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.
