Just did a spark plug replacement on my 2014 LX 2.4L i4 engine. It's so simple that it took me 20 minutes to do on my own. Dealership wanted to charge me $399 for it which is crazy.
I used NGK Laser Iridium plugs. Part# 93199. It's roughly $16-$17 a plug but they are one of the best from past experience.
You just need a 10 mm socket and then a 5/8 spark plug socket. Also a socket extender and a socket wrench. It seriously took me 20 minutes to do all four. Very simple to do on your own. Here's a pic of the old plugs I took out and one of the new plugs I put in. 102,000 miles. Some of the gaps on the old plugs were in the 0.037 range when they should be in the 0.044 range. So looks like the factory messed up on the gaps or didn't care. Two of the old plugs had 0.042 gaps while two had 0.037 gaps. The new plugs all had 0.044 gaps which is what they should be.

Also here's a step by step guide on how to do it. Found it interesting.
