FEATURES:
HKS Original Materials:
– Chill camshaft material exclusively for HKS is used.

Must be used with the special Valve Spring:
– Duration and valve lift were both designed larger than a stock.
– The valve spring included in this set must be used with this high lift camshaft.

Optimized Camshaft Profile:
– Lift volume was decided after the cylinder head measurement and flow test.
– Duration was decided to be well-balanced with a selected lift volume on the power curve at all range.
– The camshaft profile was optimized to clear points of the valve jump and/or cam nose friction.

Same Valve Timing as a Stock:
– The knock pin phase to position the cam pulley is the same as a stock, so the valve timing can be same as a stock.
– The cam sensor trigger position is the same as a stock so the malfunction of the stock ECU won’t be led.

Higher Reliability by In-house Design & Production:
– HKS controls from the production, inspection and package.
