🚗 Engine Compatibility
Nissan
- KA24DE 2.4L DOHC
(240SX, Altima, Frontier—the engine that gets turbo’d whether it likes it or not.)
💡 Why Upgrade Your Valve Springs?
Stock springs are fine… until:
- You increase RPM
- Install performance cams
- Add boost
Then you risk:
- Valve float
- Loss of power at high RPM
- Catastrophic engine damage
Upgrading to a dual spring setup gives you:
- Stable valvetrain operation
- Higher RPM capability
- Improved cam performance
- Peace of mind when pushing the engine

⚙️ Installation Notes
- Requires cylinder head disassembly
- Professional installation recommended
- Must be properly matched with camshaft specs
🏁 Bottom Line
If you’re building a KA24DE for performance, upgraded valve springs aren’t optional—they’re protection.
The BC0210 spring, titanium retainer, and seat kit keeps your valvetrain under control when the RPM climbs and the boost hits.
Because bent valves are not a personality trait.
