Hey guys looking for some advise. I recently purchased a tune up kit and intend on changing the spark plugs in my Boxster this spring. I am also considering changing all the O rings , inner and outer on the plug tubes, is this a good idea? Also, I'm a bit confused, why would oil circulate around the plugs? Either I've read the internet posts wrong or it sounds like these O rings are on the ends of the Beru tube which the plug fits in. any advise or thoughts would be appreciated.

Thanks...
