Until mid-December Bosch will throw in an interior windscreen wipe with each Super Plus wiper blade part number ordered by factors and distributors, enabling them to increase incentives to garage and retail customers.

Bosch hopes the promotion will help reduce blade replacement intervals - the average is three-and-a-half years against an industry-wide recommendation of one year - and boost annual total sales from 18.7m units for the UK parc of 27m vehicles.

“Research tells us 83 per cent of consumers don't state price as their first motivation when selecting a blade,” says product manager Paula Ferreira dos Santos. “Instead, advice from staff and trust in the brand are the two main criteria. Bosch is a well known brand and Super Plus covers 97 per cent of the market in 44 part numbers.”

Display stands, leaflets and a product catalogue are offered.
