FelPro Engine Gasket Kit 3.7 Liter DOHC 2011-2014 Mustang V6

The full gasket kit has just about every gasket needed to rebuild the engine or even go into performance territory. The firing rings in Felpro gaskets are designed to exceed the OEM specs.

Fel-Pro^® holds gasket tooling to a tolerance of just 5 microns – but just how precise is that? A micron is one-millionth of a meter. 5 microns is equal to .005mm or about 0.00020”.

The naked eye can see objects that are about 40 microns or larger.
To put that into perspective:

6-8 microns – Average diameter of a red blood cell
17-181 microns – Average width of a human hair
300-350 microns – Average length of the side of a grain of table salt

This extremely tight tolerance ensures every Fel-Pro gasket seals dependably, just like the one before and after it!
