1971 Volkswagen Fastback Spark Plug

Part Number: 17339-03399103

Notes: Nickel -- Gap 0.028 in

Features:

• Heavy-duty yttrium enhanced nickel-copper center electrode ensures superior reliability and durability for up to 50% longer performance life vs. standard copper plugs
• Copper core provides broader heat range to resist pre-ignition and fouling
• Nickel-plated rolled threads provide superior resistance to corrosion and do not require anti-seize - saving time
• Angled, ribbed insulator design prevents misfire due to flash-over
• Metal glass fused resistor maximizes interference suppression
• Bosch Super Plus, with a heavy-duty yttrium-enhanced copper core center electrode, is the longest lasting copper core spark plug on the market.
