 It's the LS1 engine, I believe. And 23,000 miles on it runs perfect. And it suddenly dawned on me that I still have the original spark plugs in there. And I'm wondering if I need to get those out just from an age perspective. And then the second question I have is if I do replace the spark plugs, do you guys recommend anti-seize or no anti-seize? On an 02, I'm not going to put any anti-seize on them. But, you know, I want to take them out.
