The NGK 8374 SB05E Spark Plug Cap is essential for power sport applications where spark plugs alone may not provide sufficient noise suppression. This cap effectively reduces electromagnetic interference (EMI) and radio frequency interference (RFI), preventing issues that can cause misfires and poor engine performance. Constructed from highly durable phenolic resin and EPDM rubber, it is built to withstand extreme heat and vibration. With ceramic resistors ensuring optimum performance and reliability, this spark plug cap prevents flashover and guarantees a long service life and consistent performance.
