Super Racing RR15YPP-1 Spark Plug
The platinum on the center electrode ensures stability of electrode distance over a very long time. The small diameter of electrode tip does not prevent propagation of the flame front in the combustion chamber and contributes to increase in engine power. This also suppresses the quenching effect during cold starts.
- Platinum contacts on center electrode only
- Perfect ignition of air/fuel mixture
- Platinum on the center electrode ensures stability of electrode
