POINT-1 HKS Original Materials
- Exclusive chill camshaft material for HKS is used.
POINT-2 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.
POINT-3 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 flow and/or cam lobe friction.
POINT-4 Stock Valve Timing.
- 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 happen.
POINT-5 Higher Reliability by In-house Design & Production
- HKS controls from the production, inspection, package, and shipment for quality assurance.
- MADE IN JAPAN (HKS In-house Production)
