This camshaft is great for a mildly upgraded Naturally Aspirated 4AGE 20V engine with basic upgrades to the intake and exhaust. It has a 264°/264° profile and is perfect for street driving while providing a good increase in mid-range power compared to the original camshafts. The VVT on the intake is still retained, making it suitable for daily use.
We do recommend upgrading to the KVS51-B valve springs from Kelford Cams for optimal performance.
