I read the thread title: "Lesson learned?" and a few small things popped into my mind. They are small, insignificant, but may save you from going through the same thing I did. Life's Lessons, so to speak. 1. DO NOT buy a billet aluminum oil cap. Or any other metal oil cap for that matter. It will burn the piss out of your hands if you have to add oil while the engine is warm. Stupid invention. Little bit of bling. Negative functionality. 2. DO NOT install a "Type R" shift knob. I even purchased mine from an acura dealership so I knew I would be getting the real deal. Metal shift knobs SUCK. If it is more than 95 degrees outside, your shift knob will heat to exactly one billion degrees. It sucks to shift with a scalding hot knob. 3. Tabasco hot sauce is aged in barrels for 3 years before it is put in that tiny bottle and sold at wal-mart. That one changed my life. 4. Magnetic oil plugs are the real deal. They really catch debris that is floating around in the oil. Thats all for now.
