How often do you change your 07 2WD T4R’s spark plugs or 4th generation’s

What makes the un-clipping plug wires from the coil packs hard, quoted above? This was not a problem with my Camry experiences (but tight). jow

The passenger side isn't a problem once you move the airbox out of the way. When you get the driver side bank, you'll see what I mean. The wires clip in pretty snug to the coil packs, but the limited amount of room under the intake manifold is what makes it difficult, unless you have small hands.
