Big Gun 11-19 Suzuki KING QUAD 500 Power Box

Big Gun is known for making performance parts for powersports vehicles, and their TFI Power Box is a popular way to get more out of your Suzuki King Quad 500. This module is designed to optimize your ATV's throttle mapping and fuel delivery, giving you a noticeable boost in performance without messing with the stock ECU map. It's a straightforward upgrade that makes a real difference in how your machine feels when you twist the throttle.

What this box does is sharpen up your throttle response, making it feel more immediate and responsive. You'll also notice smoother power delivery, especially in the mid-range where you often need it most for climbing or getting out of tough spots. Big Gun builds these with durability in mind, so they're rugged and sealed against weather, ready for whatever conditions you ride in. Plus, you don't need a computer to make adjustments; there are buttons right on the faceplate to fine-tune things on the fly.

This is a plug-and-play unit, meaning it installs in minutes and doesn't interfere with your ATV's original computer. It's especially recommended if you've already upgraded your exhaust system, as it helps get the most out of those modifications. Just remember, this part is not CARB approved and cannot be shipped to California.
