Description
The NGK BPR5EIX-11 iridium spark plug delivers superior ignition reliability and extended service life by leveraging a precision-engineered center electrode that’s 25% smaller than platinum alternatives. This reduced electrode diameter lowers voltage demand on your ignition system, reducing wear and improving cold-start performance across a wider range of operating conditions. If you’re running a high-performance engine or simply want to maximize the time between plug changes, iridium construction is the proven standard in motorsports and street applications alike.
