I recently installed an Everbuilt gasket in my 2003 Powerstroke and I am blown away by the difference it's made. My engine runs smoother and I've noticed an increase IN power .The gasket is automotive-grade and built to last. The only downside is the slightly higher price compared to other gaskets on the market, but the quality is well worth it. Overall, I highly recommend this gasket to anyone looking to enhance their engine's performance..
