    Lightbulb Spark Plug Installation Labor

    Is it really necessary to replace the spark plugs at 30k miles on my 2009 2.5i? I have heard that most cars come equipped with platinum plugs from factory, which don't require servicing until 100k miles. Is the maintenance booklet a snake oil tactic to squeeze more money out of the customer?


    I actually went to a mechanic today to inquire about cost of replacement, the receptionist stepped away to ask the mechanic. She comes back and says $60. Is this price too good to be true? I thought the cost would be a lot more since the plugs are in an awkward spot

    $Free.99 + parts if you do it yourself which isn't that daunting of a task. As for mechanic prices though, that's a steal.

    Is a 30k mile spark plug change a must, or can they really go to 100k miles?

    It's better to have them done when it calls for it, if not you can start to lose gas mileage, and your power will drop a little if they get too bad. 100k seems a little long to be running on the same plugs to me...

    Why are you doing this at all... don't you have a maintenance plan?

    The only Subarus that come from the factory with platinum plugs are the Boxer Turbo's and the H6's ..which require replacement at 60k...at least that is how it was for years..things could have changed in 09...

    Personally, even if they were 60k plugs i would replace them sooner than that especially for the first change. And as for cost, i'd recommend doing it yourself. Its a pain and you'll get pissed off but its nice to know in the end you can do the basic maintenance on your own car. I'd suggest replacing them at the recommended time then put in nice iridium plugs and replace those every 30-40k. But that comes from the guy who changes my oil with full synthetic at right around 2500 miles

    Since you just have a N/A Subie...plug change is 10X easier than on a turbo...Thankfully on all of the newer models they also give you a little more room between the valve cover and the "frame" rail..

    actually its very easy to do it yourself, somewhere in theses pages you go to (how to) and there they show you how to do it with photos and explain everything. it helped me a lot.
