Installed this on my 2012 F-150 5.0L using a LubeLocker gasket instead of RTV. Installation went smoothly, and so far everything is working great with no leaks.
One helpful note for other buyers: I couldn't find the recommended cover bolt torque specification in the documentation, so I contacted SPELAB support. Their technical team confirmed a specification of 25–30 N·m (approximately 18–22 ft-lbs). I torqued mine to 20 ft-lbs.
It would be helpful if SPELAB included this information in the installation instructions. Otherwise, very happy with the purchase so far!
