Pipe and tune, made for the same machine

A new pipe flows more air. On a fuel-injected machine the TFI Power Box adds the fuel to match. We make both for your exact machine, so the tune is right on day one.

Will it fit my exact machine and year?

Every product page states the make, model and year range it fits. Save your machine to the Garage and the page confirms it for you. If your year is outside the range, the page says so and shows what does fit.

Do I have to tune it?

On fuel-injected ATVs and UTVs, yes. A pipe changes airflow and the matched TFI Power Box keeps the mixture right and the warranty intact. The product page shows the box built for your machine. Carbureted machines re-jet instead.
