About this part

Product Details

If you're rebuilding the top end of your 1991-1996 or 1999-2002 Infiniti G20, or a compatible Nissan like the 200SX, NX, or Sentra, you'll want to pay close attention to your exhaust valves. These Manley Race Master exhaust valves are designed to handle the heat and stress that come with performance engine work, especially if you're running alcohol fuels.

Manley builds these valves from a high-quality stainless steel, specifically an XH-426 alloy for the exhaust side, which is known for its durability under high temperatures. They've also added chrome stems and hard tips to resist wear, ensuring they hold up over time. The under-head area is swirl-polished to help smooth airflow, and the combustion face is fully machined for better efficiency. These are the straight-stem Race Master style, which is a solid choice for many performance applications, particularly those using alcohol fuels where they are recommended.

This set includes eight valves, enough for a full engine rebuild on your 2.0L DOHC 16V engine. When you're putting an engine back together for serious use, using well-built components like these Manley valves makes a noticeable difference in reliability and performance.
