The new Bosch Super-4 outperforms conventional spark plugs in every situation. It uses state-of-the-art 'surface-air-gap' technology, and features four thin ground electrodes with one pointed, silver-plated centre electrode. This enables the ignition spark to choose the best path for reliable ignition, and according to the load placed on the engine.
·Increased Acceleration:Air-fuel mixture deposits occur in driving primarily during heavy acceleration. The Super-4 spark plug from Bosch with increased ignition reliability prevents misfiring and therefore guarantees improved acceleration. In a trial, acceleration from 19 to 75 mph in third or fourth gear resulted in 0.4 s gain in each case. The acceleration distance decreased by five meters, providing driver and passengers with improved safety during overtaking.
·Less chance of misfiring:Bosch 'surface-air gap' technology ensures a more even wear of the electrodes. This, in turn, leads to a more reliable spark. Since the probability of a spark choosing one of the eight possible paths is equal, wear on the ground electrodes is distributed evenly over all four electrodes.
·Better cold starting performance:Thanks to the improved low-temperature behaviour and self-cleaning feature, up to three times as many cold starts are possible than with conventional spark plugs. Environmental protection and protection for the catalytic converter The improved cold start behaviour and increased ignition reliability even in the warm-up phase increases fuel combustion and thus reduces HC-emissions. This also has the effect of extending the service life of the catalytic converter.
·Greater Spark Power:The spark in the Super 4 loses less power than the spark in a conventional spark plug due to the four thin ground electrodes (less resistance). Spark plug efficiency therefore increases because the air/fuel mixture has up to 40% more power available for every ignition.
