Porsche Duct Spoiler & Air Scoop
At Design911, we supply a specialist range of duct spoilers and air scoops for Porsche models, designed to manage airflow around brakes, radiators and the underbody so your car can cope more confidently with demanding road and track use.
Why do Porsche Duct Spoiler & Air Scoop components matter?
Duct spoilers and air scoops help guide cooling air exactly where your Porsche needs it – typically towards brake discs and calipers, radiators or specific underbody zones. When these parts are cracked, missing or poorly fitted, airflow can escape, cooling becomes less effective and surrounding components may run hotter than intended. Refreshing tired ducting helps your Porsche feel better looked after and supports consistent performance when driven enthusiastically.
- Keep airflow directed to key areas such as brakes and radiators
- Help manage heat during spirited road driving and track days
- Reduce the impact of damaged, scraped or loose original ducting
- Support long-term reliability of nearby components exposed to heat
Common options & kits
Individual replacement parts Specific ducts, scoops or spoilers that replace a single damaged or missing item without changing the rest of the system.
- Ideal when only one side or section is cracked or lost
- Lets you restore airflow to a specific brake, radiator or underbody area
- Useful after minor impact or kerb damage
Matched sets or pairs Left and right ducts or front and rear components supplied together so both sides are renewed for consistent airflow.
- Ensures balanced cooling from side to side
- Reduces the chance of one old, brittle part failing later
- A neat option when upgrading brake cooling as a package
Complete ducting kits Grouped components that provide an integrated cooling solution, often aimed at fast-road or track-focused Porsches.
- All key pieces specified in one kit for a given bumper or undertray setup
- Saves time cross-referencing individual part numbers
- Ideal when optimising airflow as part of a wider performance build

When should you review or replace your Porsche duct spoiler & air scoop?
Checking duct spoilers and air scoops periodically helps you spot impact damage or missing pieces before they compromise airflow to key components.
- Visible cracks, broken mounting tabs or completely missing duct sections
- Scraping damage from speed bumps or kerbs, especially on lowered Porsches
- Loose or rattling panels that suggest failed clips or fixings
- Evidence of overheated brakes or high coolant temperatures where cooling may be marginal
If any of these apply, it is a good time to review the duct spoilers and air scoops on your Porsche and replace anything damaged so cooling airflow is properly controlled again.
