About ford focus rear diffuser

Types of Ford Focus Rear Diffuser

A Ford Focus rear diffuser is an accessory fitted to the rear end of a vehicle. It is designed to improve aerodynamics by reducing drag. Car enthusiasts also fit the diffuser to the vehicle to enhance its appearance. The diffuser is available in different designs to suit various preferences. Here are some common types:

  • 1. Carbon Fiber Rear Diffuser

    Carbon fiber rear diffusers are popular among vehicle owners who prioritize performance. They are lightweight, which makes them improve a car's speed and handling. The diffusers also have a sleek appearance that adds a modern touch to vehicles.

  • 2. Glossy and Matte Finish Diffusers

    Some aftermarket Ford Focus ST rear diffusers have a matte or glossy finish. A matte finish appeals to many people because of its understated appearance. On the other hand, a glossy rear diffuser reflects light and gives vehicles a luxurious look.

  • 3. Quad and Dual Exhaust Rear Diffuser

    Another popular type of rear diffuser is the quad and dual exhaust diffuser. A quad exhaust diffuser comes with four exhaust pipes, while the dual exhaust diffuser has two exhaust tips. The quad exhaust diffuser creates an aggressive sound. It also improves the car's performance by enhancing exhaust flow. The dual exhaust diffuser, on the other hand, is easier to maintain and install compared to its quad counterpart.

  • 4. Sport Rear Diffuser

    A sport rear diffuser is designed to give vehicles a sporty look. It comes with sharp fins and a rugged design. The sport diffuser is ideal for car owners who participate in racing activities.

  • 5. Custom and OEM Diffuser

    OEM diffusers are manufactured by car manufacturers. They are designed to fit specific vehicle models. Custom diffusers, on the other hand, are made according to a client's specifications. The diffuser can be designed in any shape and size to meet a client's requirements.

Specifications and Maintenance of Ford Focus Rear Diffuser

  • Material

    Carbon Fiber: Carbon fiber is a high-end choice for rear diffusers because it is lightweight and very strong. It can make a car look more sporty and advanced. However, carbon fiber requires special care. While it is strong, it can be more easily damaged than other materials if a lot of force is used. It is important to be careful not to hit or put too much pressure on carbon fiber parts. If a small crack or scratch does occur, it is important to fix it right away. Water can get into these tiny openings and cause the fiber layers to separate over time. Regular cleaning with mild soap and inspections for any damage are needed to prevent this from happening.

    ABS Plastic: ABS plastic is a common material used for car parts. It is a good choice for rear diffusers because it is strong and can handle impacts without breaking easily. ABS plastic is also less costly than carbon fiber, so it is often used for diffuser kits that are more budget-friendly. ABS plastic is not as lightweight as carbon fiber, though. While it can improve aerodynamics compared to having no diffuser, it will not make the car as speedy and fuel-efficient as a carbon fiber diffuser would. For example, a carbon fiber diffuser may reduce drag by a certain percentage, making the vehicle more efficient. In contrast, an ABS plastic diffuser may provide some benefits but to a lesser extent due to its heavier weight.

    Polypropylene: Polypropylene is another type of plastic often used in car parts. It has properties like ABS plastic, such as being resilient and impact-resistant. Polypropylene is sometimes used for lower-cost diffusers or in regions where there are strict rules about car parts. It is a good choice for those who want to improve their vehicle's performance without spending too much. One advantage of polypropylene is that it can withstand heat better than some other plastics. This is important because the part of the car closest to the road can get very hot from driving. A polypropylene diffuser will last longer in that high-temperature area compared to plastics that are not as heat-tolerant.

Polyurethane: Polyurethane is a versatile polymer material that is often used for flexible car parts. It may be used for rear diffusers that require some bending without breaking. For example, the blades or fins of a diffuser can be made from polyurethane to allow them to flex slightly in the wind without snapping off easily. This is because the flexible design can help the diffuser withstand strong gusts better than rigid pieces would.

Ford Focus rear diffusers require regular maintenance to continue working well. They should be cleaned every few weeks to prevent dirt from building up. A soft sponge with soapy water or a special car cleaning spray can be used. It is important to avoid using products that have a lot of alcohol in them. Alcohol can damage certain types of plastics used in the diffuser over time.

