Developed for our Toyota G16E-GTS GR Yaris / Corolla engine program. These 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 6, these are of standard size.
Note: Check piston to valve clearance to see if it compatible with your pistons.
