Brian Crower bc3303-INC Toyota 2JZ Inconel Exhaust Valves 30mm +1mm

The Brian Crower BC3303-INC Inconel exhaust valves are engineered for high boost, high horsepower applications, making them ideal for serious performance builds on Toyota 2JZ-GTE and Lexus 2JZ-GE engines. This set includes 12 premium exhaust valves featuring a 30mm head diameter with a 5.97mm stem diameter and 99.1mm overall length.

Premium Construction:

• One-piece design with friction welded Stellite tip for optimal performance
• Premium grade, heat resistant Inconel material ensures reliability in high boost and high RPM applications
• Undercut stem above the head reduces overall weight for extended RPM potential
• Fully machined with swirl polished finish under the head
• Dished valve design

The undercut stem design significantly improves air/fuel flow in and out of the combustion chamber, enhancing engine breathing and power output. The +1mm oversized head diameter (30mm vs. stock 29mm) provides increased flow potential for forced induction applications. Inconel's superior heat resistance makes these valves the top choice for turbocharged and supercharged builds running elevated boost levels.

Applications: Toyota 2JZ-GTE (Supra Turbo) and Lexus 2JZ-GE (IS300, GS300) engines.