It may also be good to apply a protectant once in a while. Look for sprays or creams made specifically for car parts. These will help keep everything looking nice while shielding against the weather and sun's rays. If any bolts or screws become loose, they should be tightened right away. Driving on bumpy roads or hitting curbs can cause pieces to come undone. A quick inspection after such incidents is wise.

With proper care, the diffuser will last a long time and keep the car stable at high speeds. However, if major damage occurs, it is best to replace the entire diffuser. Trying to fix individual fins or blades that are broken may not work well. Plus, the repaired areas may not match how the diffuser originally looked.

How to Choose Ford Focus Rear Diffuser

When shopping for a Ford Focus rear diffuser, business buyers should consider the following factors:

  • Ease of Installation

    Some rear diffusers require extensive modifications to the vehicle, which can make installation complex and time-consuming. Choose a diffuser that is easy to install with minimal modifications for quick and cost-effective installation.

  • Material Considerations

    Rear diffusers are typically made from ABS plastic, carbon fiber or fiberglass. ABS plastic is durable and resistant to impact, making it a popular choice for everyday driving. Carbon fiber diffusers are lightweight and provide superior aerodynamic benefits but can be more expensive. Fiberglass is an affordable option but may not be as durable as ABS plastic or carbon fiber.

  • Style and Aesthetics

    Select a rear diffuser that complements the overall style of the Ford Focus. Consider the color, finish and design features to ensure a cohesive and visually appealing appearance. Whether it's a sleek and modern look or a more aggressive and sporty design, choose a diffuser that matches the desired aesthetic.

  • Compatibility with Other Mods

    If other modifications exist, such as a modified exhaust system or a custom body kit, ensure the rear diffuser is compatible with them. This will maximize the performance benefits and create a unified look.

  • Test and Reviews

    Look for testimonials or reviews from other customers who have purchased and installed the same rear diffuser. Their experiences can provide valuable insight into the product's quality, performance and ease of installation.

How to DIY and Replace Ford Focus Rear Diffuser

Replacing a rear diffuser on a Ford Focus is a straightforward process that can be done with basic tools. Here's a step-by-step guide to replacing a rear diffuser:

  • Gather the necessary tools: Before starting the replacement, make sure to have the following tools on hand: a socket wrench set, screwdrivers (flathead and Phillips), torque wrench, and any specialty tools required for the specific diffuser model.
  • Park the car on a level surface: Find a flat, well-lit area to park the car. This ensures stability during the replacement process. Engage the parking brake and ensure the car is in gear (manual transmission) or in park (automatic transmission).
  • Lift the car: Use a hydraulic jack or ramps to raise the rear end of the car. Ensure the jack or ramps are placed on the designated jack points according to the manufacturer's instructions. Allow the car to be lifted to provide adequate clearance for working under the vehicle.
  • Remove the fasteners: Turn the car around and open the trunk. Use a socket wrench or screwdriver to remove the bolts, screws, or clips securing the old diffuser. Refer to the car manual or diffuser installation guide for the exact fastener locations. Keep track of the removed fasteners, as they will be used to install the new diffuser.
  • Carefully pull off the old diffuser: Gently pry the old diffuser away from the rear bumper, starting from one side and working your way around. Be cautious not to damage the bumper or surrounding components.
  • Prepare the new diffuser: Clean the area where the new diffuser will be installed. Remove any adhesive residue or dirt from the bumper surface. If the new diffuser requires any additional components (e.g., mounting brackets, adhesive strips), install them according to the manufacturer's instructions.
  • Position the new diffuser: Align the new diffuser with the rear bumper, ensuring proper fitment and alignment with the exhaust outlets and other features. Start by inserting the clips or tabs into their corresponding slots, then press the diffuser firmly against the bumper.
  • Secure the fasteners: Use the previously removed bolts, screws, or clips to secure the new diffuser. Tighten the fasteners evenly and securely, but be careful not to overtighten, which may cause damage to the diffuser or the bumper.
  • Lower the car: Carefully remove the jack or ramps and lower the car to the ground. Ensure all tools and loose parts are removed from underneath the vehicle before doing this.

It's always recommended to consult the Ford Focus owner's manual or a professional mechanic for specific instructions related to the particular Focus model and rear diffuser being installed.
