Long base candle MALOSSI MHR by DENSO IW34 iridium competition (very cold index)

Here is the MALOSSI MHR by DENSO IW34 iridium competition long base spark plug (very cold index).

The spark plug par excellence for over- equipped engines , it is the spark plug that is used for the MHR team 80 cup , really nothing to do with any other spark plugs, solidity, self-cleaning, spark...

This is the result of many studies. The most top of the range that we can have especially for this model which is the IW 34 reviewed and corrected from the olive to the electrode! The very high price is explained by the components and the study, it is worth it for really advanced engines because the gains in performance and longevity are really present. Only use this type of spark plug once the carburetion has been adjusted, when adjusting, use the original type spark plug with a warmer index. There is no equivalent for this candle which is really solid and ultra efficient.

Features :

-Thread type: long base

-Central electrode: iridium, laser manufacturing , Ø0.40mm

- Response electrode: cut system

-Intended for engine types: very powerful and equipped

- Index: very cold (34) (= B11 on NGK )

Please note, this spark plug has a 5kΩ resistor, so install it with a competition 5kΩ resistive suppressor.

An important factor in the choice of candles is the heat index which defines the amount of heat that the candle can exclude from the combustion chamber. Spark plugs that operate at too high or too low a temperature create problems: the former do not cool sufficiently and cause pre-combustion, the latter generate a carbon deposit on the electrodes.
Denso operates between 400 and 900 degrees, an ideal range to allow self-cleaning of the spark plug between one combustion and another.

This one therefore offers :

1. more powerful spark with lower voltage
2. Better ignition and quicker acceleration.
