Honda Civic Integra B16B B18C Type R Lightened Intake Valves & Dual Valve Springs
This is a sale for 8 unit sets of brand new genuine Honda Civic Integra B16B B18C Type R Lightened Intake Valves & Dual Valve Springs from Honda Motors, Japan.
B16B B18C Type R Intake Valves are same diameter as regular B-series valves but have distinct advantages in being 12% lighter in mass, with noticeably thinner valve stem from 5.5mm to 4.6mm, hence larger cone area and an improved contour for better air flow. Type R lightened intake valves are made so precise that their static balance differential is basically 0.0. Type R intake dual valve springs are specially made to work with Type R lightened intake valves for higher lift and rpm specifications. They are non-cylindrical, flat springs with increased rebounding power while their spring height are still near-stock. This will help to prevent valve-related problems past 8000 rpm such as surging, jumping, bouncing etc.
Fitment also includes B16A, B17A, B18C GSR. Excellent when installed with Type R or performance camshafts.
