These boost leak testers fit a 2.25" turbo inlet, the size used by small turbos on 4-cylinder cars and some twin turbo setups. To check your size, remove the intake and measure the outside diameter of the turbo inlet flange or the pipe you'll test on with a tape measure or calipers. If it reads 2.25", this is your size.

Each tester has a CNC-machined 6061 billet aluminum end cap, a high-quality silicone coupler, a stainless T-bolt clamp and a liquid-filled gauge so you can see exactly how much pressure is in the system. Start at about 5 PSI and work up toward your normal boost.

Not sure about the size? Text a photo with a tape measure across the inlet to 248-403-8512. Every order placed by 5pm PST Monday to Friday ships the same day, and shipping is free on orders over $50.
