Cometic Head Gasket MLS 100MM .040 - Subaru EJ25 Turbo Models (inc. 2004-2007 STI / 2006-2014 WRX)
Manufacturer Part # C4264-040
The center or shim layer of the gasket is comprised of an uncoated stainless steel layer, which can be varied to accommodate multiple thickness requirements. The MLS gasket is ideal for both aluminum heads to cast iron blocks and aluminum heads to aluminum blocks.
The composition of MLS will also withstand the shearing forces created by aluminum heads on cast iron blocks. No re-torque is necessary. By design the MLS gasket promotes an even torque load across the sealing surface allowing for measurable reduced bore distortion.
One Gasket Included in this item, 2 are required for a full motor build.
