P-Tronic regularly uses demonstration additional box units during fairs, car shows or when presenting new products to the press. These power kits (different from diesel or engine chiptuning) are then brought back to as new condition by our technical service, before being sold by ourselves.
Coming with a total 3 year guarantee, these box units, available in limited quantities, can be bought by simply sending a request by e-mail, by filling out our on-line form or by telephone. Contact us, tell us the brand and model of car, the year, the type of engine and its power, and we will tell you if we have a suitable used box unit available.
