How to choose the best spark plugs from the variety of brands on the market? A question that worries almost every motorist. Today, in addition to famous brands such as BRISK, Bosch, NGK, Beru, Denso, there are many little-known manufacturers with products of dubious quality.

 In order not to get lost in this abundance and make the right choice, we carried out a number of comparative test measurements on the Dynostend. Measurements that will really show the effect of spark plugs on the power parameters of a car engine.

 We chose three non-standard vehicles to participate in the experiment:

Audi A4 2.0 TFSi 270 HP

BMW 325 6-cyl. 200 h.p.

BMW X5 4.8 360 HP

 The first test was carried out on an Audi A4 2.0 TFSi with 270 hp. and for this we took two types of spark plugs from the Czech BRISK plant: iridium BRISK Iridium, revolutionary BRISK EVO and compared them with the original Audi / VW Iridium spark plugs. What came of this and on which spark plugs the car showed the best power values, see our video:

Below is a table with the measurement results:

All test measurements were carried out with the technical support of Dieselok.md specialists (professional car chip tuning).
