Burn Fuel. Use Oil. Make Heat.
Worse-case scenario is an intake leak that can cause your really expensive vintage American V-twin to go lean in one cylinder and melt a hole in the piston, gall rings, and gutter valves. Best-case with an intake leak is a cantankerous engine which refuses to be a consistently starting, idling, and running machine.
We're not saying that you have an intake leak; but what we are asking is how do you know you don't?
Our Intake Testers are designed to be used under vacuum to simulate real world conditions present within your intake system. Positive air pressure can also be used to inspect for a leak-free install- but the vacuum inspection is by far the cleanest, accurate, and most discreet method.
The 2 Bolt 6061-T651 aluminum Intake Testers feature an integrated quad-ring which provides a superior leak-free seal and allows a simple installation without fussing about with a gasket. The MIL-spec anodizing ensures a durable lifetime finish. Each Tester is supplied with the popular "industrial shape" quick-disconnect fitting and stainless mounting hardware. Made just for you in the USA, machined and assembled by Munz.
We have made some changes around here, there has been some product improvements to the 4 Bolt testers.... they now have a radiused edge and have Black anodize, and have been equipped with SEMS type Phillips head screws for faster installation. The seal has been revised to a square profile.
The 2-Bolter received the same radiused edge, and they get a go-fast Orange Anodize. The seal remains the same quad-ring.
We currently offer three different models of Testers, the Two Bolt model for the more modern intake types, the Four Bolt model for the earlier OHV big-twins, and our latest addition- the Three Bolt model designed to fit the 45 / 80 cu.in. side valve models! See the 3 Bolt page for more info!
Intake Testers that are simple and easy to use for Knuckles, Pans, Shovels, Sporties, and early Evo, that offer robust design for a lifetime of use. Each tester is not only hand-built and American made, right here in Milwaukee, but also 100% tested to ensure proper fitment and sealing.
