P304 code on 2001 Sonata

The dealer says this is due to two bad spark plugs and wires which will cost $450 to fix. How difficult are these plugs to replace?

Thanx Larry

If it's a v6, the rear bank requires removing the plenum. If it's a four cylinder, it's very easy.

The misfire problem can be solved by changing spark plugs and wires. You may buy the parts and DIY to save money.
