Fel-Pro Cylinder Head Gasket Set HS 26415 PT-1 for Subaru Forester 2006–2010 — MLS construction, embossed seals

Fel-Pro HS 26415 PT-1 is a multi-layer steel cylinder head gasket set engineered to restore reliable sealing for select Subaru and Saab engines.

This Fel-Pro head gasket set replaces worn or damaged cylinder head seals with a professional-grade solution built for repair environments. It combines multi-layered stainless steel, embossed sealing beads and a proprietary coating so the gasket resists high cylinder pressures, accommodates head lift and seals imperfect or roughened surfaces common after service or wear.

What vehicles and years does this gasket set fit?

This kit is designed for specific Subaru and Saab models from the mid-2000s. Always verify fitment against your vehicle’s exact year, engine and trim—using the seller’s confirmed-fit tool is recommended before ordering.

• Fits Subaru Forester model years 2006–2010
• Also fits 2006 Subaru Baja, 2006–2011 Impreza, 2006–2009 Legacy and Outback
• Compatible with 2006 Saab 9-2X where applicable
• Confirm using year, make, model, engine and trim information

How does the Fel-Pro design handle imperfect sealing surfaces?

The HS 26415 PT-1 uses a combination of surface treatments and layered construction to seal surfaces that aren’t factory-smooth. Its exclusive coating tolerates rougher finish up to 80 Ra while embossed sealing beads concentrate sealing pressure at key leak paths.

• Proprietary coating resists rough sealing finishes
• Embossed beads provide targeted sealing at coolant and oil passages
• Multi-layer stainless steel maintains compressive stress under head lift
• Optimized for typical repair-surface conditions after head work

Why choose a multi-layer steel (MLS) gasket for these Subaru engines?

MLS construction offers a durable sealing platform that copes with thermal cycling and the head movement seen in modern engines. The multiple stainless steel layers flex and retain clamp load better than single-layer materials, helping prevent leaks under higher combustion pressures.

• Multiple stainless steel layers resist permanent deformation
• Accommodates head lift and repeated thermal cycles without losing seal
• Designed to handle higher cylinder pressures safely
• Durability suited for long-term repair reliability

What should I check before installing this Fel-Pro gasket set?

Proper installation and surface preparation are critical for a reliable seal. Inspect and, if necessary, machine the head and block surfaces to remove warpage or heavy corrosion, follow torque sequences and use vehicle-specific service procedures.

• Verify exact vehicle fitment using year, make, model, engine and trim
• Inspect and dress head/block sealing surfaces for flatness and cleanliness
• Follow manufacturer torque specs and sequence when tightening bolts
• Replace related components (head bolts, seals) as recommended

Who is this for: Technicians, DIY mechanics and restorers working on mid-2000s Subaru and compatible Saab engines who need a professional-quality head gasket replacement. This Fel-Pro kit is aimed at repair scenarios where the cylinder head or block may show wear, and where an MLS gasket with targeted sealing features provides the best chance of a leak-free repair.
