Tecnostar produces over 6 million valves every year; just under half of these are destined for the spare parts market. Production includes valves and valve-guides for the engines of passenger vehicles and medium and heavy goods vehicles.
Tecnostar usually has valves and valve-guides for the most common European and Asian cars, and for medium-to-heavy goods lorries manufactured by Iveco, Volvo, Mercedes and Scania.
