ScienceofSpeed Engine Intake & Exhaust Valves

ScienceofSpeed offers engine valves manufactured from forged hardened stainless steel in either stock or +1mm sizes. Valves are identical to factory in stem width and overall length and are compatible with factory valve guides, seals, and seats (plus size requires regrind).

These valves feature a hard black nitrite coating (not pictured) which increases material hardness and lubricity for decreased heat build from friction.

Valves are swirl polished and have tapered stems. Plus sizes feature dished base for decreased mass.
