Brand: Tomei
Product: Oversized Valves - PS13 S14 S15
Part Num: 163401

FEATURES:
1mm OVERSIZED WAIST SHAPE:
- 1mm oversized valves were designed for increased flow efficiency on both the intake and exhaust side. The stem has a thinner design for maximizing air flow rate within the port with the reduced air flow resistance. This design with the materials used also allowed for a lighter product as well.

PRECISION DESIGN:
- To maximize the potential of the valves purpose each factor was addressed during the design process from the surface of the valve head (umbrella section) & the Valve Seat, from Stem to Cotter are all optimized with precision for optimum operating & sealing capabilities when needed most during extreme conditions.

SURFACE TREATMENT (INTAKE SIDE ONLY):
- Improved Wear Rate
- Improved Fatigue Rate
- Improved heat resistance
- Improved corrosion resistance

HIGH HEAT RESISTANCE:
IN: SUH35 MATERIAL:
- The SUH35 material which is known for it's high heat resistance properties are usually used for the exhaust side. We chose to use it for the Intake side to suit the the demands of today's users for big power applications and for increased life.

EX: INCONEL 751 MATERIAL:
- Since the exhaust side can experience extreme exhaust gas temperatures of 1, 000 degrees C (1, 832 degrees F) during high power use the Inconel 751 material was no doubt the best option to choose to suit serious needs when every detail counts.
