Dual Port Cylinder Shrouds for Type 1 VW, Black

OVERVIEW

When it comes to maintaining the health and longevity of your air-cooled engine, nothing is more critical than proper airflow management. These EMPI Dual Port Cylinder Shrouds, finished in a classic factory-style black, are essential components of your Volkswagen''s cooling system. Often referred to as ''''coolie tins'''' or over-cylinder tinware, these shrouds are designed to capture the high-velocity air generated by your cooling fan and direct it precisely over the cooling fins of your cylinders and cylinder heads. In an air-cooled environment, heat is the enemy, and missing or damaged tinware is a leading cause of localized hotspots, warped heads, and premature piston ring failure. By installing these fresh, precision-stamped shrouds, you are ensuring that the thermal energy produced during combustion is efficiently stripped away, keeping your oil temperatures stable and your engine running at peak performance.

Constructed from high-quality stamped steel, these shrouds are specifically engineered for Type 1 dual-port engines. Unlike universal or single-port alternatives, these pieces feature the correct indentations and clearances necessary to accommodate the larger dual-port intake manifolds without interference. The durable black finish provides a clean, OEM-plus look that is perfect for a stock restoration or a high-performance sleeper build. Whether you are building a fresh 1600cc long block from the ground up or you are replacing old, rusted, or bent tinware during a routine tune-up, these EMPI shrouds offer the perfect blend of structural integrity and thermal efficiency. Don''t let your engine suffer from "air leaks" in the cooling system; sealing the path of the air from the fan shroud to the cylinders is the most cost-effective insurance policy you can buy for your VW.

PRO TIPS

1. Check Your Air Deflector Plates

A common mistake during engine assembly is forgetting the small "air deflector plates" (also known as coolie tin deflectors) that sit directly under the cylinders between the pushrod tubes. These shrouds work in conjunction with those lower plates to create a pressurized "wind tunnel" effect. If the lower plates are missing, the air will simply blow past the cylinders rather than wrapping around them. Always ensure those lower deflectors are snapped securely onto the cylinder studs before you bolt down these top shrouds for maximum cooling efficiency.

2. Ensure a Tight Seal at the Fan Shroud

For the cooling system to work as designed, it must be airtight. When installing these shrouds, pay close attention to where they meet the main upright fan shroud. If there is a gap, you are losing valuable air pressure. We recommend using high-quality hardware and ensuring the shrouds are tucked tightly into the fan shroud grooves. If you notice any gaps, you can use a small amount of engine-safe RTV or specialized tinware seals to ensure that every cubic foot of air moved by the fan is forced down over the cooling fins rather than escaping into the engine bay.

3. Manage Your Spark Plug Wire Clearances

Because these are dual-port shrouds, they sit close to the intake manifolds and the spark plug holes. Before you tighten the mounting screws completely, test-fit your spark plug wires and boots. Ensure that the wires are not rubbing against any sharp metal edges of the shrouds, as engine vibration can cause the tinware to saw through the insulation over time, leading to a misfire. Using rubber grommets in the spark plug wire holes is a pro-level move that prevents wire chafing and helps maintain the "sealed" environment required for the air-cooled system to operate at its best.
