NGK R7437-9 Racing Spark Plug - MQB 2.0T IS38, APR Stage 3+, 2.5T EVO With APR Software
The NGK R7437-9 spark plugs operate at two heat ranges colder than stock, which results in better pre-detonation resistance and spark plug life under extreme conditions.
These plugs are recommended for VW & Audi MQB 2.0T IS38 with an APR tune,APR Stage 3 / 3+ applications where the vehicle is driven hard (e.g. heavy track use), or RS3 and TTRS 2.5T EVO vehicles with APR software.
Tech Note on APR Software equipped vehicles:
APR recommends upgrading the engine’s spark plugs to NGK R7437-9 with a .024” +/- .002” gap for IS38 turbo equipped cars at all stages, APR Stage 3 / 3+ 2.0T equipped vehicles or Audi 8V RS3 / 8S TTRS 2.5T EVO vehicles with APR software installed. If the vehicle is used for any form of racing, or extended wide-open-throttle sprints on the Autobahn, APR highly recommends upgrading the plugs for engine longevity and safety. On engines with an upgraded turbocharger, the spark plugs are required. A change interval of 10-15,000 miles or 16-24,000 km is required for engine longevity and safety.
