so let me get this straight. your expecting to see top speed and acceleration increases from a silicone hose kit and your gonna have some one else cut them to length at cost instead of fitting them your self??
1. how would silicone hoses provide performance in these areas? Is there a hose that replaces part of the intake it self instead of attaching to it?
2. what Filter are you attaching to the end of that hose if it is supplied?
3. why dont you just cut them your self. all it takes is a cutting device such as a razor or wire cutters, with some time and patience taking little by little off at a time.
i dont understand questions like these.
if a hose doesnt replace a section of the actual intake you wont see any gains for top speed or acceleration. just reliability.
