Straight forward, to the point, clearly explains the job. Well done. Just ordered my plugs from Rockauto.
Thanks! ordered new plugs today and will get this done when they arrive.
Thank you so much for this video. Help me a lot!!!
Ditto on your excellent video time management and explaining everything, mostly as you could. I was an old school (1970-1985 era) mechanic...here's two extra/optional? tips. 1) After removing coil, if you can, give a quick shot of compressed air (or blow hard/fast thru a 3/8" hose) around each plug before removing...to blow out (remove) possible crap/dirt which CAN be a very? bad thing. Less important tip, but may expose more oil in this case. 2) For ease of INSTALLING ( insert+start new plug threads) on any car withOUT using the plug-sized socket to hold it at first: (the hard part: FINDING such an old naked boot,, then) shove an old rubber plug-wire-boot (strip off an old-style single plug wire == old plug boot). That has/gives enough friction for your thumb+finger to best start the plug threads, for a turn or so, then pull the boot off and use the socket on an already-threaded plug. BACK TO THIS PROJECT: Horiz space is atill tight down in coil-land, had to use various tricks to fit tools eg short-flex-10mm socket and just-right extensions for plug/14mm socket. I just got into its-time-to-change-orig-plugs on my GF's 2015 Impreza 2.0 no turbo, 130k mi which runs ok, at first I couldn't even FIND coils,wires,etc..., so now I know how to expose them. The extras on this era (2015-ish) are different enough from my old 1999 Forester which I managed to do head gaskets on! BACK TO THIS PROJ again: Bad discovery: Oil on all 4 in the plug tubes., but just a little (big tiny :) blast of oil when I blew air into plug hole. I wasn't ready to R+R cam-covers (valve covers) and oil seals that day. Hoping the re-installed-with-orig-oilseals doesn't start dripping now that I've swapped plugs. It's always something to fret.. thx for listening, be prepared.

More unknown/invisible-concerns may become exposed by removing coils: My first comment above was made before I dove into this well-running 2015 Impreza 2.0L non turbo (bought new by my GF thus we know it never overheated and never leaked anything like oil,antifreeze) and never burned or lost any oil, changed every 6k or so...now at 135,000 miles. For preventive reasons, I felt it was time to replace spark plugs, so with no known problems, spark plugs were the only new parts I had today. To my surprise, all four plugs+boots (they live inside an insert/tube within the valve-cover aka cam-cover) and the coils' boots were ~equally wet with some oil. Maybe a teaspoon or so in total, used a few feet of paper towel. I blew each exposed plug+hole with 100psi of air, so a small mist of oil came flying out. (No dirt like I warned in my prior comment, this is a sealed tube!) So obviously (if perfection was a goal for today) I SHOULD have ordered cam-cover-gaskets and oil seals, but instead I went ahead with just new plugs...no visible seals looked bad enough to believe this would be a mistake, even though every time you touch something like the outer seals, it could change.... To do that job right, see youtube MrSubaru1387 "Project 2015 Outback: Spark Plugs & Cam Cover Gasket Replacement" 33min video. In my case, I just wiped off all the oil I could with a curled-up paper towel corner, even halfway-in-drying-out each coil boot hole which is normally covering/sealing the plug. (BTW, I found no reason to detach the connector/wire from each coil, which looks a bit challenging. Since the boots are flexible I was able to just angle-and-push/pull them aside, then remove spark plug). After cleaning the tube+boot, and being extra careful watching and pushing the coil's outer boot seal back nice and flat with the just-one bolt tightening each coil down, I got it all back together and it ran great as usual and after a short test drive, I see no oil leaks, so hopefully the continued leak within the cam-covers...leaking into the should-be-dry plug tubes at hopefully slow-leak-rate...will be no problem (she lives 2 hrs from me, so I'll see in a month). Thanks again, best of luck.
thank you for the video. garage quoted me 370 plus tax. I can't afford that also considering decent plugs are ranging from 15-30 each at local store. I think I'll use this video and take my chances to do it myself.
Lucky you. They wanted $800 from me
Appreciate you!

Just dielectric grease from any parts store

@@YOUCANIC Thanks for the quick response. It's a 2015 Impreza Sport. I'll check out your website.
2015 2.0L non turbo owners manual says use NGK SILZKAR7B11 ...without showing plug gap in Specifications. Buy the real deal: NGK set of 4 == qty 4 Laser Iridium Premium (stock#) 93482 and when you get those, each plug box will say both: 93482 + SILZKAR7B11. They come gapped at around .040 so you should NOT have to adjust gap.
@@dougmildram3032 Thanks. I did get the Iridium's. Car sounds great.
