Do I need new bolts when I install this gasket?

Reuse your factory header bolts and studs if they're in good condition. If you notice stripped threads or corrosion, source matching replacements before assembly.

Should I clean the header and manifold surfaces before installing this?

Yes. Scrape off old gasket material and wipe both mating surfaces clean with a dry rag. A clean seal surface prevents leaks under load.

Will this work on a turbocharged 2.0L engine?

No. This gasket is rated for non-turbo applications only. Turbo engines run hotter exhaust temps and require a different gasket spec—verify your engine before ordering.
