Skunk2 305-05-9700 Ultra Stage 2 Camshafts for Honda K24Z7 Civic Si/Acura ILX

Vehicle Fitment

• 2012-2015 Honda Civic Si (FG4/FB6, K24Z7, 2.4L DOHC i-VTEC I4, FWD, 6MT)
• 2013-2015 Acura ILX (DE1, K24Z7, 2.4L DOHC i-VTEC I4, FWD, 6MT)

Fitment Notes

• Designed exclusively for the Honda K24Z7 2.4L DOHC engine - does not fit K24Z3, K24A2, K24V7, or other K24 variants
• High-lift performance valve springs are required - OEM valve springs are not compatible with Stage 2 lift levels
• Acura ILX fitment applies to 2.4L 6MT models only - does not fit 2.0L (R20A) or hybrid (LEA) ILX variants
• 2016+ Acura ILX uses the K24V7 engine and is not compatible with this camshaft
• Peak power is shifted approximately 1,500 RPM higher than stock - engine management tuning is strongly recommended

• Optimized lobe profiles developed in-house via advanced CAD simulation and dyno validation
• Delivers 25-50+ HP gains on naturally aspirated engines
• Delivers 75+ HP gains on forced induction applications
• Peak power shifted 1,500 RPM higher than stock for a broader, more aggressive powerband
• High-lift design requires upgraded performance valve springs for safe, reliable operation
• Suitable for both street and strip use on the K24Z7 platform

Product Description

The Skunk2 Ultra Stage 2 Camshaft Set (305-05-9700) is purpose-built for the Honda K24Z7 2.4L DOHC i-VTEC engine found in the 2012-2015 Civic Si and 2013-2015 Acura ILX 2.4L. Engineered as a high-lift, high-duration camshaft, the Stage 2 profile shifts peak power approximately 1,500 RPM higher than stock - unlocking 25-50+ HP on naturally aspirated builds and over 75+ HP on forced induction setups. Each camshaft is machined from forged 8660 alloy steel, induction hardened, and CNC precision ground to exacting tolerances using Skunk2's in-house CAD-developed lobe profiles.

Unlike the Stage 1 drop-in option, the Ultra Stage 2 requires high-lift capable performance valve springs to handle the increased valve lift safely. This makes it best suited for enthusiasts running supporting modifications - upgraded intake, exhaust, fuel system, and engine management tuning - who are ready to extract the full performance potential of the K24Z7. Whether building a high-revving naturally aspirated track weapon or a boosted street car, the Stage 2 delivers a significant and well-rounded power increase across the entire powerband.
