5VZ Swap Performance Header Set Kit

Upgrade your 3.4L 5VZ-FE Tacoma, 4Runner, or custom pickup V6 swap with this premium 5VZ Swap Performance Header Set. Handcrafted from durable stainless steel, ceramic-coated for thermal control, and designed for precise fitment—increase horsepower, torque, and engine bay clearance in one bolt-on package.

These headers replace the restrictive factory manifolds with full-length, equal-length runners that enhance exhaust scavenging. After the merge collector, you’ll have full access for custom exhaust work—these headers aren’t a slip-on replacement—and they do not support EGR systems, making them ideal for clean-slate builds.

Users report noticeable gains in power and throttle response, even in stock setups.

Stock 5VZ manifolds choke flow and hold heat. These headers fix that by delivering:

• Better airflow for improved horsepower and torque
• Lower under-hood temps thanks to ceramic coating
• Room for steepler assemblies and headers that clear the frame
• 6-gauge, ½ inch flanges built for long-lasting reliability
