    I would highly recommend acquiring an 02 sensor socket to remove it. Makes the job a lot easier, IMO. The times I've needed one, I just used AutoZone's rental program. You get all of your money back when you return the tool, so it winds up being free.

    yea, deff use the rental...you give them a deposit, return the tool and get your money back, otherwise you keep it ...i didnt use it and i had to deal with stalling and the ever famous check engine light...until i replaced it of course, the correct way
    **** off with your candy paint jobs and spoilers that are 8x too big , I say never be complete, I say stop being perfect, I say let... lets evolve, let the chips fall where they may.

    i had to use a 22mm wrench to get it off, jacked the car up and cranked as hard as i could until it turned, you dont need any special tools if a skinny white chick can get it off with a wrench, i only used one spark plug anti fouler though because there is not enough room to put the two on there, there was a heat shield or some type of undercover in the way, after unplugging the battery for 30 mins, the light went off and hasnt come on yet (keeps fingers crossed that one was enough)

    Hey, if it works for you, go with it. For myself, it always seems like things go more smoothly, and there's less chance of breaking something expensive, if I use the correct tools for the job.

    well the thread i had for instructions mentioned the crow foot tool for removing spark plugs but napa didnt have any in stock so since i cant get a socket wrench on there i just used a 22mm hand wrench and all went fine, i dont think much could go wrong loosening it with a hand wrench vs. the crow foot tool (or whatever you call it)

    The 02 sensor socket goes on there very solidly and make easy work of it.

    Makes job easy + Nearly zero chance of busting my knuckles when a standard wrench slips off = Worth the trouble to me. YMMV.
