Mopar Performance 68303917AA Double Platinum Spark Plug RE14PLP5

The Mopar 68303917AA is a genuine OEM double platinum spark plug (plug code: RE14PLP5) engineered to factory specifications for Chrysler, Dodge, and Jeep V6 engines. As a critical component in the ignition system, this spark plug delivers a precise electrical spark to ignite the air-fuel mixture in the combustion chamber, producing reliable power and efficient engine operation.

This plug features a double platinum design — a platinum-tipped fine-wire center electrode paired with a platinum pad on the copper-core ground electrode — providing exceptional wear resistance and a longer service life compared to standard copper plugs. The V-trimmed ground electrode and tapered electrode design sharpen spark focus and reduce quenching for consistent ignition.

Key Features:

• Double platinum electrodes — platinum center and platinum pad ground electrode for minimized spark gap growth and long service life up to 100,000 miles
• Fine-wire center electrode for greater ignitability and more efficient combustion
• V-trimmed ground electrode promotes a sharper spark focus and reduces misfires
• Heat-Active alloy construction reaches optimal operating temperature quickly and maintains stable temperatures under varying engine loads
• Triple-sealed interior with copper core reduces failure due to heat and mechanical stress
• Tapered seat design with resistor type for broad compatibility
• Torque spec: 7–15 lb-ft (cast iron or aluminum heads)
• Genuine OEM Mopar part — built to factory specifications
