Adjust the slider to match your daily driving habits. City driving involves stop-and-go traffic under 45mph, while highway driving represents sustained speeds over 55mph.
Aerodynamic Speed Penalty
EPA highway tests average roughly 48 mph. Driving at 75 mph increases aerodynamic drag exponentially. Expect your real-world highway fuel economy to drop by roughly 15-20% at interstate speeds.

VACUUM HARNESS ASSEMBLY HOSES BECOME LOOSE AND CAN CONTACT ENGINE EXHAUST PORTS. CONTACT WITH EXHAUST EXPOSES HOSES TO HIGH TEMPERATURE WHICH CAUSES CARBONIZATION OF THE HOSES MATERIAL.
Consequence & Remedy
Consequence: AS A RESULT, COMBUSTION OR AUTO IGNITION CAN TAKE PLACEAND THE HOSE IGNITES WHICH CAN CAUSE SEVERE ENGINE COMPARTMENT DAMAGE ANDPOSSIBLE LOSS OF VEHICLE DUE TO FIRE.
Remedy: REROUTE VACUUM HOSES TO PRECLUDE CONTACT WITH EXHAUST SYSTEM.
