by

The XJ 4.0 Jeep is known for its ruggedness and capability, but what if you could enhance its performance even further? Installing performance headers is one of the most effective ways to increase horsepower and torque. In this article, we will explore the benefits of installing Borla headers on your XJ 4.0, focusing on the impressive gains of 12-20 horsepower for around $700.

Understanding Performance Headers

Performance headers are designed to improve the exhaust flow from your engine, allowing it to breathe more easily. This leads to better combustion and increased power output. The stock exhaust manifold can restrict flow, which is where performance headers shine.

What are Borla Headers?

Borla headers are high-performance exhaust headers made from high-quality materials. They are engineered to provide superior performance while maintaining a sleek design. Borla is a reputable brand in the aftermarket automotive industry, known for its durability and performance enhancements.
