All EBC brake pads that are used for highway use on cars, trucks and SUV's are tested to ECE R90 brake safety regulations and are considered a legal equivalent to any OEM or Original brake pads. The R90 rigorous testing procedures guarantee not only brake pad quality and performance on a model by model basis but also oversee conformity of production at EBC. This means EBC parts are as good as, or in most cases better than original or OEM parts.

Speaking of oxygen sensors......An oxygen sensor or sometimes called a lambda sensor or o2 sensor, is an electronic device that looks similar to a spark plug that measures the proportion of oxygen and fuel in your vehicles exhaust system. oxygen sensors should be replaced at regular intervals, on most cars that's about every 50,000 to 60,000 miles. If you have to replace your catalytic converter you should ALWAYS replace the oxygen sensor as well.
