CTP Valve Inserts –

CTP insert valves are manufactured
with steel alloy comprised of a high
grade of nickel and chromium.
These insert valves are developed to
withstand the high temperatures and
pressures from the engine.
Protect the engine’s cylinder head
from the friction caused by the extreme
temperatures and pressure of your
engine valves with CTP insert valves.
