1pc - NGK TR5GP - LS N/A Spark Plug

G-Power; Pre-Set Gap: 0.040"

NGK G-Power® platinum spark plugs feature a single platinum tip, 98% pure copper core and a .6 mm fine-wire center electrode for more focused sparks and better ignitability.

Features & Benefits:

• Trapezoidal ground electrode allows for higher ignitability and reduces quenching
• High-grade alumina silicate ceramic for stronger insulation to reduce dielectric punch-through (caused by spark exiting through side of ceramic)
• Trivalent plating means no anti-seize required
• Cold-rolled threads prevent cross-threading and damage to cylinder heads
• 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.
