Description
Set of 16 MWR valve springs for the 2ZZ-GE engines.
The MWR valve springs are a very popular upgrade for the 2ZZ-GE engines.
These springs are 15% stiffer than the standard valve springs for the 2ZZ-GE, without unnecessary friction and wear with a lot of use.
These springs are used worldwide for competition use including endurance races.
The MWR springs work perfectly for street or circuit use up to 9000 rpm and are therefore also an ideal protection against crooked valves during unexpectedly high revs use (accidental incorrect shifting causing the engine to rev too high.
They work with standard camshafts up to 9000 rpm and with aftermarket camshafts up to 8600 rpm.
Made to the highest standards, these springs are a direct replacement for the standard springs and no further modification is required and work perfectly with standard original or the MWR titanium retainers.
