Why Use Exoracing Bumper Air Diffusers?

If you are running a high-performance car or using it in a drag application, you will know that air will sit in the rear bumper at high speeds, creating the parachute effect. This will slow you down, so the most common thing to do is install bumper air diffusers to relieve this air.

The air diffusers work by drilling holes in the rear bumper and bolting our plate over the top for a clean appearance. Installing the bumper air diffuser kit will very quickly decrease air resistance in the bumper, increasing acceleration.

To be as lightweight as possible, the air diffusers are laser cut from high-grade 1.5mm aluminium sheets and have countersunk holes added for a perfectly flush fit. They have been designed to be 390mm x 102mm to fit as many bumpers as possible and allow for the biggest surface area without completely removing the rear bumper.

We also include a full-fitting kit of countersunk stainless steel bolts and nylon lock nuts to ensure the bumper diffusers do not move, even at speeds of over 200mph!

We have also added an installation guide for anyone unsure how to install these. If you want to see photos of them installed, head up to our pictures at the top. There, we have customer photos using our Exoracing bumper air diffusers and running drag times as low as 8.29 at 178mph at the time of writing.

Our bumper diffusers are available in black anodised and silver raw finish, ensuring their durability and longevity. Investing in these top-quality air diffusers can significantly improve your driving experience and take your drag racing times to the next level.

We now offer an Exoracing lifetime warranty on our bumper diffusers because we know you will not have any issues with them and want you to have a risk-free buying experience.

Exoracing Rear Bumper Air Diffuser Installation Guide:

Follow our quick and easy bumper air diffuser installation guide to get up and running as quickly as possible. If you are not competent with modifying your bumper or are unsure about any of the steps in this guide, please contact a professional to install it.

Things You Will Need For Installation:

  • Exoracing Bumper Air Diffuser Kit
  • 70mm Holesaw
  • Drill
  • 6mm drill bit
  • Spirit Level
  • Masking Tape
  • Sharpie or marking tool
  • Allen Key
  • 8mm Socket and ratchet, or 8mm spanner

How to Install:

  1. First, ensure the bumper is clean, otherwise the masking tape will not stick to the surface. We recommend using a smear-free cleaner, such as a glass cleaner, that leaves no residue.
  2. Make sure the car is perfectly level, and using the masking tape, hold the bumper air diffusers in the correct location where you want to install them.
  3. Use a spirit level to ensure they are perfectly straight. If the car isn't 100% level, use a tape measure to measure down from points on the bumper.
  4. Next, once you are happy with both locations, sharpie around the centre of the three large air holes and dot each hole you need to drill. Before drilling, please ensure there is nothing behind the bumper that you can puncture. If there is, you may be better off removing the bumper before cutting.
  5. Remove both bumper air diffusers, use the 70mm hole saw to cut out the six large holes, and drill through all 20 holes using a 6mm drill bit.
  6. Hold the bumper diffuser back up to the bumper with the countersunk holes facing outwards, install the far left and far right countersunk bolts, and place a nut on the back, finger tight.
  7. To fully tighten the far left and far right bolts, use an Allen key from the front and an 8mm socket from the back.
  8. Now they are held firmly in place, go ahead and repeat this step for both diffusers and install the rest of the bolts.
  9. If you removed the bumper, please reinstall it, and you are all done! If you have any photos, please tag us on social media using #Exoracinguk, as we would love to see the diffusers in action!
