Short answer.....yes. It is time consuming and the rear 4 are a little difficult to access but it can be done if you take your time and have any knowledge of cars at all.
FOLLOW THE SPARK PLUG WIRES TO THE BLOCK. AND YOU WILL FIND YOUR PLUGS. A FEW OF THEM ARE HARD TO CHANGE BUT JUST PERSIST AND YOU'LL BE FINE

Hard to start when cold?? Warm?? All the above? How many miles on the vehicle? Fuel filter been changed lately? How many miles are on the spark plugs?
A Toyota Allion has 4 spark plugs. These spark plugs are not hard to replace, and can be found in the engine, under the hood. After 2008 models, they are harder to replace.
It is pretty easy to change spark plugs on most cars. Buy a Haynes manual at an auto parts store; it will walk you though it step-by-step. The gap should be listed on a sticker either by the radiator or the underside of the hood. It is usually possible to by pre-gapped spark plugs, but you should still check them. For the 1.8t engine -> It is not too hard. Just take off the plastic cover, undo the Allen bolts around the square things, pull out the long plastic tube thing and use a spark plug socket. The gap is .028. I had the guy at the auto parts store gap the new spark plugs.
The most common things I have found in my car is the spark plugs, fuel injector and in desperate need of an oil change.
If someone who knows what they're doing changed them, it's hard to guess. If someone incompetent changed them, they may have hooked the wires up in the wrong order.
Some one got lazy and did not change them all. Or chose not too do the hard ones.
Better service you car, go to meganig, the 2-4-6-8 plugs are in front of you when you look the enging but the rest are on the back hard to get them.
Very easy. You have to pull the engine cover off. then pull the coils off and unbolt the plug.
you must remove the plenum on top of the motor to excess the spark plugs it is not hard but time consuming to say the least
The 2.5L engine has 8 plugs and it does only have 4 Cylinders...It has a dual ignition system.The 2 rear spark plugs and wires on the Driver's side are hard to get to...
