Exhaust catalytic converter with particulate filter. Porsche 9YB Cayenne turbo E-Hybrid  ❭  PAB2548

Sport catalytic converter with Lambda sensor hole. 100 cell. Polished stainless steel.



Fits:
Porsche 911 2.7L 1975-89

Please note: These sport cats will make your car sound louder than with stock cats. If you have ,or intend to install sport silencers, you may find the car is a bit loo loud. We recommend to use one sport exhaust component if you are concerned about decibel levels.

NOTE: Sports catalytic converters and bypass pipes do not have type approval and are not legally permitted for use on vehicles manufactured after 1st March 2001 in the United Kingdom. They are not MOT compliant and must not be used on public roads. These components are intended for race and track use only. If you are located outside the UK, please consult your local laws and regulations to ensure compliance.

Blanking Plug For Oxygen Sensor Hole.
Securely seal an unused oxygen sensor port with this OE Match Blanking Plug for Oxygen Sensor Hole. Designed for compatible exhaust applications, this plug is used when an oxygen (lambda) sensor mounting hole is present but a sensor is not required for the particular vehicle, exhaust configuration, testing setup or application.  

M 18 x 1,5 x 18
23mm in length

Oxygen sensor ports are threaded openings in the exhaust system that normally accommodate a lambda sensor. When the port is not being used, it must be properly sealed. Leaving the opening exposed can allow hot exhaust gases to escape and may permit moisture and contamination to enter the exhaust system.  

What This Product Does:

• Seals an unused oxygen or lambda sensor mounting hole.
• Prevents exhaust gases escaping through an unused sensor port.
• Helps maintain the integrity of the exhaust system.
• Protects the threaded sensor opening from dirt and contamination.
• Helps reduce moisture entering through an unused port.
• Allows an exhaust component with an oxygen sensor boss to be used where a sensor is not required.
• Provides a removable solution if an oxygen sensor is required later.
• Replaces a missing, damaged or corroded blanking plug.
• Provides an OE-style solution for compatible exhaust applications.  

Symptoms Of Wear Or Failure:

• Exhaust gases leaking around the plug.
• A ticking or blowing noise from the oxygen sensor port.
• Black soot deposits around the plug or threaded opening.
• A strong exhaust smell near the affected area.
• The plug has become loose.
• Visible corrosion or deterioration.
• Damaged or stripped plug threads.
• A plug that can no longer be securely tightened.
• The original blanking plug is missing.
• An oxygen sensor has been removed and the port remains open.
• Heat or exhaust staining around the sensor boss.  

Why Replacement Matters:

• An unused oxygen sensor hole should never be left open during normal engine operation. Exhaust gases are extremely hot and can escape through the opening at high velocity, potentially damaging nearby components and creating excessive noise.
• An exhaust leak can also affect the correct operation of the exhaust system. Depending on the location of the unused port and the vehicle's configuration, unwanted air entering the exhaust may also interfere with exhaust-gas measurements or diagnostic testing.
• The threaded sensor boss itself can deteriorate if left exposed. Dirt, moisture and corrosion may damage the threads, making installation of a future oxygen sensor more difficult or requiring repair of the sensor mounting point.
• A loose or damaged plug can produce similar problems. Soot deposits around the port are often an indication that combustion gases are escaping past the sealing surface or threads.
