When you need to replace the spark plugs in your 1972-1991 Base/ZR1 Corvette, consider these 4 count Denso #4509 Platinum TT Spark Plugs. This twin-tip (TT) spark plug is meant to be one-step beyond traditional platinum plugs. The 1.1mm platinum center electrode is augmented by a titanium-enhanced ground electrode, which delivers maximum ignition energy under the fiercest of conditions that the combustion chamber of your engine can dish out.

  • The ground electrode's design is a free-standing firing pad that reduces quenching to generate a more power spark. You'll get faster starts and improved fuel economy.
  • Note: P65 warning for California residents.
  • Features:
  • Platinum/titanium design.
  • Twin tips.
  • 1.1mm platinum center electrode.
  • Minimum-quench electrode design.
  • Improved fuel economy.
  • Faster starts.
  • Increased engine efficiency.
  • 4 count.
  • Fits:
  • C3 1972-1982 Base / ZR1 Corvettes.
  • C4 1984-1991 Base / ZR1 Corvettes.
  • Corvette Is A Registered Trademark Of The General Motors Corporation.
