Prevents costly airbox explosions, installed with the engine and air box in place. 911 engines since 1973 have had the bad habit of backfiring and blowing a hole an the air box. 911 POP VALVE is installed inside the air box and when a backfire occurs the valve will instantly open and release the backfire pressure. The POP VALVE then automatically closes and the angine continues to run. The POP VALVE has no effect on the performance or fuel mileage.

Engine Tuning Air Induction Kits – Unlock Your Porsche’s True Breathing Potential
An air induction kit is one of the most effective tuning upgrades for increasing power and responsiveness in your Porsche. Designed to replace restrictive stock airboxes and piping, these systems improve airflow, reduce intake resistance, and deliver cooler, denser air to the engine. The result is a sharper throttle response, enhanced torque, and a more engaging driving experience.
At Design911, we stock a premium range of performance air induction kits engineered for Porsche models across all generations — from classic 911s to modern Cayman, Boxster, and Taycan models. Manufactured from lightweight, heat-resistant materials with precision-fit components, our high-quality induction systems ensure optimal performance and a refined induction sound that complements your Porsche’s character.
Whether you’re aiming for track-ready performance or improved road dynamics, our air induction kits provide the perfect balance of power, reliability, and sound enhancement.
What Do Air Induction Kits Do?
Air induction kits optimise your Porsche’s intake system by increasing the volume and quality of air reaching the combustion chamber.
Core Functions:
- Increase
airflow efficiency to improve engine breathing and power output.
- Reduce
intake temperatures for denser air and better combustion.
- Enhance
throttle response for sharper, more immediate acceleration.
- Deliver
a sportier induction sound during acceleration.
- Improve fuel efficiency and overall engine performance.
When properly installed, an upgraded induction system can boost both performance and engine responsiveness, making it one of the best value-for-performance modifications available.
Why Do Induction Kits Fail or Require Replacement?
Like all high-performance components, air induction kits and filters are subject to environmental wear and heat exposure over time.
Common Causes of Failure Include:
- Clogged
or damaged filters reducing airflow and power.
- Cracked
intake pipes causing air leaks and inaccurate sensor readings.
- Heat
soak from poor insulation or worn heat shields.
- Contaminant
build-up on intake elements and sensors.
- Loose fittings or seals resulting in unmetered air entering the system.
Symptoms of a failing induction system include loss of performance, uneven idle, whistling noises, or increased fuel consumption — all indicators that maintenance or replacement is needed.
Why Upgrade or Replace with Performance Induction Components?
Replacing worn parts or upgrading to a high-performance induction system ensures consistent airflow, reduced restriction, and improved power delivery.
Key Benefits:
- Increases engine power and torque.
- Improves throttle response and drivability.
