Both share the same cylinder spacing. The latter EA113 was updated with Fuel Stratified Injection (FSI) direct injection, to be topped by the 2.0 TFSI used in the Audi TTS. Forty million engines have been produced. This range will eventually be superseded by the evolved version with heavy changes EA888 project, introduced with the 1.8 TSI/TFSI below, but the EA113 still remains in production. 1.2 TSI/TFSI (EA111) This engine is manufactured at the Škoda Auto plant in Mladá Boleslav identification parts code prefix: 03F, ID codes: CBZA, CBZB, CBZC engine displacement & engine configuration inline-four engine (R4/I4); bore x stroke: , stroke ratio: 0.94:1 – undersquare/long-stroke, 299.3 cc per cylinder, compression ratio: 10.5:1, peak pressures cylinder block & crankcase cast aluminium alloy,
