Fits select 1992-2000 Honda Civic and Civic del Sol models (1.6L SOHC VTEC).

Ensure your valvetrain remains stable under high-load conditions with BLOX Racing Valve Springs. Engineered specifically for the Honda D-series SOHC VTEC platform, these performance springs are designed to prevent valve float, a common issue when pushing higher RPMs or utilizing aggressive camshaft profiles. By providing increased seat and open pressure over factory components, these springs maintain precise valve timing and protect against potential engine damage.

• Designed for high-performance street and track applications
• Reduces harmonic vibration and prevents valve float at high RPM
• Specifically engineered for 1.6L SOHC VTEC D-series engines
• Direct replacement for worn factory springs
• Manufacturer Part Number: BXPT-20301

Fits 1994-2001 Acura Integra GS-R and Type R, 1999-2000 Honda Civic Si, and 1994-1997 Civic del Sol VTEC.

BLOX Racing Lost Motion Assemblies (LMAs) are engineered to replace the aging factory hydraulic-style units found in B-Series and H-Series VTEC cylinder heads. Over time, original hydraulic LMAs often lose their effectiveness, leading to the notorious "VTEC clatter" or valvetrain noise. These BLOX Racing units utilize a modern spring-type design that provides consistent tension against the high-lift rocker arm when VTEC is disengaged, preventing rocker float and ensuring valvetrain stability at high RPM.

• Eliminates valvetrain noise and ticking common in high-mileage VTEC heads
• Spring-type design offers superior durability over OEM hydraulic pistons
• Ensures proper rocker arm alignment and contact during high-RPM operation
• Critical upgrade for performance camshaft installations and cylinder head rebuilds
• Direct replacement for factory Honda/Acura components
• Manufacturer Part Number: BXPT-11300

Fits 1990-2001 Acura Integra and Honda CR-V (1.8L).

BLOX Racing Titanium (Ti) Valve Retainers are engineered to reduce valvetrain mass and improve high-RPM stability in B-series non-VTEC engines. By replacing the heavier factory steel retainers with lightweight, precision-machined titanium, these components decrease reciprocating weight, allowing for quicker engine response and reducing the risk of valve float during high-performance or racing use.

These retainers are CNC-machined to exacting tolerances to ensure a precise fit and reliable performance under the stress of aggressive cam profiles and increased engine speeds. They are an essential upgrade for B18A, B18B, and B20 DOHC cylinder heads.

• Manufactured from high-grade aerospace titanium
• Reduces valvetrain mass for improved RPM capability
• Helps prevent valve float in high-performance applications
• CNC-machined for precise fitment and durability
• Direct replacement for OEM retainers in B18A/B and B20 engines
• Manufacturer Part Number: BXPT-10403

Fits select 1993-2001 Acura Integra GS-R/Type R, Honda Civic Si, Civic del Sol VTEC, and Prelude (1.6L / 1.8L / 2.2L). This includes B16A, B18C1, B18C5, and H22A DOHC VTEC engines.

BLOX Racing Ti Titanium Valve Retainers are engineered for high-performance valvetrains where weight reduction and high-RPM stability are critical. By replacing heavy factory steel retainers with precision-machined titanium, you significantly reduce reciprocating mass. This modification is essential for preventing valve float and ensuring the valvetrain can keep up with the demands of high-lift camshafts and increased rev limits.

• Manufacturer Part Number: BXPT-10400
• Material: Aerospace-grade Titanium
• Engine Compatibility: B16A, B18C1, B18C5, H22A (DOHC VTEC)
• Designed to handle increased spring pressures and high-lift profiles
• Reduces valvetrain inertia for faster response and improved reliability at high RPM

Fits 1990-2001 Acura Integra and Honda CR-V models equipped with 1.8L or 2.0L DOHC engines (B18A-B / B20).

BLOX Racing valve springs are engineered to provide the increased tension required to maintain valvetrain stability in performance applications. These springs are designed specifically for the B18A/B and B20 non-VTEC cylinder heads, offering a direct replacement for tired factory springs. By increasing seat pressure and open pressure, they help prevent valve float and ensure reliable valve closure at higher RPM ranges, protecting your engine during spirited driving or track use.

• Manufacturer Part Number: BXPT-10302
• Compatible Engines: 1.8L B18A/B and 2.0L B20 DOHC
• Design: Performance-grade wire for consistent spring rates
• Direct fitment for non-VTEC B-series cylinder heads
