XC90 TuneUp: Oil, Spark Plugs, Air & Fuel Filters, Trans Fluid Flush

Spark Plugs 1 – The turbo line that goes front to back will need to be removed. What I did was just remove the clamp ring towards the front of the line (because it is easiest to get to), but there is also one at the back. If you can do what I did, loosen the front clamp and pull the plastic hose out of the rubber.
