09' Impreza Spark Plugs Install w/Pics
Hello guys, I am new and first Subaru 09' Impreza owner.
I need to change the plugs (32K miles in it now) I looked everywhere and no luck, any one have a pics on where there are located? I already got it from the stealership the other day and I am off for the next days. thanks in advance, Isilveboy Edited for other members to see a how to. Pics are in post #13 So since I couldn't find info anywhere on info or pics, I took the plunge. Let me know if you have any questions regarding the install. The old spark removal was the hardest thing to do, so make sure you got the tools. Next project, tranny and diff oil change. Cheers

Got Them Change
Got them, changed them. Took me 1 1/4 hours.
The cold packs are not hold down by a screw 10mm I believe, instead, they are hold by pressure. You gotta make sure they are all the way in when you put it back. They are along side the engine. On the left side I had to removed the air filter box. I took some pics, ASA I get a change I will upload them. Also took pics of the old ones, look a little burn(you'll see in the pics. Later |

PleiadesSTi, Look on the valve covers for 2 grey 'boxes' (per side) held on by a screw. You take that bolt out and the coil pops off and the plug is down that hole. |

The time it takes to change the plugs depending on experience and level of experience:
- Knows Subarus in and out, and done many engine rebuilds - 20 minutes - Knows Subarus but never changed plugs before - 45-60 minutes total with 15 minutes trying to get #3 and #4 coilpacks over the plug (hint, start it rotated 180*, slide it in and rotate it back 180*.) - New to subarus but experience changing plugs on other makes/models - 1 hour 30 minutes - with 20 minutes fumbling with the coilpack, and another 5 minutes when you forgot to reattach the front 02 wire bracket to coil #3. - New to subarus and never changed the plugs in anything - 4-6 hours. With 2 hours removing and installing extra items that don't need to be touched - ie the battery, the wiring harness brackets, electrical lines and hoses etc... Another hour trying to get the airbox lid back on because you decided to get an K&N panel filter and "do it" at the same time (and still end up missing a tap or breaking a tab) - And many hours fumbling with the other items mentioned above. Oh, likely the newb will not use a torque wrench and over tighten the plugs resulting in cracks from the plug threads to the valve seats. (not giving torque values as they differ depending on if you use anti-sieze or not, or if they are new plugs etc...) The Newb will also likely unplug each coil pack and then forget that the black connector goes on 3 and 4 with the white connector on 1 and 2. They will ultimately search and read this post. Aside - I'm glad you were able to change your plugs on your 09. Hopefully you had more than 2 inches of clearance on each fender when you changed your plugs unlike the rest of us with 02-07. |

And yes I got the 2.5i. I also installed a mirror with a compass, windows tint. In progress is a Viper alarm/remote start, stock Roof racks, Yakima Fairing, splash guards, rear spoiler and maybe do something with the suspension. What can I say, I got the fever. Too bad is the wife's ride |

The non turbo 2.5L does not have direct ignition. So it is just standard high tension wires that snap/pop onto the plug. On the WRX/STI, it is direct ignition so a coil sits on top of every plug and the wire going to the coil is a thin, pansy piece of wire since it is not a high voltage wire. On the DI 2.5L turbos, the coil pack is held on by a bolt. On the N/A 2.5L there is none. |

I've got a 2008 OBS, normally aspirated stock 2.5L (EJ253) and it's time for the 30k plug change. Must be the same set-up as Isilverboy's. I thought I'd go with stock NGK FR5AP-11, like the manual recommends.

All plugs looked great, but one on each side of the engine looked a little grayer. Nothing drastic, but I don't know why that would be. Anyway, thanks for starting a good thread with good pic's. --Pete |
