Will this gasket work for both driver and passenger side headers?

This is a single gasket for one bank. If you're replacing both headers, order two — one per side.

Do I need to clean the sealing surface before installation?

Yes. Remove all old gasket material and carbon buildup from both the header and cylinder head with a gasket scraper. Clean surfaces ensure a tight seal and longer gasket life.

What's the return process if the gasket doesn't fit?

Contact our support team with photos of the fit issue. We'll assess the problem and handle exchanges or returns according to our standard policy.
