The valve train of your tuned V10 has to endure a lot if you experience an extreme increase in performance, for example for a turbo conversion. Enormous forces and temperatures act here, which the series valves are unfortunately not up to. So that the valves continue to work perfectly even at high speeds, together with boost pressure, you should use our valves. The kit consists of special inlet valves. This means that a higher engine speed with boost pressure is not a problem. So you can enjoy full performance without worrying about valve flutter or broken valves! Features: Higher engine speed possible Stable for boost pressures up to 2 bar High temperature resistance Strong tear resistance Heat treated material High strength steel Quality and workmanship at the highest level The kit also consists of 20 intake valves Similar to illustration.
