Product Details

Description

NGK Racking Plugs are designed for use in engines that have been tuned to achieve maximum power under specific racing conditions. The 2018+ Audi RS3/TTRS with the DAZA motor has huge power potential! Once these cars reach stage 2+ power levels, colder spark plugs are recommended.  

These spark plugs are two stages colder vs the OEM plugs. 

What does Heat Range mean?

"Generally, low power engines such as lawn mowers don’t produce a large amount of heat, hence use a low heat range (or hot) spark plug such as a 4 heat range. This means the spark plug will heat up easily and reach its optimal operating temperature. High performance engines on the other hand produce a large amount of heat, hence a high heat range (or cold) spark plug such as a 10 heat range needs to be used to resist the heat developed by the engine." - NGK

These plugs will work best on cars that are stage 2+ or higher due to the colder heat range.
