Complete air cleaner system

MANN+HUMMEL supplies the air cleaner system and charge air ducts for the 2.0-litre diesel engine of the Harrier from Tata Motors

The development and series production of a complete air induction system for the premium SUV Harrier from Tata Motors enables MANN+HUMMEL to expand its activities in the Indian car market.

The expansion of activities in the Indian car segment was quite an affair for MANN+HUMMEL. Tata Motors was looking for a best-in-class solution for the air intake system in its SUV Harrier. MANN+HUMMEL was the obvious choice. This is because the Harrier is based on architecture derived from Jaguar Land Rover's D8 platform, where the filter experts had already demonstrated their expertise with the development of the air cleaner system.

International transfer of know-how

In the realization of the challenging project, the specialists from the MANN+HUMMEL Technology Center in Germany worked closely together with experts at the Indian location. They supported the experts in India with high-end solutions, especially in the use of innovative noise reduction measures. The dirty air duct is designed with a synthetic fabric which is overmolded to meet high requirements regarding noise reduction. The clean air duct includes two resonators as acoustic measures.

In the development of the air cleaner system, the development partner and series supplier was able to fully exploit its expertise in plastics. As a result, for the first time at Tata Motors plastic ducts were used for the high pressure and high temperature side of the intake system. The technology for the charge air duct completely produced in plastic on the cold side of the charge air system represents the European state of the art.


The SUV benefits from the light and compact air cleaner system. The consistent implementation of a module strategy and international transfer of expertise enables MANN+HUMMEL to support an economic local supply to Tata Motors in its domestic market.
