Purpose and technical specifications

The presented cylinder head is designed for use with the TFSI petrol engine in the Volkswagen Polo 6R generation, specifically the 1.8 TFSI version with the DAJA engine code. The design is intended for operation in a petrol-powered system, ensuring compatibility with factory engine parameters and proper integration with engine accessories.

Its original Volkswagen origin ensures the maintenance of correct intake and exhaust port geometry, proper valve guidance, and compatibility with standard timing and ignition system components. As a result, the cylinder head provides a solid foundation for engine repair following mechanical or thermal damage.

Benefits of using an original cylinder head

Using a factory cylinder head in a TFSI engine offers a range of practical benefits:

• maintenance of the engine's original performance parameters,
• reliable fitment to the engine block and accessories,
• reduced risk of compression and combustion system sealing issues,
• easier future diagnostics and servicing due to compliance with manufacturer documentation.

For workshops and individual users, this means a predictable installation process and the ability to restore engine efficiency without the need for aftermarket solutions with uncertain specifications.

Application in the TFSI petrol engine

TFSI engines running on petrol require a precisely manufactured cylinder head that ensures adequate cooling, lubrication, and stable valve operation under higher loads. The presented cylinder head is adapted to such operating conditions, which helps maintain proper engine refinement and correct cooperation with the turbocharger and fuel injection system.

By maintaining factory tolerances and design solutions, the cylinder head performs well both in daily city driving and during more dynamic use typical of TFSI units.

Condition and service application

The item belongs to the Cylinder Heads category and is primarily intended for service applications: post-accident repairs, engine overhauls, and replacements in cases of damage resulting from overheating or timing system failure. The used nature of the product allows for cost-effective repair while maintaining the original design specifications.

Before installation, standard workshop procedures are recommended: checking the mating surface flatness, verifying channel tightness, and matching it to the specific accessory configuration of the vehicle. This approach facilitates trouble-free engine startup after repair and limits the risk of additional service downtime.
