FEL-PRO® PERMATORQUE® MULTI-LAYER STEEL HEAD GASKETS SOLVE SEALING ISSUES ON 2.5L ‘BOXER’ ENGINES:

Doing another HG replacement on a 2.5L engine? Thousands of Subaru 2.5L SOHC “Boxer” engines may be susceptible to sealing problems related to the composite-style original equipment head gaskets. Today’s lightweight engine designs present tough challenges for head gaskets. Increased casting motion between the head and block surfaces on these engines can quickly cause crushing and scrubbing damage to the composite gaskets. As a world leader in MLS gasket technology, Federal-Mogul Motorparts has introduced two next-generation Fel-Pro® PermaTorque® MLS head gaskets that eliminate sealing concerns on the full range of Subaru 2.5L SOHC and DOHC engines dating back to the 1996 model year.

Fel-Pro Solution:

The new Fel-Pro PermaTorque MLS head gaskets combine Federal-Mogul’s proven-aftermarket MLS technologies with a next-generation stopper-layer design developed and validated in partnership with leading pe rformance engine builders.

The new Fel-Pro LaserWeld™ stopper layer provides a precisely engineered compression limiter that eliminates combustion sealing concerns on even the most challenging turbocharged applications. LaserWeld technology is now a standard feature of the PermaTorque MLS head gaskets for these Subaru engines. And the corresponding Fel-Pro “HS” sets (head sets) include all of the gaskets needed to complete the job.
