JL52-15241651: 152.4~165.1mm / 19.0mm / 1 piece

Definitely recommended for models with a supercharger.
Traditional hose clamps will collapse if you tighten them too much, and fall out if you don't tighten them too much...
There was such a problem, but the tightening torque can now be managed.

With heavy duty high torque clamp,
Boasts torque performance more than three times that of normal worm gear clamps.
It is mainly used in exhaust and intake areas where vibration is likely to occur.
Tighten the T-bolt with a lock nut, so you don't have to worry about it coming loose.
It also has a structure that tightens the hose evenly, so you can grip the hose firmly.

The bolts and nuts are also made of rust-resistant SUS.
The nut uses a stainless steel nylon nut that is hard to loosen.
Adopts a ROLLED-EDGE design (R processing on both ends of the band makes it difficult for the hose to get wedged).
