Developed for our Toyota G16E-GTS GR Yaris / Corolla engine program. These sodium filled inconel exhaust valves are superior to the standard valve.
Our sodium filled inconel valves offer a significant reduction in valve head temperatures that are required for today's modern day turbocharged engines.
A cooler valve improves the strength and durability of the valve. Not only that, but on average a 10% weight reduction is also achived.
The black nitrided stainless steel intake valves are superior to the standard valve.
The black nitrided treatment allows for a smoother finish and less friction between the stem and guide.
The valve seat is also harder with the nitrided layer making them more suitable for race fuels.
Sold as a set of 12 (6 x exhaust, 6 x intake)
Note: Check piston to valve clearance to see if it compatible with your pistons.
