Cylinder Head - Subaru LEGACY 2002 Quick Reference Index

7. Cylinder Head

! The cylinder head is made of aluminium die casting.
! Each combustion chamber in the cylinder head is a compact, pentroof design. The spark plug
is located at the center of the combustion chamber, which contributes to creation of a wide "squish
area" for increased combustion efficiency.
! The two intake and two exhaust valves are arranged on opposite sides for a cross-flow feature.
! The cylinder head gasket is a metallic gasket consisting of three layers of the stainless steel
sheets. It is highly resistant to heat and maintains high level of sealing performance for a long pe-
riod.
