Must Have Jaguar XF Upgrades
Performance Upgrades: Power, Sound and Thrills
For many Jaguar enthusiasts, the journey begins with performance. These upgrades are designed to increase horsepower, sharpen throttle response and they are in the form of Jaguar XF tuning and performance parts.
Jaguar XF ECU Remapping: Performance
When we take a look at must have Jaguar XF upgrades, the single most effective performance upgrade for your Jaguar XF is an ECU (Engine Control Unit) remap. By carefully recalibrating the engine’s software, we can safely unlock significant gains in both horsepower and torque. A professional remap optimises fuel-to-air ratios, ignition timing and on supercharged models, boosts pressure. The result is a car that feels more alive, with sharper acceleration and a much stronger pull through the gears. For diesel models, the increase in torque is particularly transformative, making overtaking effortless.
Supercharger Pulley Upgrade: Response
For owners of the 3.0 V6 and 5.0 V8 supercharged petrol engines, a supercharger pulley upgrade is a game-changing modification. By fitting a smaller pulley, the supercharger spins faster, generating more boost at lower engine speeds. This provides an instant and dramatic improvement in throttle response and low-end torque, giving the car a powerful surge of acceleration from the moment you touch the pedal. When paired with an ECU remap to manage the increased boost, this upgrade delivers incredible and reliable power gains.
Performance Exhaust Systems & 200 Cell Catalysts: Sound
The factory exhaust on the Jaguar XF often restrains the impressive sound of its V6 or V8 engine, depending on the model you have. A performance XF exhaust system rectifies this, especially when you upgrade to our exclusive 200 cell high-performance catalytic converters.
Unlike standard 600-cell factory units which restrict gas flow, our ‘E’ certified, large-bore racing cats reduce backpressure substantially. These give a rating to over 675bhp and are proven to deliver a 22-25 bhp mid-range increase. This is what makes them a vital upgrade for tuned engines and while the power gains on their own are impressive, the sound is also transformed. We have options ranging from cat-back systems to switchable valvetronic exhaust systems that allow you to toggle between a refined tone or a noticeable roar.
Handling and Control: Capabilities
Increasing your XF’s power is only half the story. To truly exploit its performance potential, enhancing its handling and braking capabilities is essential. Here’s a brake down of some of the must have Jaguar XF upgrades.
Suspension Upgrades: Agility
Improving your car’s suspension sharpens its handling and gives it a more aggressive appearance. Lowering springs are a popular choice, as they reduce the car’s centre of gravity, which in turn minimises body roll during cornering and improves steering response. For the ultimate in handling precision, fully adjustable coilovers allow you to fine-tune both the ride height and damping settings to perfectly suit your driving style. These upgrades create a car that feels more planted, agile and responsive.
Brake Upgrades: Responsive
More power demands better stopping power. Upgrading your Jaguar’s brakes is a crucial step for both safety and driver confidence. Braided steel brake lines provide a firmer and more consistent pedal feel by eliminating the expansion common with standard rubber hoses. Performance brake pads offer superior bite and are more resistant to brake fade during spirited driving. Together, these must have Jaguar XF upgrades ensure you have the stopping power you need to control your car’s newfound performance.
