Review on 🔧 UXcell 4pcs Plastic Fuel Injector Nozzle 195500-4450 N3H3-13-250A for Mazda RX-8 2004-2009 1.3L Manual Transmission - New Model by Patrick Bacho

I installed the injectors and calibrated my 425cc setting but immediately had idle issues and misfires. I couldn't idle above 11:1 and the car ran rich when driving and accelerating. At the same time I installed new spark plugs which went black and burned 2/4 full after only 11 miles of driving and about an hour of idle adjustment. I tried a different set of stubs and found the same thing after about the same amount of time. Two of these nozzles consistently flow more than the others. I have requested a replacement from Revain and will update this review with a positive kit replacement experience.
