If you're working on a Honda engine and need to replace those worn-out valve stem seals, this Caltric set has exactly what you need. You get four seals that are direct replacements for Honda part number 12209-MN1-671, so you can tackle that valve job with confidence. The dimensions are spot-on: 8.6mm width, 13.5mm length, with a 6.2mm inner diameter and 10.6mm outer diameter - they'll fit right where your old seals came from. Now, a quick word of advice - before you install these, take a second to compare them to the original seals you're removing. Make sure the shape and measurements match up, because getting this right means no more oil burning, better compression, and smoother engine performance. These seals are designed to handle the heat and pressure inside your engine while keeping oil where it belongs and out of the combustion chamber. Whether you're a professional mechanic or a serious DIYer doing your own head work, having the right seals makes all the difference in a successful repair. The quality is solid - they're made to OEM specifications so you know they'll last. No more blue smoke on startup or losing oil between changes! Just make sure you've got the right application and take your time with the installation.
