Supertech Sodium Filled Inconel Exhaust Valve Set for Honda K20C1, 29mm Head Diameter - HEVI-1060D-HS-8

If you're diving into the world of performance upgrades for your Honda K20C1, you’ve probably heard about the Supertech Sodium Filled Inconel Exhaust Valves. These aren’t just any valves; they’re designed for serious enthusiasts who want to push their engines to the limit. Trust me, I've seen the difference they make firsthand.

So, what’s the deal with these valves? For starters, the head diameter is a solid 29mm, which means they can handle a good amount of airflow without choking your engine. The material is where it gets interesting—these valves are made from Inconel-Nimonic and filled with sodium. This combo not only helps with heat dissipation but also keeps the weight down, allowing for quicker response times. You’ll appreciate that when you’re on the track or just cruising through the canyons.

They come with a single groove design, which might not sound like much, but it plays a crucial role in ensuring a snug fit and reliable performance. The overall length of these valves is 114.7mm, with a stem diameter of 5.47mm, making them a perfect match for your K20C1 setup.

Installation is straightforward, especially if you’ve got a bit of mechanical savvy. Just make sure you’re ready to give your engine the love it deserves. With these valves, you’re not just upgrading; you’re enhancing the entire driving experience. They fit like a glove, and once they're in, you’ll notice the difference in how your engine breathes and performs. If you’re serious about getting the most out of your Honda, these valves are definitely worth considering.
