NGK R7437-9 Racing Spark Plug - VW/Audi MQB 2.0T IS38, Hybrid, Stage 3+, 2.5T EVO With Tuning


In stock and ready to ship!


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 any VW or Audi with a Gen 3 2.0T engine with an APR stage 2 tune, IS38 turbocharger equippped vehicles with APR software, APR Stage 3 / 3+ and RS3 & TTRS 2.5T EVO vehicles with any 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 2.0T cars at stage 2, 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.
