This model features an undercut stem in the head area. In addition to reducing the valve weight (which provides benefits in opening rate and RPM limits) the radius of the head is such that is significantly improves air/fuel flow. This model enjoys great success when used with stock heads, as well as modified versions. Fully swirl polished. Chromed stems and Stellite tips. Ideal for tough racing applications of all kinds.
The Black Nitride coating is a surface treatment done to the valve metal that allows a higher resistance to wear along with reducing friction for quicker and higher revs.
Also available in 1mm OVERSIZE for ultimate in flow potential. Extra head machining is required for oversized valves.
Sold as a set of eight valves. Specify intake or exhaust, and standard or 1mm oversized.
Fits all DSM 4G63 engines. That's 1990-1999 Eclipse/Talon/Laser.
