NGK High Performance Iridium Spark Plugs for MINI

These high performance NGK spark plugs are a single iridium cold heat range spark plug. These plugs are an ideal upgrade for tuned MINI Cooper S and JCW’s because these plugs are a colder heat range at 8, plus they are iridium instead of platinum, and they have a small 0.6mm gap which helps the stock coils when running heavy boost.

We recommend running these plugs with the Manic Motorsport ECU tunes.
