Installation from new vehicles is recommended.
I use it on my ZX6R EF model.
It is very easy to install, just attach it via the claws and bolt on top of the Radiator.
The fins of the Radiator are often damaged by flying rocks that cannot be suppressed by the Front Fender alone, or by flying rocks from the car in front. Even if the fins are crushed, it will not affect driving, but it will definitely reduce the cooling performance of the coolant, so it is better to install the Radiator core guard from new.
In addition, in rare cases, the Radiator is damaged by stepping stones and leaks coolant. The Radiator core guard is a must, especially when you are out on a tour, because it takes a lot of time and money to move the wrecker, and it can ruin your happy memories.
There is also a merit that if the Radiator core guard is installed, the fins are less likely to be crushed and the resale value will be better.
As a result, we have not been able to confirm any degradation in cooling performance (less airflow) due to the installation of the Radiator core guard.
The Manufacturer also uses a finer mesh for the center section, which is subject to a lot of stepping stones, and a coarser mesh for the others, so I think there is little difference.
