JBA 97-11 Ford Ranger 4.0L OHC w/Driver Side EGR 1-1/2in Primary Ti Ctd Cat4Ward Header

If you're looking to get more power and better efficiency out of your 1997-2010 Ford Explorer or 2001-2011 Ford Ranger with the 4.0L OHC engine, these JBA Cat4Ward headers are a solid option. They replace the restrictive factory exhaust manifolds with a less restrictive design that helps your engine breathe easier, which can lead to noticeable gains in horsepower and torque, especially in the RPM range you use most often for daily driving and towing.

These headers are built from strong stainless steel tubing, which holds up well to the heat and stress of everyday use. The flanges are a thick 3/8 inch, and the oversized exhaust ports are machined for a flat, leak-free seal against the cylinder head. JBA uses their proprietary Firecone collector design, which is a proven technology for maximizing exhaust scavenging and improving power output. They also include factory-style emission connections, making it easier to hook up your emissions equipment for a cleaner, more compliant exhaust system. The titanium coating on the primary tubes helps manage heat and can contribute to longevity.

Installation includes high-quality hardware to ensure a professional, no-leak setup. These headers are designed to fit directly onto your vehicle, simplifying the installation process. While they are a direct fit, remember that any exhaust modification may affect emissions compliance, so it's always a good idea to check your local regulations.
