HEAT RESISTANCE & DURABILITY
" INTAKE -Â SUH35 HEAT RESISTANT STEELÂ with SPECIALLY FORMULATED COATING.
-Â The intake valves are made using SUH35 HEAT RESISTANT STEEL which is more commonly used to make exhaust valves. These are then coated with a special formula that further improves the valves' resistance to heat, wear and corrosion.
" EXHAUST -Â INCONEL 751 ALLOY
-Â In order to withstand temperatures of up to around 1000?, the exhaust valves are made using a nickel based heat resistant alloy, INCONEL 751.
