IS x50 Spark Plug Replacement?
is there a write-up on how to change the spark plugs for the IS x50? i have an IS250 and have a little over 90,000 miles on it. BTW would you go to the dealer to buy the stock spark plugs or would you buy another brand (and where?) thanks

There's no write up on here about changing the plugs. You can wait till 120k to change the plugs if you want. That's what we're doing. ALso I would definitly recommend using factory plugs. It's not a cut and dry process of changing the plugs on these motors. The passenger side bank requires you to remove the upper portion of the air box, and the ventilation hose. The passenger side will require you to remove the upper intake plenum before you can gain access to the coils.
