Just as it says. I have a Bazzaz, brand new with built in quickshifter. Comes with the o2 sensor elimintor as well. These are much better than dynojet as they fuel all 8 injectors. To get the same result with dynojet you need a PCV at £315. A SFM at £249. A shifter at £189 and a rod at £15. This is just the z-fi Q/S NO TRACTION CONTROL. Brand new with the Rod. Complete. Retails around £425. £325 delivered
