7.3 Powerstroke Ford OE Oil Rail End Plug

Simple and straight forward install. Easiest with the turbo out of the way. Make sure to order 2 and do both the rears as those are the common fail points. Loctite 277 is a necessity on these. If you have a 4 inch down pipe its a little tight, loosen the mounting clamp for the down pipe at the connection where it meets the exhaust and it should give you enough wiggle room to get the passenger side plugs out. After replacing make sure to pull the top front plug and sensor on each of the front oil rails and fill with oil so you don't get an air bubble under the sensor and a rough idle.

Was cheaper here then thru my ford dealer!
