La soupape de carburant PPE Race, fabriquée en acier inoxydable, remplace l'origine ou une soupape de surpression calée. Cette soupape aide à maintenir la pression de la rampe d'alimentation en carburant dans des conditions de charge élevée du moteur. Il élimine les codes DTC potentiels de faible pression de rampe de carburant P1093 ou P0087 (faible pression de rampe de carburant pendant l'enrichissement de puissance) qui sont causés par une pression insuffisante du ressort de la soupape de surpression (PRV). Cela conduit à une ouverture trop précoce de la vanne, ce qui entraîne le retour de quantités excessives de carburant dans le réservoir.
