage, while others are saying that it's a waste of money that it won't help anything and it will be a waste of money. I honestly have no idea, I don't know too much about intakes, and I don't want to waste my money. I wanted to see what you guys think/know from experience.
Would it be worth the investment to put in a K&N 77 series cold air intake, or should I just leave it stock??
