Description
Description
The XFI (Xtreme Fuel Injection) Advantage The Competition Cams 12-367-4 is the most aggressive street-level member of the XFI family. This camshaft is designed for late-model engine swaps or heavily modified EFI systems. Ground with “fast-opening” ramp profiles, it works best with 1.6 ratio rocker arms to create massive “area under the curve,” providing a dramatic increase in mid-to-high range power. You should buy this kit to push your engine to its absolute performance limits.
High-End Power and Aggressive Driving This is built for performance. With an operating range of 2,400–6,400 RPM, it transforms your engine into a high-revving powerhouse. The wide 113-degree lobe separation angle is the secret to its success in fuel-injected vehicles, providing a clean manifold vacuum signal for your sensors while still allowing the engine to breathe at high speeds. This ensures your computer remains synchronized while you enjoy a significant surge in top-end horsepower.
Superior Valvetrain Integrity To handle the high-lift and aggressive ramp speeds of the 280XFI, this kit includes Premium Redline High-Performance Lifters. These hydraulic flat-tappet lifters are manufactured with advanced metallurgy to withstand the extreme mechanical stress of high-output lobes. Precision-machined oiling ports ensure a constant film of lubrication between the cam and lifter, which is essential for a successful break-in and long-term durability.
The “XFI Feel” – Pure Muscle By choosing the 280XFI, you are giving your engine a serious personality shift. At idle, you’ll hear a noticeable, performance chop that signals a high-output build. On the road, you should buy this cam for the way it pulls—starting hard at 2,400 RPM and continuing to climb all the way to 6,400 RPM. It feels snappier and more responsive than traditional cams, making it perfect for those who want a street car with track-ready power.
