As the title says fitted my viper IK today, ive had the red parts painted at work the same colour as the car (iceberg silver). It took me about 6hours to fit, as i took the bumper off, nearside headlight out and all the old air box & cold air feeds out. I used a cold air feed from a renault master turbo, as it is ideal with a plastic elbow joint on the end to fix to the bottom grill, its also the perfect lengh. as for the performance you can tell its there it seems more responsive, & sounds just right. Its going for a run on the rollers next week. Im going to take some pictures of it tomorrow and post them on here for you lot to see. cheers Paul172
