Is the Power Plus Cam Kit a good first upgrade?

Yes. It is one of the best first performance upgrades for Harley M8 riders wanting more torque and throttle response without a full big bore build.

Do I need Stage 1 before a Power Plus Cam Kit?

A high-flow air cleaner, performance exhaust and tuning device are strongly recommended so the cam can perform properly.

Which Power Plus cam should I choose?

The CR480 suits torque and touring, CR483 is the best all-rounder, CR484 suits stronger performance, and CR485 is better for more aggressive builds.

Can I upgrade from Power Plus to Stump Puller later?

Yes. A.P.E. offers upgrade pathways from Power Plus into larger Stump Puller big bore combinations.

Does a cam kit need dyno tuning?

Yes, dyno tuning is recommended to ensure optimal performance after installing a cam kit.
