  • Coil Bind: 19.50mm

  • Rate: 10.00 lbs/mm

• Ideal for Aggressive Cams: These springs are a critical component when installing high-lift, long-duration camshafts in your B16 or B18C.

• Direct Fitment: Specifically designed for Honda B16A, B17A, and Acura B18C (GSR/Type R) VTEC engines(set of 16 springs).

Ensure peak performance and uncompromised valvetrain stability in your turbocharged or naturally aspirated race engine. Pair these springs with Supertech Titanium Retainers (sold separately or as a full kit) for maximum weight reduction and the highest RPM ceiling.
