In order to reduce particulate matter emitting from on or off-road vehicles the EPA (BS norms as applicable on domestic vehicles) has mandated the use of filters, the most common of which is the DPF.

The usage of Q-Shield™ technology results in cooler and denser air due to the reduction of heat levels in the engine compartment. This results in a more efficient burning of fuel leading to reduced amounts of gases from the exhaust system. The exhaust system is also shielded so that maximum heat is retained to reduce the amount of regenerations.
