Floyd9t8 Posted September 7, 2014 Share Posted September 7, 2014 How easy/complicated is it to change the spark plugs on my Subaru Impreza GX Sport AWD? A garage has quoted me £120 (including the sparks @ £8 each). Is that a good deal? Quote Link to comment Share on other sites More sharing options...
Jay762 Posted September 7, 2014 Share Posted September 7, 2014 seems a little high that, it can be a bit fiddly and we have had members wind the socket out into the side of the wheel well swear profusely and have to wind them back in. I dont know how good with a spanner you are but it is a straight forward job Quote Link to comment Share on other sites More sharing options...
stants Posted September 7, 2014 Share Posted September 7, 2014 I'd agree woth jay there, what's that three hours labour ? Removing the airbox on the offside and the washer bottle on the nearside gives you a lot better access. Small drive extension on your socket should give you enough length to reach :-D Quote Link to comment Share on other sites More sharing options...
Gambit Posted September 8, 2014 Share Posted September 8, 2014 A real pain in the !Removed! to do but if you're confident enough to do them yourself I'd save the money but that cost does seem a lot of money for spark plugs to be changed. Is that a mainstealers ? Quote Link to comment Share on other sites More sharing options...
Floyd9t8 Posted September 8, 2014 Author Share Posted September 8, 2014 Gambit.... No that was a small garage in Fareham, Hampshire called BVS Mechanics. Seemingly rip off merchants because i got a new quote today from Collisons (big family run garage) for £59.00 all in. 1 Quote Link to comment Share on other sites More sharing options...
Gambit Posted September 8, 2014 Share Posted September 8, 2014 Thats sounds more like a better price :) Quote Link to comment Share on other sites More sharing options...
ChrisD Posted December 26, 2014 Share Posted December 26, 2014 May be different but there is a video on YouTube that shows you, seems okay to do. Remove air filter box and washbox, pick up a spark plug socket for 4 quid of eBay, seems like it's unplug unscrew old, screw in new ones and plug back the wires. That reminds me is there an order to do this or does it only matter on the cap for this? Quote Link to comment Share on other sites More sharing options...
Gambit Posted December 26, 2014 Share Posted December 26, 2014 No order to go by but I'll say it again, they're a real pain in the !Removed! to change I hate doing them. I know Martin and a few others on here who are pretty good with the engines lift the engine to change. The Back passenger side is by far the worst one, I've thrown some tools around with some profanities just because of that last one :( Quote Link to comment Share on other sites More sharing options...
Andy Hayes Posted December 26, 2014 Share Posted December 26, 2014 i found it easier with the socket a small extension and a large one so u can break it down rather than tryin get a full bar in and around didn't take that ling either.

Andy Hayes Posted December 26, 2014 Share Posted December 26, 2014 i would get some better plugs also rather than standard, i got iridium ones and did make a difference, Quote Link to comment Share on other sites More sharing options...
tom_gr7 Posted December 26, 2014 Share Posted December 26, 2014 I'd ask the garage (whichever you plan to use) how they are going to replace them and check that they are experienced with Subaru's. As some garages don't have a clue about Subaru engines. Before I got my legacy, the previous owner had it serviced and to change the plugs, they disconnected the whole engine and dropped it out of the bottom of the engine bay. The garage didn't put the engine back in straight and left the steering column hanging in the engine bay. Quote Link to comment Share on other sites More sharing options...
ChrisD Posted December 26, 2014 Share Posted December 26, 2014 So whats the difficult part? The video I saw made it look okay? Quote Link to comment Share on other sites More sharing options...

Scooby Pete Posted December 26, 2014 Share Posted December 26, 2014 It's not difficult, just very cramped and getting acces with tools is what makes it hard. I have managed to do it before on my classic. It's getting the ratchet in between the heads and the wheel arch that makes it hard. Also you have to be careful when unplugging and reconnecting the coil packs, as they can get damaged if they are wonky and you try to force them. If you have the ratchet ring type spanner it should be easier as its a lot thinner than a traditional ratchet. Quote Link to comment Share on other sites More sharing options...
Rick 2014 Posted December 26, 2014 Share Posted December 26, 2014 An easy job just need the right tools for the job ie small extentions/decent ratchet and patients Quote Link to comment Share on other sites More sharing options...
Gambit Posted December 26, 2014 Share Posted December 26, 2014 I still hate them but I do suffer with short patience :) I'd recommend you having ago and agree better plugs is better than standard. And as Pete said be very careful with the coil packs. I'm pretty sure you will soon learn to hate them too :D Quote Link to comment Share on other sites More sharing options...
Nevell Posted December 27, 2014 Share Posted December 27, 2014 It is easy just need a few different extension pieces which any half decent tool box should have ,done myn twice now :-) Quote Link to comment Share on other sites More sharing options...
andrewturner150 Posted January 20, 2015 Share Posted January 20, 2015 what advantages are there to iridium spark plugs? Quote Link to comment Share on other sites More sharing options...
quit Posted January 20, 2015 Share Posted January 20, 2015 Tuned engines benefit from the PFR7B plug as they are a cooler ignition, The standard 6frb is ok if your not planning on much tuning (and about 15 quid cheaper!) Quote Link to comment Share on other sites More sharing options...
andrewturner150 Posted January 20, 2015 Share Posted January 20, 2015 right. i'll need a set of those soon. Quote Link to comment Share on other sites More sharing options...
