O.S. Engines have released the 4th version of their popular 12TG touring car class engine. The durability of the engine has been improved by adopting the conrod from one of their high end competition OS Speed T12 engines with the crankcase changed accordingly. The shape of the piston is also different and lighter, ensuring a smooth power delivery is achieved. The final changes are only cosmetic with the blue cooling head received a newly designed laser marking. Available as a solo engine and as a combo with the TT02 EFRA2690 pipe and EX Manifold MT02.
