Iridium Plugs in a Subaru

Comments about Denso FXE22HR11 Iridium Long Life Spark Plug:

To all Subaru Impreza owners I would urge you to watch the U-tube on how to change the spark plugs in a 2012 Imprez before you start this job. The key to this is having the correct tools. Space between the engine and body is the issue. You will need the following socket wrench extensions: 1 inch, 3 inch and 6 inch. You will also need a universal to remove the rear drivers side plug. Finally, a 14mm spark plug socket will be very helpfull to get the plugs out, but I used a deep well socket and a magnet.

    Comments about Denso FXE22HR11 Iridium Long Life Spark Plug:

    Perfect fitment, and installed without a hitch. I have the piece of mind knowing I used the OEM spark plugs as replacements, and a qualitypart that should last a long time.

    Piece of advice for you other 07 - 08 350z owners. Don't bother removing the intake manifold. The plugs can be reached by removing you intakes and throttle bodies. Once I had those out of the way, installation was a breeze. Picked up some dielectric grease and anti seize of course, and no issues.

    Comments about Denso FXE22HR11 Iridium Long Life Spark Plug:

    At 86,000 miles, and some change, I decided it was time to replace my plugs...even though they're supposed to last until 110,000 miles. Many forums I'd read stated that they (G35 owners) were replacing their plugs at 60,000 miles, regardless of what the manual stated. As tempting as it was to avoid a 2 hour plug change (the average length of time for an Infiniti G35), I figured about 80-85% of the usable life was gone from my plugs so it was going to happen soon enough.

    The gap for my vehicle's plugs is right at .043\.044. These were gapped at .046\.047 so I had to very gingerly adjust the gap down. Obviously, you can't use pliers as iridium is a very delicate metal. I wound up using the wide plastic handle of a screwdriver to place the grounding prong against and gently apply pressure - worked like a champ.

    With all plugs properly gapped, and replaced, the vehicle's acceleration has improved unbelievably. I thought this car was fast before, but I'm pleasantly surprised at the improvement in performance with just six plugs and two hours of time. Now I'm gauging my mileage to see how much of an improvement, if any, I see.
