Bests & Worsts Reviews from Amazon

Are use this product to find my broken charge pipe on my BMW 335xi. It was nighttime and I lost all boost pressure and I happen to have this in the car so I pulled over and found that the entire charge pipe blew off without this I wouldn’t have figured it out since it has the lights on the end of it so later on as you can see in the second photo I saw in the daytime a completely cracked open charge pipe. This definitely save me from driving and potentially destroy my engine by ingesting stuff.
