The airbox gasket has two pins for locating the gasket holes. The pins also don't match the static box. Must be cropped to allow the gadget to be properly oriented. Mfg error. I checked with support, they insisted it would fit my 4.6L 99 TRITON FOR EXPEDITION XLT engine. The support did not know which gasket set fits the engine. The correct number is FELPRO MS 92121-2. The gasket was exactly the same as the one I removed. Help Desk needs to update its reference number. My engine has an aluminum intake manifold, not plastic. You should also check the VIN, which will give you the correct gasket set.
