Cone X Plugs 2-in-1

Good product

Worked just as it was supposed to. It worked just fine checking for engine and exhaust leaks. Sadly, no leaks this time, so the search for the mystery problem continues.

Well made. A real asset in Diag toolbox. Good price to quality point. Would buy again!

Great great adapter for their smoke machine, no defects and no problems holding its seal. So much so that it popped off my intake from pressure before anything else! my only complaint (which is barely one) is that I had to really tighten down my intake pipe around it on a 2015 F150 2.7l ecoboost. Great pricing, and gets the job done no problem!

high quality, very effective

you need this. Makes things, testing very fast and quick.Don't have to screw around blocking off stuff with plastic, gloves, etc.

thick plugs lots of sizes

Genuinely surprised how well it works. I’m a diag tech at my shop and each plug seals almost perfectly. Makes looking for an intake/vacuum leak very easy when using a smoke tester.
