Boost leak test kit

This is a boost leak test kit with sizes ranging from 2in all the way up to 3.5in in .25in increments so there is a size for pretty much any vehicle on the market.

There are two main parts in all the sizes, a cap with a 1/2in hole for the valve stem you will need to install (or you can use an air blow gun with rubber end and just press up against the hole) this part you put on the inlet of your turbo with a boost hose and hose clamps.

And the second optional part is a block off cap for the other end of your boost pipe (where it would connect to the intake manifold), this part is not always necessary because the intake and engine usually hold enough pressure to test your system effectively, but if for some reason your engine values or manifold are leaking air too fast you can use this block off plate to isolate only the boost pipes to find leaks more effectively.
