Valve Intake
34mm

Does the oil consumption increase with increasing mileage? Do you notice a loss of power or "engine ringing"? Then it is high time to check the valve guides and seats. In most cases, too much play in the valve guides and the associated increase in compression are responsible for these problems.

Of course, Jochen Siebenrock has also included products of outstanding quality in its range of accessories. It is therefore not surprising that the company Intervalves Technologies AG, based in Switzerland, was chosen as a partner for the manufacture of the valves.

Valves in top quality.
The shafts of the intake valves are coated with hard chrome and hardened at the ends. The exhaust valves are stellite armor-plated.

TIP
We recommend to replace the valve keeper and valve spring each time the valves are changed.

Price per piece.
