Measure the outside diameter of your turbo inlet, then tap the size.
Text us the turbo or a photo of the inlet and we'll point you to the right kit.
Every tester here is sized to one turbo inlet. If you work on lots of different turbos, a shop kit covers a range of sizes in one box.
Measure the outside diameter of your turbo inlet (or the pipe the tester goes on) with a tape measure or calipers, then tap that size above. Between sizes? Text a photo with the tape across the inlet to 248-403-8512, or see What size do I need?
A tester kit is ready to go: billet end cap, gauge, silicone coupler and T-bolt clamp. An end cap is the billet cap and gauge without the silicone coupler, for when you already have one. Brand-specific testers are made to fit Garrett GT/GTX, Precision and BorgWarner turbo inlets.
Yes. The 5", 5.5" and 6" kits fit large frame and diesel turbos. You can also shop pickup trucks and semi trucks by vehicle, and for charge air coolers see the CAC pressure tester.
Order by 5pm PST / 8pm EST Monday–Friday, or 2pm PST / 5pm EST Saturday, and it ships the same day. US orders over $50 ship free.
Universal boost leak testers are sized by turbo inlet, not by vehicle, so they work on almost any turbocharged engine: custom builds, upgraded turbos, swaps and anything we don't make a vehicle-specific tester for. They come in 13 sizes from 1.5" to 6". To pick yours, find where you'll test (usually the turbo inlet, or the intake pipe just before the turbo) and measure the outside diameter straight across the opening with a tape measure or calipers. Then choose that size below. Every tester is CNC-machined from 6061 billet aluminum with an anti-slip beaded end, a liquid-filled gauge and a T-bolt stainless clamp, and is backed by a lifetime warranty. If you work on several cars, a shop kit covers a range of sizes in one case and costs less than buying the testers one by one. Between sizes or not sure what you measured? Text a photo with a tape across the inlet to 248-403-8512.
