258° ‘EZ’ power cams to suit near stock naturally aspirated engines. Great for street cars, or jet boats where an increase in low to mid-range power is important. Suits engines with bolt-on intake and exhaust upgrades. Maintains full use of VVT-i. Designed to drop-in on OEM valve springs. These cams also suit mildly turbocharged or supercharged engines wanting a step up from the factory cams, but still maintaining good street drivability. For high milage engines Kelford Cams recommend KVS263 valve spring kit.
