Autolite racing spark plugs are used by many professional car drivers. They provide cut back ground electrode, anti-corrosive nickel plating and large ground electrodes for better heat transfer.
Features & Benefits:
- Yttrium-Enhanced Alloy enables up to 8% reduction in sidewire temperature for colder heat ranges designed to enable performance modifications and handle intense conditions.
- Cut back ground electrode for better ignitability of the flame kernel
- Anti-corrosive nickel plating to prevent rusting better than black oxide
This spark plug is pre-gapped, but may require minor adjustments with a Spark Plug Gap Tool / Feeler Gauge to match your engine's specifications. For proper engine performance, gaps should be within ±0.004" of OE-Recommended value. |
