Senior Aftermarket’s emissions led products have found themselves in many new industries than just passenger car where we started in the 1990’s and we are now established in almost all industries where exhaust systems rely on after-treatment.

This diversity has ensured that we have gained vast knowledge of the operating conditions our products experience in each of these industries and thus our components have been developed to survive no matter where they are installed.

The tightening emissions legislation and its effect on the automotive and peripheral markets will only assist the spread of our products further.
