When you need to replace the spark plugs in your 1986-1992 Base/ZR1 Corvette, consider these 4 count Denso #4503 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.
