Intake

For most builds, this is where it all starts. Intake parts are typically inexpensive, but give great bang for their buck. A proper intake will free up HP, make your car sound better, let your engine breathe more efficiently, and can even free up some extra gas mileage. There's typically no shortage of options when it comes to intake upgrades, and it's a great place to start if you're not sure where your project will end up.
