284/280 - 11.80mm/11.30mm Valve Lift
The ultimate NA stage 1 performance cams for B16A and B18C. Still maintains good street drivability and mild idle off-VTEC. The 176-B VTEC lobes open up top end power in the 5.5k-9.5k rpm range for track use or spirited driving. Improved mid-range and high rpm power over OEM Type R cams. Must have tunable ECU, intake (such as a whale penis) and exhaust system upgrades. OEM intake manifold can still be used. Requires valve spring upgrade, Kelford Cams recommend KVS18-K. Primary lobe spec: Intake: 242/6.0mm 242/8.4mm | Exhaust: 236/5.8mm 246/7.8mm
