Hi, Im thinking of doing the spark plugs on my 09 with 102,000 miles on it. I’m not the original owner so I have no idea if they’ve been changed or not. Now I’m familiar with the infamous 3v spark plugs breaking in half, but I have heard that they updated the design after 2008, so I’m wondering if I have the better one piece plugs or not. Any info would be appreciated, thank you.
