Frequently Asked Questions

Will this fit my 2017+ M8 with variable valve timing (VVT)?

No — this valve is for non-VVT M8 models only. VVT-equipped M8s require a different part number.

Is this an oversized valve compared to stock?

Yes — 1.614 inch diameter is oversized for improved flow over the factory intake valve.

What does the White Diamond coating do?

White Diamond coating resists heat cycling and wear, extending valve life and improving durability under high-RPM operation.

Do I need new valve seats when installing this?

Check the condition of your M8 valve seats during installation. If they are pitted or damaged, have them reconditioned before fitting the new valve.
