Magnus Mclaren M838 and 840 Stainless Super Alloy Valves

Description

Upgraded valves for the McLaren 720S M840T engine and its wider V8 family, with stainless steel on the intake side and high-temperature Inconel on the exhaust. Unlike the sodium-filled factory valves, which can shear the head off the stem in a valvetrain collision and destroy the engine, the Magnus valves keep the head attached so a collision results only in a bent valve rather than a ruined piston or combustion chamber.

Features

• Stainless intake and Inconel exhaust valves
• High-strength construction for high-RPM operation
• Improved durability under high boost and elevated exhaust temperatures
• Set of 32: 16 intake, 16 exhaust (no springs or retainers)
• Pairs with the Magnus high-pressure valve springs for a complete valvetrain upgrade

Applications: McLaren 720S, 720S Spider and all M838/M840 V8 engines.

Professional installation recommended.
