Bosch 0290004502 Distributor Cap for Porsche - 928

The Bosch 0290004502 distributor cap is a precision-engineered ignition component designed for Porsche 928 applications. This genuine Bosch distributor cap serves as a critical part of the vehicle's ignition system, routing high voltage from the ignition coil to the appropriate spark plug in each cylinder to ensure proper firing order and efficient engine operation.

Key Features:

• Constructed from high dielectric strength, glass/mineral reinforced polyester resin for superior resistance to electrical breakdown
• Engineered to stringent OE specifications for exact fit and function
• Solid brass terminals provide excellent conductivity and resistance to electrical pitting and corrosion
• Advanced design minimizes carbon tracking for reliable spark distribution
• Direct replacement for worn or damaged original equipment distributor caps

Regular inspection and replacement of the distributor cap is essential for maintaining optimal engine performance. A cracked or damaged cap can cause arcing inside the distributor, resulting in misfires, rough idling, poor acceleration, and reduced fuel efficiency. Bosch quality ensures long-lasting reliability and peak ignition system performance.
