Blox Racing BXPT-20200 Valve Spring - High Compression 33mm Intake Set for Honda B-Series VTEC

BLOX Racing high compression intake valves are precision-forged from EV8 stainless steel and engineered specifically for Honda B-Series DOHC VTEC engines. Each valve undergoes a specialized heat treatment process to increase strength and durability, then receives a black nitride coating that provides superior wear resistance while minimizing power-robbing friction between the valve stem and guide.

Performance Benefits:

• Black nitride coating reduces friction for measurable power gains
• Optimized valve head design increases intake airflow through the cylinder head
• Raises compression by approximately 0.3 points
• Enhanced corrosion and wear protection for extended service life

Technical Specifications:

• Valve Head Diameter: 33.00mm (standard size)
• Valve Stem Diameter: 5.48mm
• Overall Length: 102.5mm
• Material: EV8 Stainless Steel with Black Nitride Coating
• Valve Type: Intake

Compatible Applications:

• 1989-1991 JDM B16A
• 1992-2000 JDM B16A, USDM B16A2/B16A3
