Ok I'm trying to get these clamps for my IC couplers and intakes because the one that i got in the local hardware store are kind of cuting them because of those cuts in them or whatever.

Now someone please tell me the sizes, cause i don't understand this fraction things.



I need them for the stock IC Piping, basically for stock Y-pipe, Ic to y-pipe, Ic to pipe that goes to UIM and Apexi intake.



the sizes on these clamps are in millimeters

59-82 mm

29-76 mm

65-89 mm



I know i need 10 of them all together.



thanks

 

When I go to the page you linked it shows the diameter range in inches in the description line.



I have some very similar or the same t-bolt clamps on my car. I believe the size encompassing 3" diameter is the one you want (but I'm not at home to check). Just tighten the clamp on the hose to where you can still slide it off, then measure the i.d. If you're using stock turbo, crossover pipe, IC and hoses, the size is the same for all.

 

The T-bolt clamps only have a total range of 5/16" and can't match the metric ranges you listed above. That's why you have to measure the outside of the hose you're clamping and then choose a clamp from the list that's a tad bigger at it's widest; for e.g. to clamp a 3" diameter hose, part # TB288 would be a good bet.



Have fun,

 

Yeah the best thing would be to measure, i'm just too lazy to take all that stuff off again and then put it on, and then again take it off to install these new clamps.

 

It is worth it to use these clamps at least on the coupler from the turbo outlet to crossover pipe. The rest of the connections aren't as important, IMHO.



The clamps I'm using are a different brand with a 3" - 3 1/4" range. They work fine on the stock hoses and rubber couplers. If I was using thinner silicon IC hoses I'd go a tad under 3" for the minimum size.

 

I beleive it's 2 & 3/4" ID you can buy them from www.turbohoses.com or if you know the part number it's cheaper from McMasterCar.
