Turbo Boost Leak Tester Kit

$156.00
About this product

The KWI Boost Leak Tester is a complete diagnostic tool for identifying and eliminating boost leaks on any turbocharged Can-Am or Polaris RZR — stock or big turbo. Whether you're chasing a power loss, prepping for a dyno pull, verifying a new turbo install, or confirming your system is fully sealed before a race, this tool takes the guesswork out of boost system diagnostics and gets you an answer fast.

Installation is straightforward — remove your air filter, install the tester directly to the turbo inlet, and pressurize the system up to 60 PSI. The intercooler, plenum, and charge tubes are all tested in one step, giving you a complete picture of your boost system's integrity without pulling the machine apart. The kit includes multiple boot sizes and clamps to fit nearly every OEM and aftermarket turbo setup, making it the most versatile boost leak tester on the market.

Boost leaks don't just cost you power — they drive up intake temperatures, corrupt your tune, and throw off clutch calibration in ways that are difficult to diagnose without the right tool. If your machine isn't performing the way it should and you can't find the reason, a boost leak is one of the first things to rule out. The KWI Boost Leak Tester makes that process fast, simple, and definitive.

Why it matters

A boost leak you can't find is power you can't make — and clutch calibration you can't trust.

Undetected boost leaks corrupt everything downstream — your tune, your temps, your clutch calibration, and your lap times. The KWI Boost Leak Tester pressurizes your entire system in one step so you know exactly where you stand before you ever hit the throttle.
