Please check and confirm the size before purchasing.       In account of the elasticity of the car water pipes, so recommend you choice a little bigger model than your car water pipes.       Such as if your car water pipe internal diameter is 27mm/1.06", then 28mm/1.10" internal diameter joint pipe is perfect.
Easy to install, but professional installation is highly recommended.
