Hey guys looking to see what options are out there for spark plugs for stage 1 APR?
Stock plugs call for replacement every 60K, and APR sells NGKs. APR would LOVE to sell you their spark plugs every 10K miles."APR recommends NGK heat range 9 (NGK-R7437-9) spark plugs gapped to 0.024" ±0.002" or 0.6mm ±0.05mm with a change interval of 10-15,000 mi or 16-24,000 km."
