I've seen the you tube and links from here, but is a '14 change the same as earlier years sans iridium plugs? Any good advice?
I don't know if the FB has a "Wasted Spark" (Fires every 360 degrees). That might be a reason. Other possible reason is to get folks back to the dealer. I personally would change plugs at that mileage anyway. But then again...I was raised on the copper plugs. :icon_eek:The front plug on the passenger side looks like it might be very difficult to get out. With the 14's I guess we have plenty of time to figure it out. Anyone know why Subaru recommends replacing plugs at 60K miles when everyone else is at 100k?
The FB25 is a "coil-on-plug" engine with a separate coil for each plug. Each plug fires once every 720 degrees.I don't know if the FB has a "Wasted Spark" (Fires every 360 degrees).
Where are you getting your information on when servicing needs done?Did the job... looked like a waste of money.
Yea I actually thought that might be the case but I didn't want to put out more bs. :biggrin:The FB25 is a "coil-on-plug" engine with a separate coil for each plug. Each plug fires once every 720 degrees.
I suspect this coil-on-plug configuration is directly related to the 60K plug change interval for the EJ25 turbo and the FB25 engines. The "old" non-turbo EJ25 engine's "wasted spark" configuration delivered a 30K mile plug change interval.

This along with the fuel filter thread. Want to make sure you are not wasting money...
Here is a good, easy to read, chart showing the maintenance intervals for each item. 2014 Subaru maintenance schedule and new car break-in period
How was it getting the front passenger side plug out? At first glace it looks really tight to get to.Did the job. Not too bad, about two hours of leisurely work. Old plugs looked as good as the new ones, maybe the electrode was a bit more rounded than new, but looked like a waste of money.
I removed the air filter case and etc. on the pass side and the battery and etc. on driver's side. The purchase of a multi-jointed 3/8" drive socket wrench from our friends at Harbor Freight really made the job livable.How was it getting the front passenger side plug out?

Top down was really not as bad as I expected. FYI, the "skid" pan is held on with a few easy to get at screws. I know, because I dropped the socket and had to go after it. Subaru was kind enough to include snap open mini-hatches in the pan, but too small to get the socket. But overall I will agree with those who recommend going through the hood to remove the plugs. As a matter of fact, I'm not sure it can be done any other way.It's been a long time since I did Subaru plugs, but IIRC, they were much easier to get to from underneath. The aero package on the '14 may make that a bigger pain than it used to be.
