* The Heavy Throttle kit consists of the following parts:

1) One 3/4" U hose.
2) One 5/8" L hose.
3) One 3/4" S hose.
6) One 3/4" to 5/8" reducer.
7) 6 hose clamps.

1/2/6 are used for the upper heater hose. 3 is for the lower. The upper hoses need to be trimmed to fit, and fit with no problems once you mount them.

The lower hose #3 is the one that is the problem. This is Gates part number 19606. The specs for this part is below for your reference.

As you can see below, this part is 3/4" throughout. The JDM SR nipple is 3/4", but since the USDM heater core is 5/8", this will not work. I installed this part and the hose was leaking at the heater core because it was 1/8" too large.

What I had to do was to make a custom hose, using a 3/4" to 5/8" reducer. The lower hose that was supplied with the kit was useless.

$35 + shipping is a good price if you don't want to piece together your own kit, but since the lower hose was useless to me, it wasn't worth it to me. You can get the U, the L, and the reducer for probably $15-20. Add a few more bucks for clamps and you're good to go.

I'm not knocking Heavy Throttle at all. I'm just commenting on their products from what I saw. They should really redo the lower hose for the kit.
