What is the best way or how to change spark plugs on a subaru svx?

Nothing too tricky to doing plugs, getting to them is the toughest part. Let the motor cool first, don't even try when its hot. Clean the area around them, a little compressed air works great, Go one at a time, grab the plug boot nice and low, give it a twist to break it loose, then pull and twist. Spin out the plug, put a little anti-sieze on the new one and torque to about 12 - 15 lb-ft. Push the wire back on so it snaps.
