Someone can say me if this is possible? Skunk2 says only test in your american models h22a1 and h22a4, but in youtube i see a lot of videos of h23 pro1, h22a7 pro1, h22 jdm...etc

My friend buy him obx h22a1/h22a4 cams for your h22a2 european and they were shorter than oem, so i dont know if skunk is the same
