The A-8 entered production in February 1944, powered either by the standard BMW 801 D-2 or the 801Q (also known as 801TU). The 801Q/TU, with the "T" signifying a Triebwerksanlageunitized powerplant installation, was a standard 801D with improved, thicker armour on the BMW-designed front annular cowling, which still incorporated the BMW-designed oil cooler, upgraded from 6 mm (.24 in) on earlier models to 10 mm (.39 in). Changes introduced in the Fw 190 A-8 also included the C3-injection Erhöhte Notleistung emergency boost system to the fighter variant of the Fw 190 A (a similar system with less power had been fitted to some earlier Jabo variants of the 190 A), raising power to 1,980 PS (1,953 hp, 1,456 kW) for a short time.
