Excellent for forced induction motors
Best clamp for supercharged motors. Much better bolts and welds

Saved me $$$
Bought these when I started my trucking company and threw them in the truck. While going up a hill on I-20 west of Atlanta my truck lost power and I barely made up the hill. I popped the hood and saw the turbo hose has popped off and the clamp was gone. 5 minutes later I threw it on and was back on the road. That was 2 years ago, and it is still going strong.

Great purchase, fit exactly as advertised
Exactly what I needed. I was worried about what my measurements were, and how the chart was read, but I pulled the trigger on the exact size I needed, based on what the I.D. of the clamp is, and hit a home run! These clamps are much better quality than your general 'eBay intercooler kit' t-bolt clamps. If I have any more needs in the future for t-bolt clamps, I'm absolutely buying from both this seller, and company. I am happy that they use nyloc nuts, instead of using double-nuts. They have held up to several thousand miles, and haven't slackened-up even a fraction. I am running 19psi, and they have done nothing but performa! The value for money paid on these is excellent, you won't be disappointed in these at all!

Works, but don't use impact
Used 3/8 Ryobi impact and broke the bolt. Should probably work fine, but can't take the clamp load.

works as it should
works does as it should. use on more places than Fuel injection hose. Clamps nicely for other hoses. Doesn't deform the hoses, but allow leaks. Just don't over tighten. The larger surface area is great.

Wouldn’t tighten up to 1 1/2” as advertised.

Sizes are larger than advertised
Not a advertised. These clamps at their tightest are not 4.5 inch but rather 4.625 and this fit to loose. Wasn't able to use them in the end. Waste of money
