CSP 25HP+30HP Billet Rocker Covers With Machined Logo (M18x1.5 Fitting)

Billet Rocker Covers from CSP with Machined CSP Logo and M18x1.5 tapped holes for breather fittings  for 25HP and 30HP VW Aircooled Engines

Enhance your classic VW engine with CSP Products Billet Rocker Covers, specially designed for 25HP and 30HP VW aircooled engines originally fitted to VW Beetles, Karmann Ghias, and Splitscreen Buses before 1960. These rocker covers combine superior design, advanced manufacturing, and high-quality materials to offer the best performance and aesthetics for your vintage vehicle.

Features and Benefits:

1. Advanced CNC Machining: CSP Products rocker covers are CNC-machined from billet aluminum, ensuring precise dimensions and perfect fitment. The latest CNC technology allows for the largest possible inner dimensions to accommodate all common rocker arms while maintaining minimal outer dimensions.

2. Heat Dissipation and Lightweight: The billet aluminum construction provides excellent heat-dissipating properties, keeping your engine cooler. Despite their durability, these covers are incredibly lightweight, with the lightest version weighing just 544 grams, only 241 grams more than a standard VW valve cover.

3. Perfect Sealing: Designed for reliability, these rocker covers use O-ring seals and special shaft screws with additional O-rings, ensuring a perfect seal and preventing oil leaks. In emergencies, cork seals can also be used.

4. Reinforced for Rigidity: Organic reinforcement ribs on the inside of the covers provide maximum rigidity, ensuring stability and strength even under extreme conditions.

5. Stylish and Functional Design: The rocker covers feature a black hard-anodized finish for corrosion resistance and a sleek look. A machined CSP Products logo adds a touch of style, while a generously dimensioned, reinforced area allows for the optional installation of breather fittings (available with M18x1.5 or 3/8 NPT threads).

6. High-Quality Hardware: The included hardware is of the highest quality, with special 10.9 nuts to ensure the operational reliability of the engine even at extreme RPMs and high rocker arm ratios.
