BILITOOLS 9-Piece Turbo System Leakage Tester Set Turbocharger Turbo Boost Leak Tester 1-3/8" - 3-1/2"

I used this on a vehicle with a boost leak and was able to easily find the leak with the help of this product. I had no idea what I was doing but with little help from forums I was able to hook this up correctly and fix the boost leak.

This leak tester helped me locate a boost issue on my Audi A5 without paying a shop for diagnostics. Inexpensive, easy to use, nice case.... what more could you ask for? Highly recommend!

i have used this several times on my trucks and my friends it has made finding boost leaks a breeze and it’s pretty well built for the price

You need some of that while plumbers tape for a compressor fitting. Also, after you screw the compressor fitting on, the pressure regular part won't fit in the case anymore. That was was specifically fairly disappointing. However, if you own a turbo car, you should probably own one of these. Really helpful for chasing down boost/vacuum leaks.

I received it quickly.

Seems like a decent product. The pressure regulator seems to bottom out at 20psi minimum, which is disappointing, but overall it functions well enough.

This product does not have ribs which are required when pressure testing. The pucks will shoot off. These are dangerous. Buyer beware

It worked perfectly. Found the leak and remediated the problem.
