Featuring a polished chrome 5-bar grille with a contrasting black mesh insert, this OE-style assembly provides unrestricted airflow to the engine compartment while protecting vital engine components from leaves, debris and foreign objects.  

Fits:

• Porsche 911 1965-1968 2.0L / 912 SWB (F)

Manufactured from high-quality corrosion-resistant metal with a durable polished chrome finish and robust black mesh insert, the grille is engineered to withstand exposure to UV rays, moisture, engine heat and road contaminants. Precision-manufactured for direct OE-style installation, it ensures an accurate fit within the rear engine cover while delivering the authentic factory appearance expected from a classic Porsche restoration.  

What This Product Does:

• Allows cooling air to enter the engine compartment.
• Helps maintain efficient airflow to the air-cooled engine.
• Protects the engine compartment from leaves and road debris.
• Restores the original appearance of the rear engine cover.
• Features an authentic 5-bar chrome grille with black mesh insert.
• Provides factory-style fitment and alignment.
• Enhances both appearance and engine cooling efficiency.
• Forms an essential part of the rear engine cover assembly.

Symptoms Of Wear Or Failure:

• Bent or damaged grille bars.
• Corrosion or pitting of the chrome finish.

Why Replacement Matters:

• A damaged grille can allow leaves, stones and debris to enter the engine compartment, potentially affecting cooling efficiency and increasing maintenance requirements. Corrosion or poor fitment can also detract from the appearance and value of a classic Porsche.
