SneedSpeed B48 Super Duty Head Gasket — .7mm OEM Thickness Upgrade
Stock thickness. Not stock performance.
The SneedSpeed Super Duty Head Gasket for B48 engines is built at .7mm OEM thickness for MINI and BMW B48 platforms that are making more horsepower than factory ever planned for.
You don’t change compression on a B48 to make power.
You make sure it stays sealed when the power goes up.
That’s what this gasket is built to do.
