Review on Fel Pro VS 50780 Valve Gasket by Daniel Woods

I ordered these for a 2008 Subaru Forester to fix misfires caused by oil leaking from the original gasket in the spark plug cavity. Oil is conductive and if it coats the spark plug it will cause problems and eventually render your car almost inoperable. They fit perfectly and work as expected. No leaks. The spark plug cavity gaskets were slightly narrower than the ones removed, but it's possible the 8 year old gaskets were just permanently crushed. They still fit well. The only limitation is choosing the right ones for your vehicle. I've had several different sites including Fel-Pro claiming that 2 different kits are correct. They didn't offer an option to choose between the two to get the correct ones even when they provided my VIN. I ended up going with the one that offered the most (probably 60/40) and got lucky in the end. Do yourself a favor and order new spark plugs for installation at the same time.
