Peugeot 306 VTS air intake kit: fresh air, not radiator air
This direct air intake kit replaces the stock airbox of the Peugeot 306 VTS with a high-flow filter protected by a steel heat shield. That's the difference compared to a simple cone filter left exposed in the engine bay: here, the filter is insulated from the heat of the engine block and supplies the engine with cool air. On a naturally aspirated four-cylinder engine that lives at high revs, this matters.
Why choose this air intake kit
- Steel heat shield: the filter is surrounded by a metal box that blocks engine heat.
- High-flow filter: filtering surface area far superior to that of a stock paper cartridge.
- Washable filter: it can be cleaned and re-oiled, so it doesn't need to be thrown away after every service.
- Intake sound: the intake roar becomes clearly audible when you step on the gas.
- Dedicated 306 VTS kit: airbox custom-made for the 306 VTS engine layout.
Airbox and air filter: what a proper box really changes
A direct intake without protection draws in air from the engine bay, which can exceed 60°C after a few miles. Hot air is less dense, and therefore contains less oxygen: the expected benefit evaporates. The airbox with a heat shield restores common sense: the filter is enclosed, the air comes from the front of the vehicle and stays close to ambient temperature. This is the setup found on serious Peugeot 306 builds, alongside upgraded exhaust systems and ignition systems.

Installation and maintenance
Start by removing the stock airbox and its hose, then position the heat shield on the existing mounting points before fitting the filter and connecting the intake hose. Allow approximately 1 hour with a set of combination wrenches and a screwdriver. Ensure the hose clamps are properly sealed: an unfiltered air leak is the most common installation error. The filter should then be cleaned every 15,000 to 20,000 km, or more frequently when driving on dusty roads.
Frequently asked questions
Does an intake kit add power?
On a stock engine, the gains remain modest and are felt mainly at high revs. They become noticeable when combined with an upgraded exhaust system and appropriate engine tuning.
Why is a heat shield essential?
Because an exposed filter draws in hot air from the engine bay. The shield insulates the filter and preserves the density of the intake air.
Do you replace the filter like a paper filter?
No, it is washable. Cleaning and re-oiling every 15,000 to 20,000 km is enough to restore it to like-new condition.
Is the installation reversible?
Yes. The stock airbox can be reinstalled exactly as it was; nothing is cut or drilled into the vehicle.
Will this kit pass an MOT?
An MOT checks emissions and the absence of leaks, in particular. A properly sealed and securely fitted installation generally poses no problems, but compliance should still be assessed according to your vehicle.
Give your 306 VTS back the breath it had when it left the factory: a well-designed airbox means fresh air every time you rev it up.
