Supertech intake valves are made exclusively from an enhanced versions of EV8 (21-4N) steel. This is the highest grade of steel available and provides the strength to withstand just about any application.

Valves play a critical role in any performance-orientated engine.

The power an engine produces is limited to airflow. As the smallest chokepoint in your cylinder head, performance valves are engineered to increase airflow by limiting turbulence created by valve stem obstruction and careful detailing of the valve head and valve angles.

This product has many different sizes making it easy to fit clips in other parts of the car.
I was working on my grandson Honda. It was missing the plastic clips to hold the fender liners in place. This worked great and helped hold the fender in place. I used the puller tool many times on other plastic parts on the car.

Fit as described
Used to install an inner fender liner. Seem a little more fragile than OEM, but suitable for the intended use and much less expensive.
