That $160 price is for the pulley for the 2.0 and 2.4 engines.
The pulley for the 1.4 is $239. This is the Road Race Lightweight pulley.
I installed this pulley on mine and now the engine/trans just act like a completely different set-up. I do have the 1.4 with the DDCT. I also have torks hot/cold pipes and an Injen CAI. The lag is now completely gone. And, for city stop & go driving, I can get the tranny to shift now below 2500 rpm, in auto mode. Top end acceleration is greatly improved also. The weight difference between stock and the lightweight is less than half as compared to the OEM pulley. RRM's is @ 1.67 lbs while OEM is @ 3.5 lbs. And, if you have the CAI already, you can replace the pulley with the car on the ground and do it from above. It takes about 15 minutes.
